Objectives: Eating while distracted has been associated with a higher body mass index (BMI), whereas mindful eating and episodic memory for recent eating have shown the opposite pattern. This pre‐registered, global study (https://osf.io/rdjzk) compared the relative association between these variables (and four "positive controls": restraint, disinhibition, emotional eating, plate clearing) and self‐reported BMI. The timing of data collection (April–May 2020) during the SARS‐CoV‐2 pandemic enabled an investigation of the impact of stay‐at‐home restrictions imposed on the UK population on the measures of eating behavior. Methods: An online survey was completed, including: (i) demographic data (e.g., self‐reported BMI), (ii) Likert ratings assessing episodic memory for recent eating, mindful eating, cognitive distraction, restrained eating, emotional eating, disinhibition and plate clearing over the last 12 months and the last 7 days (during the first UK COVID‐19 lockdown), and (iii) the Mindful Eating Questionnaire (MEQ). Results: A large adult sample participated (N = 846; mean (SD) age = 33.0 (14.3) years; mean (SD) BMI = 24.6 (5.6) kg/m2). Mindful eating (MEQ‐total score) was associated with a lower self‐reported BMI (β = −0.12; 95% CI = −0.20, −0.04; p = 0.004), whereas disinhibited eating was associated with a higher self‐reported BMI (β = 0.30; 95% CI = 0.21, 0.38; p < 0.001). In UK participants (n = 520), consistent changes in eating behavior during lockdown were not found. For those that did experience change, decreases were reported in; emotional eating, disinhibited eating, focusing on taste during a meal (a measure of mindful eating), and using a smart phone while eating. Conclusions: These findings provide evidence in a large global sample for associations between BMI and (i) mindful eating, and (ii) disinhibited eating. Future research should evaluate whether mindful eating demonstrates a prospective association with body weight and should consider mechanisms of action. [ABSTRACT FROM AUTHOR]

However, long-term avoidance of animal foods can lead to inadequate intake of essential nutrients like iron and vitamin B-12, critical for maintaining blood health. Iron deficiency is a widespread nutritional problem, especially in vegetarian diets, due to the reduced bioavailability of non-heme iron in plant foods. This study aimed to provide a detailed comparison of anemia frequency and other hematological parameters between vegetarian and omnivorous diets, thereby offering insights into the nutritional adequacy and health outcomes of these dietary habits. Methods: The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilizing a prospective cohort from the UK Biobank. Participants aged 40-69 years were investigated for anemia prevalence in vegetarian and omnivorous diets. Data collection included informed consent procedures, a touchscreen questionnaire addressing sociodemographic and lifestyle factors, and a computer-assisted personal interview. Blood samples were collected for complete blood cell counts and hematological assays. Statistical analysis involved linear regression models, adjusted for age, sex, menopausal status, and smoking status. Results: The study found that vegetarians and other low or non-meat eaters had slightly lower age-adjusted hemoglobin concentrations and were more likely to be anemic compared to regular meat eaters. However, a well-balanced vegetarian diet did not significantly differ in iron-deficiency anemia incidence compared to omnivores. The study also noted differences in white blood cell parameters and platelet characteristics between diet groups, suggesting potential differences in immune function. Conclusion: The research concluded that a well-planned vegetarian diet does not increase the risk of iron-deficiency anemia compared to omnivorous diets. The key is dietary quality and appropriate planning, ensuring sufficient iron intake to prevent deficiency and support overall health. The findings contribute to the discussion about the adequacy of vegetarian diets and their role in preventing chronic conditions. [ABSTRACT FROM AUTHOR]

Background: Gastric ultrasound is an effective, non‑invasive method to assess the nature and volume of gastric content in the pediatric population. Recently, the UK, European, and French Pediatric Anesthesia Societies recommend fast for clear fluids in children for 1 h. However, studies showing that 1 h of fasting is safe in the pediatric population are still scarce. This study aims to verify by ultrasound evaluation if 1 h of fasting for clear liquids is sufficient to have an empty stomach before anesthetic induction. Methodology: Patients between 11 months and 16 years of age scheduled for elective outpatient surgery were included. A qualitative and quantitative ultrasound evaluation was performed by calculating the cross‑sectional area (CSA) of the gastric antrum, 1 h after ingesting a volume of 3 mL/kg of a non‑carbonated sports drink, before anesthetic induction. Results: Fifty patients were included. The average CSA measured by ultrasound was 2.85 ± 1.64 cm2 with an average calculated total volume of 12.9 ± 11.06 mL. All patients had an empty stomach criterion (calculated volume ≤1.5 mL/kg) during the ultrasound evaluation, with an average of 0.40 ± 0.23 mL/kg. With the qualitative assessment of gastric volume, 19 patients (38%) were classified as grade 0, 31 patients (62%) as grade 1, and none as grade 2. Conclusion: One hour of fasting after ingestion of 3 mL/kg of a non‑carbonated sports drink is sufficient to meet ultrasound criteria for an empty stomach in a pediatric population undergoing elective outpatient surgery.

Aims: This paper examines the co-occurrence of drinking alcohol and eating in Great Britain. Applying a practice-theoretical framework, it attends primarily to the nature and characteristics of events – to social situations. It asks whether drinking events involving food are significantly different from those without, whether differences are the same at home as on commercial public premises, and whether differences are the same for men and women. The focus is especially on episodes of drinking with meals at home, an infrequently explored context for a substantial proportion of contemporary alcohol consumption. Data: Employing a secondary analysis of commercial data about the British population in 2016, we examine reports of 47,645 drinking events, on commercial premises and at other locations, to explore how eating food and consumption of alcoholic beverages affect one another. Three types of event are compared – drinking with meals, with snacks, and without any food. Variables describing situations include group size and composition, temporal and spatial parameters, beverages, purposes, and simultaneous activities. Basic sociodemographic characteristics of respondents are also examined, with a special focus on the effects of gender. Results: Behaviours differ between settings. The presence of food at a drinking episode is associated with different patterns of participation, orientations, and quantities and types of beverage consumed. Gender, age, and class differences are apparent. Conclusions: Patterns of alcohol consumption are significantly affected by the accompaniment of food. This is a much-neglected topic that would benefit from further comparative and time series studies to determine the consequences for behaviour and intervention. [ABSTRACT FROM AUTHOR]

Considerable uncertainty remains regarding associations of multiple risk factors with Alzheimer's disease (AD). We aimed to systematically screen and validate a wide range of potential risk factors for AD. Among 502,493 participants from the UK Biobank, baseline data were extracted for 4171 factors spanning 10 different categories. Phenome-wide association analyses and time-to-event analyses were conducted to identify factors associated with both polygenic risk scores for AD and AD diagnosis at follow-up. We performed two-sample Mendelian randomization analysis to further assess their potential causal relationships with AD and imaging association analysis to discover underlying mechanisms. We identified 39 factors significantly associated with both AD polygenic risk scores and risk of incident AD, where higher levels of education, body size, basal metabolic rate, fat-free mass, computer use, and cognitive functions were associated with a decreased risk of developing AD, and selective food intake and more outdoor exposures were associated with an increased risk of developing AD. The identified factors were also associated with AD-related brain structures, including the hippocampus, entorhinal cortex, and inferior/middle temporal cortex, and 21 of these factors were further supported by Mendelian randomization evidence. To our knowledge, this is the first study to comprehensively and rigorously assess the effects of wide-ranging risk factors on AD. Strong evidence was found for fat-free body mass, basal metabolic rate, computer use, selective food intake, and outdoor exposures as new risk factors for AD. Integration of genetic, clinical, and neuroimaging information may help prioritize risk factors and prevention targets for AD. [ABSTRACT FROM AUTHOR]

Simple Summary: Intensive farm conditions have an impact on welfare and can reduce the locomotor behavior of calves. The Actiwatch-Mini® (Cambridge Neurotechnology Ltd., Cambridg, UK), an actigraphy-based data logger was used to record the total locomotor behavior of 30-day-old calves, which showed diurnal daily rhythmicity. An individual daily rhythm of total locomotor behavior has also been found and varied in the same subject from day to day, and from subject to subject, and these variabilities need to be taken into account during the farm monitoring. Housing confinement, adaptation to different light/dark conditions, and social deprivation could modify the amount of total locomotor behavior of calves recommended for their psychophysical health. Total locomotor behavior was recorded by means of an activity data logger every 5 min for 6 consecutive days. To do that eight clinically healthy 30-day-old Holstein calves living in calf boxes under natural photoperiod and environmental conditions were enrolled. ANOVA (analysis of variance) showed a statistical effect of the day of monitoring and animal. In the temporal distribution of the resting–activity frequency, it was observed that the calves presented periods of total locomotor behavior with the existence of two peaks, one between 06:00–07:00 and another between 17:00–18:00, which corresponds to time of food intake. In all animals, a diurnal daily rhythm of total locomotor behavior was observed during time of monitoring. Intrasubject and intersubject variabilities were statistically different in mesor, amplitude, and robustness of rhythm. In conclusion, the total locomotor behavior showed a diurnal daily rhythmicity in 30-day-old calves. The characteristics of rhythm were different from individual to individual and from day to day. The recorded intersubject variability must be taken in consideration during the monitoring of farm animals and justifies the application of the device to each animal, as precision livestock farming suggests.

Objective: To identify eating occasion-level and individual-level factors associated with the consumption of larger portions in young children and estimate their relative importance. Design: Cross-sectional. Setting: Data from parent-reported 4-d food diaries in the UK National Diet and Nutrition Survey (2008–2017) were analysed. Multilevel models explored variation in eating occasion size (kJ) within (n 48 419 occasions) and between children (n 1962) for all eating occasions. Eating contexts: location, eating companion, watching TV, and sitting at a table and individual characteristics: age, gender, ethnicity and parental socio-economic status were explored as potential correlates of eating occasion size. Participants: Children aged 1·5–5 years. Results: Median eating occasion size was 657 kJ (IQR 356, 1117). Eating occasion size variation was primarily attributed (90 %) to differences between eating occasions. Most (73 %) eating occasions were consumed at home. In adjusted models, eating occasions in eateries were 377 kJ larger than at home. Eating occasions sitting at a table, v. not, were 197 kJ larger. Eating in childcare, with additional family members and friends, and whilst watching TV were other eating contexts associated with slightly larger eating occasion sizes. Conclusions: Eating contexts that vary from one eating occasion to another are more important than demographic characteristics that vary between children in explaining variation in consumed portion sizes in young children. Strategies to promote consumption of age-appropriate portion sizes in young children should be developed, especially in the home environment, in eating contexts such as sitting at the table, eating with others and watching TV.

Cyanide is a prevalent, lethal chemical. Possible sources of exposure include products of combustion, plant material, industry, chemical warfare and terrorism. Retrospective review of UK Poisons Information Database of telephone enquiries to the National Poisons Information Service between 1st January 2008 and 31st December 2019 where cyanide poisoning was considered a possibility. Data extracted included demographics, exposure source, clinical features, Poisoning Severity Score, lactate concentration and antidotes given. A total of 1,252 cases of suspected cyanide poisoning were identified, 239 (19%) involved children under 10 years. The commonest sources of exposure were ingestion of plant material (437 cases; 35%) and smoke inhalation (399; 32%). Smoke inhalation caused the majority of severe and fatal cases (139; 71%). Clinical features associated with fatal outcomes were cardiac arrest (OR 36.4; 95% CI 14.4–92.2), hypotension (15.8; 7.0–35.9), coma (10.8; 5.6–21.0) and lactic acidosis (7.8; 4.1–14.8). 110 patients (9%) were given an antidote and 40 patients (3%) died. Lactate concentrations correlate with Poisoning Severity Score category (r = 0.6, p < 0.0001). Serum lactate <2.0 mmol/L was associated with Poisoning Severity Score None or Minor (sensitivity 76%; specificity 86%) and >11.0 mmol/L was associated with fatal outcome (sensitivity 74%; specificity 80%). 61 cases (5%) had severe carboxyhaemoglobin toxicity (COHb >30%). This was associated with a fatal outcome (OR 7.0; 95% CI 1.5-33.7) and there was positive correlation between carboxyhaemoglobin and Poisoning Severity Score, r = 0.57, p < 0.0001. Most cases of ingestion of plant material involved children under five years and resulted in no or mild symptoms. In adults smoke inhalation was associated with the most severe poisoning. The lactate cut-off values associated with each severity score calculated in this study are lower than the values used by NPIS on TOXBASE. Analytical conformation of cyanide exposure was unavailable in the majority of case, limiting the strength of these conclusions. [ABSTRACT FROM AUTHOR]

Recent years have seen an increase in actions to address a key feature of food in the Anthropocene: the over‐production and consumption of animal‐based foods or "animalisation" of diets. However, it is unclear whether such efforts can be understood as a coherent institutional level response that will challenge hegemonic dietary biopower, a regime of governance that normalises and reproduces animal‐based food consumption. Building on scholarship that explores food governance initiatives in urban contexts and dietary biopower across a range of empirical cases, this paper explores whether, how, and with what consequences governance actors within urban food partnerships (UFPs) of the UK Sustainable Food Cities (SFC) network are working to reframe dietary biopower so that humans are disciplined to eat less animal‐based food and instead to adopt a more plant‐centred diet. Document analysis and semi‐structured interviews with SFC representatives suggest the breadth and depth of current UFP actions do not add up to a sustained challenge to hegemonic, animal‐based dietary biopower. Rather, they reveal a plant‐centred dietary biopolitical project in the making, while specific cases suggest that this project is more accurately conceptualised as arrested due to the pursuit of food system actions that are counter to and in tension with the promotion of plant‐centred eating. We suggest that a more coherent reframing of dietary biopower would entail urban food governance actors engaging consistently and robustly with the debates surrounding animal‐based foods, as well as identifying and enacting synergies between plant‐centred eating, food poverty, and local economic development agendas. The paper explores whether, how and with what consequences governance actors within the urban food partnerships of the UK Sustainable Food Cities network are working to reframe dietary biopower so that humans are disciplined to eat less animal‐based food and instead to adopt a more plant‐centred diet.

There is a lack of research documenting the weight-making practices of mixed-martial-arts (MMA) competitors. The purpose of the investigation was to quantify the magnitude and identify the methods of rapid weight loss (RWL) and rapid weight gain (RWG) in MMA athletes preparing for competition. Seven athletes (mean ± SD, age 24.6 ± 3.5 yrs, body mass 69.9 ± 5.7 kg, competitive experience 3.1 ± 2.2 yrs) participated in a repeated-measures design. Measures of dietary intake, urinary hydration status, and body mass were recorded in the week preceding competition. Body mass decreased significantly (p < .0005) from baseline by 5.6 ± 1.4 kg (8 ± 1.8%). During the RWG period (32 ± 1 hr) body mass increased significantly (p < .001) by 7.4 ± 2.8 kg (11.7 ± 4.7%), exceeding RWL. Mean energy and carbohydrate intake were 3176 ± 482 kcal⋅day-1 and 471 ± 124 g⋅day-1, respectively. At the official weigh-in 57% of athletes were dehydrated (1033 ± 19 mOsmol⋅kg-1) and the remaining 43% were severely dehydrated (1267 ± 47 mOsmol⋅kg-1). Athletes reported using harmful dehydration-based RWL strategies, including sauna (43%) and training in plastic suits (43%). Results demonstrated RWG greater than RWL, this is a novel finding and may be attributable to the 32 hr duration from weigh-in till competition. The observed magnitude of RWL and strategies used are comparable to those which have previously resulted in fatalities. Rule changes which make RWL impractical should be implemented with immediate effect to ensure the health, safety and wellbeing of competitors. [ABSTRACT FROM AUTHOR]

Background Magnets and button batteries (BBs) are dangerous ingested foreign bodies in children. The scale and consequences of this public health issue in the UK are unknown. This study aims to report the current management strategies and outcomes associated with paediatric magnet and BB ingestion in the UK. Methods This multicentre, retrospective observational study involved 13 UK tertiary paediatric surgery centres. Children aged under 17 years, admitted between 1 October 2019 and 30 September 2020, following magnet, or BB ingestion were included. Demographics, investigations, management, and complications were recorded. Results In total, 263 patients were identified, comprising 146 (55.5 per cent) magnet, 112 (42.6 per cent) BB, and 5 (1.9 per cent) mixed magnet BB ingestions. Median (interquartile range) age was 4.8 (2.0–9.1) years and 47.5 per cent were female. In the magnet group, 38 (26.0 per cent) children swallowed single magnets, 3 of whom underwent endoscopic retrieval for oesophageal or gastric impaction. Of the 108 (74.0 per cent) children who swallowed multiple magnets, 51 (47.2 per cent) required endoscopic or surgical intervention, predominantly for failure of magnets to progress on serial imaging. Bowel perforations occurred in 10 children (9.3 per cent). Younger age and ingestion of greater numbers of multiple magnets were independently associated with surgery. BB ingestion caused morbidity in 14 children (12.5 per cent) and life-threatening injuries in two (1.8 per cent); the majority were caused by oesophageal BBs (64.3 per cent). Conclusion Multiple magnet and BB ingestions are associated with significant morbidity. Action must be taken at an international level to regulate the sale of magnets and BBs, and to raise awareness of the risks that these objects pose to children. [ABSTRACT FROM AUTHOR]

Aim: To examine the cross‐sectional associations between single nutrient intakes and posteriori nutrient‐based dietary patterns and periodontal disease risk in a subset of the UK Biobank cohort. Materials and Methods: Dietary data were collected by 24‐h dietary recall on up to five separate occasions over 16 months. A touchscreen questionnaire was used to collect oral health information. Participants were considered at high risk of periodontal disease if they reported having painful gums and/or bleeding gums and/or loose teeth. Principal component analysis identified four nutrient‐based dietary patterns from 20 nutrients. Logistic regression was used to estimate the odds ratio of periodontal disease risk for single nutrients and nutrient‐based dietary patterns. Results: A total of 9476 participants (mean age 56.2 years [SD 8.0]) were included in the analysis. Higher intakes of vitamin B6, B12, C, and E, folate, iron, potassium, magnesium, polyunsaturated fatty acids, and total sugar were associated with a lower risk of periodontal disease. Higher intake of saturated fat was associated with an increased risk. A dietary pattern characterized by high micronutrients and fibre intake was associated with low risk of periodontal disease. Conclusion: Within this sample of middle‐aged and older adults, a "high micronutrient and fibre" dietary pattern was associated with reduced risk of periodontal disease. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study is to describe ultra-processed food and drinks (UPFDs) consumption, and associations with intake of total sugar and dietary fibre, and high BMI in adults across Europe. Methods: Using food consumption data collected by food records or 24-h dietary recalls available from the European Food Safety Authority (EFSA) Comprehensive European Food Consumption Database, the foods consumed were classified by the level of processing using the NOVA classification. Diet quality was assessed by data linkage to the Dutch food composition tables (NEVO) and years lived with disability for high BMI from the Global Burden of Disease Study 2019. Bivariate groupings were carried out to explore associations of UPFDs consumption with population intake of sugar and dietary fibre, and BMI burden, visualised by scatterplots. Results: The energy share from UPFDs varied markedly across the 22 European countries included, ranging from 14 to 44%, being the lowest in Italy and Romania, while the highest in the UK and Sweden. An overall modest decrease (2–15%) in UPFDs consumption is observed over time, except for Finland, Spain and the UK reporting increases (3–9%). Fine bakery wares and soft drinks were most frequently ranked as the main contributor. Countries with a higher sugar intake reported also a higher energy share from UPFDs, as most clearly observed for UPF (r = 0.57, p value = 0.032 for men; and r = 0.53, p value = 0.061 for women). No associations with fibre intake or high BMI were observed. Conclusion: Population-level UPFDs consumption substantially varied across Europe, although main contributors are similar. UPFDs consumption was not observed to be associated with country-level burden of high BMI, despite being related to a higher total sugar intake. [ABSTRACT FROM AUTHOR]

Background: Baby‐led weaning (BLW), where infants self‐feed without the use of spoon‐feeding by a caregiver, continues to be a popular approach for starting solids. However, concerns remain amongst health professionals that infants using this method may not consume sufficient energy or nutrients from solid foods. Little research has examined how different weaning approaches shape dietary intake. The present study aimed to use a 3‐day weighed diet diary to measure estimated energy and nutrient intake in infants aged 6–12 months. Methods: Diet diaries were completed by 71 parents and analysed to compare estimated infant intake from milk and solid foods for those either following a BLW or traditional spoon‐feeding approach (TW). Intake was analysed for each weaning group in two age groups: 26–39 and 40–52 weeks, to account for different eating patterns at the start and end of the weaning process. Results: For the younger infants, significant differences in estimated energy intake were found, with TW infants consuming 285 kcal from solid foods compared with 120 kcal for BLW infants. Conversely, BLW infants consumed more calories and nutrients from breast or formula milk, consistent with a slower transition to solid foods. No differences were found in estimated intake amongst older infants, suggesting that BLW infants had 'caught up' with their spoon‐fed peers. Conclusions: Overall, few infants regardless of weaning group met recommended intake guidelines for energy (either over or under consuming) with many deficient in iron and zinc intake. The findings are important for those supporting parents through the transition to solid foods. Key points: At 6–9 months, infants following a baby‐led weaning (BLW) consumed less energy from solid foods compared to traditionally weaned (TW) infants with over three‐quarters of TW infants consuming more than World Health Organisation (WHO) guidelines. Infants following a BLW approach had a more gradual transition to solid foods than those following a TW approach more closely supporting WHO guidelines. However, some parents may need further support with respect to offering more solid food exposures. No differences were found in energy, macro‐ or micronutrient intake for infants aged 10–12 months for infants following BLW or TW approaches, suggesting a convergence of intake towards later infancy. Many infants, regardless of weaning approach, did not meet the recommended guidelines for iron or zinc intake, suggesting that there is a need to focus on promoting the intake of these micronutrients.

Introduction: Fermented foods have been consumed for millennia and commercially‐produced variants are now available in the food supply. The present study aimed to investigate the availability, cost, ingredients, nutritional content and on‐pack claims of commercially‐available fermented foods in the UK. Methods: All products from seven categories of commercially‐available fermented foods were systematically identified at eight national supermarket chains in the UK. Data were extracted from manufacturer and retailer websites and were compared between categories using a Kruskal–Wallis test and Fisher's exact test. Results: In total, 143 fermented foods were identified, with kombucha (41, 28.7%), kefir drinks (32, 22.4%), sauerkraut (22, 15.4%) and kefir yoghurts (21, 14.7%) being most common. The number of products sold at each retailer differed between categories (p = 0.016), and was greatest for kefir drink (median = 7.0, interquartile range [IQR] = 9.0), kombucha (median = 5.5, IQR = 11.5) and kefir yoghurts (median = 5.0, IQR = 8.5). Kombucha (£1.99 per serving) and kefir drinks (£1.26 per serving) were the most expensive fermented foods and sauerkraut (£0.66 per serving) and miso (£0.20 per serving) were the least expensive. Energy, fat, saturated fat, sugar, protein and salt content varied between fermented foods (p < 0.001). Nutrition claims were made on 72 (50.3%) products, the total number of cultures was labelled on 29 (20.3%), specific strains were named on 53 (37.1%) and bacteria‐related benefits were promoted on 39 (27.3%) products. Conclusions: Commercially‐produced fermented foods are widely available in the UK but are diverse in their cost, nutritional content, ingredients and use of on‐pack claims. Consumers should be aware of these variations given the limited evidence of functional benefits from controlled human trials. [ABSTRACT FROM AUTHOR]

Background: Non-melanoma skin cancer (NMSC) incidence has been dramatically increasing worldwide. Psoralen, a known photocarcinogen, is naturally abundant in citrus products, leading to the hypothesis that high citrus consumption may increase NMSC risk. Methods: We fitted age- and multivariable-adjusted logistic regression models to evaluate the association between citrus consumption and NMSC risk among 197,372 UKBB participants. A total of 9,613 NMSC cases were identified using International Classification of Disease 10 codes. Citrus consumption data were collected via five rounds of 24-hour recall questionnaires. Results: We found no association between high total citrus consumption and NMSC risk, although a slightly elevated NMSC risk was observed among participants who consumed >0 to half a serving of total citrus per day (OR [95% CI] = 1.08 [1.01-1.16]). There was no association between individual citrus products and NMSC risk. Conclusion: High citrus consumption was not associated with an increased risk of NMSC in our UKBB sample. Further studies are needed to clarify these associations. Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1952439. [ABSTRACT FROM AUTHOR]

Overweight and obesity is a global concern as a significant risk factor for non‐communicable diseases. Increased energy intake due to greater consumption of energy‐dense food or non‐alcoholic beverages high in fat, saturated fat, sugar or salt ('HFSS food') is the main explanation for population weight gain. The principal drivers underlying this consumption are the commercial determinants of health in the food chain, particularly the marketing of HFSS food. In the UK, some rules do regulate certain forms of HFSS food marketing (such as television and online advertising to children) and the government is considering strengthening these. However, although sports sponsorship by 'HFSS food businesses' (defined as a business preparing, cooking, storing, handling, distributing, supplying or selling food and whose products are primarily HFSS) is increasingly recognised as linked to HFSS food consumption, it has received little attention. This is all the more concerning in light of the recent proliferation of 'HFSS food businesses' and HFSS products partnering with sports organisations. Against this background, we hosted a workshop to focus on the relationship between health, nutrition and the sponsorship of sport and related marketing by 'HFSS food businesses' and to consider the implications for obesity prevention strategies in the UK and beyond. This innovative workshop capitalised on, and contributed to, ongoing efforts to conceptually unite existing research by bringing together an interdisciplinary team of experts providing unique and complementary perspectives on how to address sports sponsorship as one of the channels through which 'HFSS food businesses' contribute to poor nutrition and diet‐related diseases. This report summarises the structure, participants and discussions from the workshop; the existing evidence base; and the future research and policy opportunities we plan to pursue.

Background: Estimated food records (EFR) are a common dietary assessment method. This investigation aimed to; (1) define the reporting quality of the EFR, (2) characterise acute dietary intake and eating behaviours, (3) describe diet heritability.Methods: A total of 1974 one-day EFR were collected from 1858 participants in the TwinsUK cohort between 2012 and 2017. EFR were assessed using a six-point scoring system to determine reporting quality. The frequency and co-occurrence of food items was examined using word clouds and co-occurrence networks. The impact of eating behaviours on weight, BMI and nutrient intake were explored using mixed-effect linear regression models. Finally, diet heritability was estimated using ACE modelling.Results: We observed that 75% of EFR are of acceptable reporting quality (score > 5). Black tea and semi-skimmed milk were the most consumed items, on an individual basis (respectively 8.27, 6.25%) and paired (0.21%) as co-occurring items. Breakfast consumption had a significantly (p = 5.99 × 10- 7) greater impact on energy (kcal) (mean 1874.67 (±SD 532.42)) than skipping breakfast (1700.45 (±SD 620.98)), however only length of eating window was significantly associated with body weight (kg) (effect size 0.21 (±SD 0.10), p = 0.05) and BMI (effect size 0.08 (±SD 0.04), p = 0.04) after adjustment for relevant covariates. Lastly, we reported that both length of eating window (h2 = 33%, CI 0.24; 0.41), and breakfast consumption (h2 = 11%, CI 0.02; 0.21) were weakly heritable.Conclusions: EFR describing acute dietary intake allow for eating behaviour characterisation and can supplement habitual diet intake assessments. Novel findings of heritability warrant further investigation. [ABSTRACT FROM AUTHOR]

Purpose: To examine the associations of specific dietary fats with the risk of disabling hearing impairment in the UK Biobank study. Methods: This cohort study investigated 105,592 participants (47,308 men and 58,284 women) aged ≥ 40 years. Participants completed a minimum of one valid 24-h recall (Oxford Web-Q). Dietary intake of total fatty acids, polyunsaturated fatty acids (PUFA), saturated fatty acids (SFA), and monounsaturated fatty acids (MUFA) was assessed at baseline. Functional auditory capacity was measured with a digit triplet test (DTT), and disabling hearing impairment was defined as a speech reception threshold in noise > − 3.5 dB in any physical exam performed during the follow-up. Results: Over a median follow-up of 3.2 (SD: 2.1) years, 832 men and 872 women developed disabling hearing impairment. After adjustment for potential confounders, including lifestyles, exposure to high-intensity sounds, ototoxic medication and comorbidity, the hazard ratios (HRs), and 95% confidence interval (CI) of disabling hearing function, comparing extreme quintiles of intakes were 0.91 (0.71–1.17) for total fat, 1.09 (0.83–1.44) for PUFA, 0.85 (0.64–1.13) for SFA and 1.01 (0.74–1.36) for MUFA among men. Among women, HRs comparing extreme intakes were 0.98 (0.78–1.24) for total fat, 0.69 (0.53–0.91) for PUFA, 1.26 (0.96–1.65) for SFA, and 0.91 (0.68–1.23) for MUFA. Replacing 5% of energy intake from SFA with an equivalent energy from PUFA was associated with 25% risk reduction (HR: 0.75; 95% CI: 0.74–0.77) among women. Conclusions: PUFA intake was associated with decreased risk of disabling hearing function in women, but not in men. [ABSTRACT FROM AUTHOR]

Purpose: Early puberty is associated with adverse health outcomes. To identify potential modifiable factors for puberty timing, we examined the associations of prepubertal childhood macronutrient intakes with puberty timing in boys and girls. Methods: In the Avon Longitudinal Study of Parents and Children, macronutrient intakes at age 6 years were predicted using random intercepts linear regression models of dietary data at 3, 4, 7 (assessed by food frequency questionnaires) and 7.5 years (by 3-day food diaries). Timings of puberty onset (Tanner stage 2 genital or breast (B2) development) and puberty completion (voice breaking (VB) or menarche) were calculated from annual parental and child reports at 8–17 years. Age at peak height velocity (PHV) was derived from repeated height measurements at 5–20 years. Linear regression models were fit to estimate the associations of total energy (TEI) and macronutrient intakes (carbohydrate, fat, protein) with puberty timing traits, adjusting for maternal and infant characteristics. Results: Among 3811 boys, higher TEI, but no macronutrient, was associated with earlier VB. Among 3919 girls, higher TEI was associated with earlier ages at B2, PHV, and menarche. Higher protein intake but not carbohydrate or fat intake (in energy partition models) and substitution of dietary protein for carbohydrate (in nutrient density and residual models) was associated with earlier B2, PHV, and menarche in girls. Findings were not attenuated on additional adjustment for body fat percentage during adolescence. Conclusions: These findings suggest habitual total energy intakes in children, and protein intakes in girls, as potential modifiable determinants of puberty timing. [ABSTRACT FROM AUTHOR]

Background: Dietary guidelines for type 2 diabetes mellitus (T2DM) emphasise weight management and individualised total carbohydrate intake. Evidence on the most effective dietary patterns (DPs) for T2DM management is mixed, potentially leading to variations in the advice that dietitians provide. The present study aimed to explore dietitians' practice of DP advice provision to adults with T2DM, as well as understand their views when advising their patients on the DPs deemed effective for glycaemic management or recommended by current guidelines. Methods: Semi‐structured interviews were conducted with 12 UK‐registered dietitians, with experience in consulting adults with T2DM. Dietitians were asked for their views on five DPs recommended for glycaemic management of T2DM. Interview transcripts were analysed using deductive and inductive thematic analysis. Results: Nine themes were identified that draw attention to DP advice provision practices, the five DPs (low‐carbohydrate, low‐fat, low‐glycaemic index, Mediterranean diet and Dietary Approaches to Stop Hypertension diet), other DPs, the barriers and facilitators to DP advice provision and following this advice, and the factors affecting the provision of DP advice. Participants' current practice of DP advice provision to patients with T2DM was perceived to be individualised and patient‐centred. Participants discussed their current practice and perceptions of available evidence and how patients respond to advice on the DPs shown to be effective for glycaemic management. Several barriers to providing advice on specific DPs, including safety and compliance challenges, were identified. Participants also highlighted factors that would facilitate the provision of advice on specific DPs and would help patients to follow this advice, including social support, educational resources and more robust scientific evidence. Conclusions: The findings of the present study provide important insights regarding dietitians' views of promoting whole DPs to patients with T2DM. Emerged barriers and facilitators should be considered when developing future guidance for dietetic practice to support patients with following whole DPs for T2DM management. [ABSTRACT FROM AUTHOR]

We aimed to evaluate the association between eating context patterns and ultraprocessed food consumption at two main meal occasions in a representative sample of UK adolescents. Data were acquired from 4-d food records of adolescents aged 11–18 years, who participated in the 2014–2016 UK National Diet and Nutrition Survey (n 542). The eating context was assessed considering the location of the meal (lunch and dinner) occasion, the individuals present, whether the television was on and if the food was consumed at a table. Ultraprocessed foods were identified using the NOVA classification. Exploratory factor analysis was used to identify eating context patterns for lunch and dinner. Linear regression models adjusted for the covariates were utilised to test the association between eating context patterns and the proportion of total daily energy intake derived from ultraprocessed foods. Their contribution was about 67 % to energy intake. Three patterns were retained for lunch ('At school with friends', 'TV during family meal' and 'Out-of-home (no school)'), and three patterns were retained for dinner ('Watching TV alone in the bedroom', 'TV during family meal' and 'Out-of-home with friends'). At lunch, there was no significant association between any of the three patterns and ultraprocessed food consumption. At dinner, the patterns 'Watching TV alone in the bedroom' (coefficient: 4·95; 95 % CI 1·87, 8·03) and 'Out-of-home with friends' (coefficient: 3·13; 95 % CI 0·21, 6·14) were associated with higher consumption of ultraprocessed food. Our findings suggest a potential relationship between the immediate eating context and ultraprocessed food consumption by UK adolescents. [ABSTRACT FROM AUTHOR]

Purpose: Resistant dextrin (RD) supplementation has been shown to alter satiety, glycaemia, and body weight, in overweight Chinese men; however, there are limited data on its effects in other demographic groups. Here, we investigated the effects of RD on satiety in healthy adults living in the United Kingdom. Methods: 20 normal weight and 16 overweight adults completed this randomised controlled cross-over study. Either RD (14 g/day NUTRIOSE® FB06) or maltodextrin control was consumed in mid-morning and mid-afternoon preload beverages over a 28-day treatment period with crossover after a 28-day washout. During 10-h study visits (on days 1, 14, and 28 of each treatment period), satietogenic, glycaemic and anorectic hormonal responses to provided meals were assessed. Results: Chronic supplementation with RD was associated with higher fasted satiety scores at day 14 (P = 0.006) and day 28 (P = 0.040), compared to control. RD also increased satiety after the mid-morning intervention drink, but it was associated with a reduction in post-meal satiety following both the lunch and evening meals (P < 0.01). The glycaemic response to the mid-morning intervention drink (0–30 min) was attenuated following RD supplementation (P < 0.01). Whilst not a primary endpoint we also observed lower systolic blood pressure at day 14 (P = 0.035) and 28 (P = 0.030), compared to day 1, following RD supplementation in the normal weight group. Energy intake and anthropometrics were unaffected. Conclusions: RD supplementation modified satiety and glycaemic responses in this cohort, further studies are required to determine longer-term effects on body weight control and metabolic markers.

This paper provides an outline of a new research project, funded through UKRI's 'Transforming UK food systems' programme. The H3 project (Healthy soil, Healthy food, Healthy people) aims to transform the UK food system 'from the ground up', through an integrated programme of research at lab, farm, landscape, local, regional and national scales. This article introduces the H3 project with a particular emphasis on those parts of our work that have most direct relevance in terms of improving human diet and nutrition. Specifically, we seek to make early interventions in the food system through biofortification and other measures that reduce the need for costly interventions at later stages. Focusing on low‐income populations and using a 'health by stealth' approach, we also seek to increase fibre consumption among the UK population by reformulating foods that are already an established part of people's diet. The paper concludes by assessing the likely impact of these interventions and the significance we attach to working with stakeholders in business, government and civil society.

Background Consumption of unhealthy foods may have changed during the COVID-19 pandemic. This study explored how dietary fat intake was impacted in a sample of the UK public who were social distancing during the COVID-19 pandemic. Methods Data were collected from a UK COVID-19 online survey. Fat intake was measured using the Dietary Instrument for Nutrition Education questionnaire. Anxiety and depressive symptoms were assessed using Becks' Anxiety and Depression Inventories, while the short-form Warwick-Edinburgh Mental Well-being Scale assessed mental well-being. Differences between individuals who increased versus decreased fat intake were explored using chi-square or independent sample t -tests. Association between fat intake and mental health was explored using adjusted linear regression models. Results Eight hundred and eighty-seven adults were included. Approximately, 34% recorded medium-to-high levels of fat consumption during social distancing. Around 48% reported decreased fat intake during social distancing compared to usual levels, while 41.3% documented increased fat intake. Fat intake was not significantly associated (P  > 0.05) with any measures of mental health. Conclusions A higher proportion of a sample of UK adults social distancing during the COVID-19 pandemic recorded decreased fat intake when compared to levels prior to social distancing. There appeared to be no associations between fat intake and mental health. [ABSTRACT FROM AUTHOR]

Background Both diet and familial factors have a major role in the development of cardiovascular disease (CVD). However, it remains unclear whether familial predisposition to CVD modifies the association between dietary factors and CVD. Objectives The aim was to assess whether the association between diet and CVD varies with familial predisposition to CVD. Methods In this prospective cohort of the UK Biobank, 462,155 CVD-free participants were included in 2006–2010 and followed for CVD incidence until 2020. Food intake was measured using a short food-frequency questionnaire. Familial predisposition was measured by self-reported family history of CVD and by polygenic risk score (PRS) for CVD based on summary statistics of independent genome-wide association studies. Results During a median follow-up of 11.2 y, 46,164 incident CVD cases were identified. A moderately higher risk of CVD was associated with more frequent processed-meat consumption, with an adjusted HR of 1.07 (95% CI: 1.03, 1.11; highest vs. lowest level). Conversely, intakes of fish, cheese, vegetables, and fruit were each associated with reduced CVD risk [HR (95% CI): 0.92 (0.89, 0.96), 0.90 (0.86, 0.94), 0.98 (0.95, 1.00), and 0.93 (0.89, 0.96), respectively]. Stratification analyses by family history of CVD and by PRS for CVD revealed an inverse association between CVD and intakes of fish and cheese, for both subgroups with and without a familial predisposition to CVD. Notably, while the association between processed-meat intake and CVD was restricted to individuals with a familial predisposition to CVD [e.g. HR: 1.11 (1.05, 1.16) and 1.03 (0.97, 1.10) for with and without a family history, respectively, P- interaction < 0.001], the risk reduction of CVD associated with vegetable and fruit intake was only noted among participants without a CVD familial predisposition [e.g. HR for fruit consumption: 1.00 (0.97, 1.03) and 0.91 (0.87, 0.95), respectively, P  < 0.001]. Conclusions Familial factors modify the association between diet and CVD, underscoring the need for personalized dietary guidelines for CVD prevention. [ABSTRACT FROM AUTHOR]

Background: Countries around the world are putting in place sugar reformulation targets for packaged foods to reduce excess sugar consumption. The Australian government released its voluntary sugar reformulation targets for nine food categories in 2020. We estimated the potential impact of these targets on household sugar purchases and examined differences by income. For comparison, we also modelled the potential impact of the UK sugar reduction targets on per capita sugar purchases as the UK has one of the most comprehensive sugar reduction strategies in the world. Methods: Grocery purchase data from a nationally representative consumer panel (n=7,188) in Australia was linked with a large database (FoodSwitch) with product-specific sugar content information for packaged foods (n=25,261); both datasets were collected in 2018. Potential reductions in per capita sugar purchases were calculated overall and by food category. Differences in sugar reduction across income level were assessed by analysis of variance. Results: In 2018, the total sugar acquired from packaged food and beverage purchases consumed at-home was 56.1 g/day per capita. Australia's voluntary reformulation targets for sugar covered 2,471/25,261 (9.8%) unique products in the FoodSwitch dataset. Under the scenario that all food companies adhered to the voluntary targets, sugar purchases were estimated to be reduced by 0.9 g/day per capita, which represents a 1.5% reduction in sugar purchased from packaged foods. However, if Australia adopted the UK targets, over twice as many products would be covered (n=4,667), and this would result in a more than four times greater reduction in sugar purchases (4.1 g/day per capita). It was also estimated that if all food companies complied with Australia's voluntary sugar targets, reductions to sugar would be slightly greater in low-income households compared with high-income households by 0.3 g/day (95%CI 0.2 - 0.4 g/day, p<0.001). Conclusions: Sugar-reduction policies have the potential to substantially reduce population sugar consumption and may help to reduce health inequalities related to excess sugar consumption. However, the current reformulation targets in Australia are estimated to achieve only a small reduction to sugar intakes, particularly in comparison to the UK's sugar reduction program.

Purpose: The Oxford WebQ is a web-based 24-h dietary assessment method which has been used in UK Biobank and other large prospective studies. The food composition table used to calculate nutrient intakes has recently been replaced with the UK Nutrient Databank, which has food composition data closer in time to when participants completed the questionnaire, and new dietary variables were incorporated. Here we describe the updated version of the Oxford WebQ questionnaire nutrient calculation, and compare nutrient intakes with the previous version used. Methods: 207,144 UK Biobank participants completed ≥ 1 Oxford WebQs, and means and standard deviations of nutrient intakes were averaged for all completed 24-h dietary assessments. Spearman correlations and weighted kappa statistics were used to compare the re-classification and agreement of nutrient intakes between the two versions. Results: 35 new nutrients were incorporated in the updated version. Compared to the previous version, most nutrients were very similar in the updated version except for a few nutrients which showed a difference of > 10%: lower with the new version for trans-fat (− 20%), and vitamin C (− 15%), but higher for retinol (+ 42%), vitamin D (+ 26%) and vitamin E (+ 20%). Most participants were in the same (> 60%) or adjacent (> 90%) quintile of intake for the two versions. Except for trans-fat (r = 0.58, κ = 0.42), very high correlations were found between the nutrients calculated using the two versions (r > 0.79 and κ > 0.60). Conclusion: Small absolute differences in nutrient intakes were observed between the two versions, and the ranking of individuals was minimally affected, except for trans-fat. [ABSTRACT FROM AUTHOR]

Background: Preterm formula milk (FM) is often prepared in advance, potentially affecting nutritional quality. Long‐chain polyunsaturated fatty acids (LCPUFAs), important for brain and immune system function, are prone to lipid peroxidation, which correlates with comorbidities of prematurity. The effects of clinical storage practices on LCPUFA content and lipid peroxidation of preterm FM were investigated. Methods: UK liquid and powder preterm FM (2017) (from two manufacturers) were subjected to routine storage conditions (liquid: refrigeration ≤10 h; powder: weekly preparation in accordance with the manufacturer's instructions and refrigeration ≤24 h for 4 weeks). LCPUFA content, thiobarbituric acid reactive substances and 4‐hydroxy‐2‐nonenal (HNE) content were analysed. Results: Storage did not significantly decrease LCPUFA content. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition recommended LCPUFA intake, whereas in utero accretion rates could not be achieved with both FM brands (liquid and powder). Lipid peroxidation was evident on opening, with 6× higher levels in powder. No effect of ≤10‐h refrigeration on peroxidation was seen in liquid FM. In powder FM, it increased over refrigeration (HNE opening: 6.5–9.7 µg mL–1 versus day 28, 24 h: 16.6–36.5 µg mL–1) with a significant interaction between storage time and refrigeration (P = 0.015), with higher HNE at 4 h on days 0, 7, 14 and 21 (all P < 0.05). Conclusions: The results suggest that preterm FM and storage conditions do not support in utero accretion rates for LCPUFAs. Although the results suggest different susceptibility of liquid and powder FM to peroxidation upon refrigeration, they are too preliminary to make specific recommendations. We suggest minimising storage time of fresh and prepared powder FM, wherever possible. [ABSTRACT FROM AUTHOR]

Background: Food insecurity in UK households is a substantial and growing concern. The present study identified those at risk of food insecurity and explored the relationship between food security and fruit and vegetable consumption. Methods: Data were examined from the Food and You survey (2016) for a large representative sample (n = 3118) living in England, Wales and Northern Ireland. A 'Food Security Score' and a 'Food Changes Score' (relating to financially driven changes to food habits) were compiled and relationships with fruit and vegetable consumption were examined. Results: The prevalence of marginal, low and very low food security was 12.6%, 5.4% and 2.8%, respectively. Significant correlations were observed between food security and fruit and vegetable consumption. Food security and food changes, independently, were significant predictors for fruit and vegetable consumption. With every unit increment in the Food Security Score (i.e., more food insecure), an 11% decrease in the odds of being a high fruit and vegetable consumer was evident. Likewise, the odds of being a high fruit and vegetable consumer decreases by 5% with every increment in the financially driven Food Changes Score. Conclusions: A notable proportion (more than one‐fifth) experienced marginal, low or very low food security. Food insecurity and financially driven food changes were accompanied by decreases in the odds of being a high fruit and vegetable consumer. Findings underline the potential consequences of food insecurity, and point to further work aiming to examine other dietary implications, as well as strategies to mitigate against food insecurity and its detriment.

Background: Overconsumption of energy from food is a major contributor to the high rates of overweight and obesity in many populations. There is growing evidence that interventions that target the food environment may be effective at reducing energy intake. The current study aimed to estimate the effect of decreasing the proportion of higher energy (kcal) foods, with and without reducing portion size, on energy purchased in worksite cafeterias.Methods and Findings: This stepped-wedge randomised controlled trial (RCT) evaluated 2 interventions: (i) availability: replacing higher energy products with lower energy products; and (ii) size: reducing the portion size of higher energy products. A total of 19 cafeterias were randomised to the order in which they introduced the 2 interventions. Availability was implemented first and maintained. Size was added to the availability intervention. Intervention categories included main meals, sides, cold drinks, snacks, and desserts. The study setting was worksite cafeterias located in distribution centres for a major United Kingdom supermarket and lasted for 25 weeks (May to November 2019). These cafeterias were used by 20,327 employees, mainly (96%) in manual occupations. The primary outcome was total energy (kcal) purchased from intervention categories per day. The secondary outcomes were energy (kcal) purchased from nonintervention categories per day, total energy purchased per day, and revenue. Regression models showed an overall reduction in energy purchased from intervention categories of -4.8% (95% CI -7.0% to -2.7%), p < 0.001 during the availability intervention period and a reduction of -11.5% (95% CI -13.7% to -9.3%), p < 0.001 during the availability plus size intervention period, relative to the baseline. There was a reduction in energy purchased of -6.6% (95% CI -7.9% to -5.4%), p < 0.001 during the availability plus size period, relative to availability alone. Study limitations include using energy purchased as the primary outcome (and not energy consumed) and the availability only of transaction-level sales data per site (and not individual-level data).Conclusions: Decreasing the proportion of higher energy foods in cafeterias reduced the energy purchased. Decreasing portion sizes reduced this further. These interventions, particularly in combination, may be effective as part of broader strategies to reduce overconsumption of energy from food in out-of-home settings.Trial Registration: ISRCTN registry ISRCTN87225572.

Purpose: We tested the acute effect of breakfast (ready-to-eat-cereal [RTEC] and milk) versus (vs.) no breakfast on cognitive function and subjective state in adolescents. Methods: Healthy adolescents (n = 234) aged 11–13 years were recruited to take part in this school-based, acute, randomised, controlled, parallel groups trial with two interventions; Breakfast or No Breakfast. The breakfast intervention consisted of ad libitum intake of RTEC (up to 70 g) with milk (up to 300 ml) administered in a naturalistic school breakfast programme environment. Cognitive function was assessed at baseline and + 70 and + 215 min post-intervention in a group-testing situation, similar to a school classroom context. The CANTAB test battery included: Simple Reaction Time (SRT), 5-Choice Reaction Time (5-CRT), Rapid Visual Information Processing (RVIP), and Paired Associates Learning (PAL; primary outcome). Data collection commenced January 2011 and ended May 2011. This trial was retrospectively registered at www.clinicaltrials.gov as NCT03979027 on 07/06/2019. Results: A significant effect of the intervention (CMH[1] = 7.29, p < 0.01) was found for the number of levels achieved on the PAL task. A significant difference between interventions was found when baseline performance reached level 2 (JT, z = 2.58, p < 0.01), such that 100% of participants in the breakfast intervention reached the maximum level 4 but only 41.7% of those in the no breakfast intervention reached level 4. A significant baseline*intervention interaction (F[1,202] = 6.95, p < 0.01) was found for total errors made on the PAL task, indicating that participants who made above-average errors at baseline reduced the total number of errors made at subsequent test sessions following breakfast consumption whilst those in the no breakfast intervention did not. There was a positive effect of breakfast on reaction time and visual-sustained attention. The results also demonstrated interactions of intervention with baseline cognitive performance, such that breakfast conferred a greater advantage for performance when baseline performance was poorer. Conclusion: Consuming breakfast has a positive acute effect on cognition in adolescents. [ABSTRACT FROM AUTHOR]

Purpose: To determine the association between red meat (RM), processed red meat (PRM) and total red and processed red meat (TRPRM) consumption on nutritional adequacy and markers of health and cardio-metabolic diseases in British adults. Methods: In this cross-sectional study of adults (19–64 y) from the National Diet and Nutrition Survey (NDNS) (n = 1758), RM and PRM consumption were assessed from 4 day estimated food diaries. Anthropometric measures, blood pressure (BP), pulse pressure (PP), plasma glucose, HbA1c, C-reactive protein, TAG, TC, LDL-C and HDL-C from the NDNS were used. Results: 43% of adults (men 57% and women 31%) consumed more than the 70 g/d TRPRM guidelines. Fewer adults in the highest tertile of TRPRM intake were below lower reference nutrient intakes (LRNIs), particularly for zinc and iron, respectively. In model 3 (controlled for age, energy intake, socioeconomic classification, number of daily cigarettes, BMI, dietary factors), higher RM consumption was associated with being significantly taller (model 3: P-ANCOVA = 0.006; P-T3/T1 = 0.0004) in men and lower diastolic BP (model 3: P-ANCOVA = 0.004; P-T3/T2 = 0.002) in women. Higher PRM in men was associated with significantly higher plasma ferritin concentration (model 3: P-ANCOVA = 0.0001; P-T2/T1 = 0.0001), being taller (P-ANCOVA = 0.019; P-T1/T2 = 0.047, T1/T3 = 0.044), increased body weight (model 3: P-ANCOVA = 0.001; P-T1/T3 = 0.0001), BMI (model 3: P-ANCOVA = 0.007; P-T1/T3 = 0.006) and smaller hip circumference (model 3: P-ANCOVA = 0.006; P-T3/T1 = 0.024; P-T2/T1 = 0.013) and in women significantly higher TC (model 3: P-ANCOVA = 0.020; P-T3/T2 = 0.016), LDL-C (P-ANCOVA = 0.030; P-T3/T2 = 0.025), HbA1c (model 3: P-ANCOVA = 0.0001; P-T2/T1 = 0.001; P-T3/T2 = 0.001) and higher PP (model 3: P-ANCOVA = 0.022; P-T3/T1 = 0.021). Higher PRM consumption was associated with significantly higher BMI and hip circumference in men, and higher TC, LDL-C, HbA1c and PP in women, which was not observed for RM consumption.

Objective: To examine awareness and recall of healthy eating public education campaigns in five countries.Design: Data were cross-sectional and collected as part of the 2018 International Food Policy Study. Respondents were asked whether they had seen government healthy eating campaigns in the past year; if yes (awareness), they were asked to describe the campaign. Open-ended descriptions were coded to indicate recall of specific campaigns. Logistic models regressed awareness of healthy eating campaigns on participant country, age, sex, ethnicity, education, income adequacy and BMI. Analyses were also stratified by country.Setting: Online surveys.Participants: Participants were Nielsen panelists aged ≥18 years in Australia, Canada, Mexico, UK and the USA (n 22 463).Results: Odds of campaign awareness were higher in Mexico (50·9 %) than UK (18·2 %), Australia (17·9 %), the USA (13·0 %) and Canada (10·2 %) (P < 0·001). Awareness was also higher in UK and Australia v. Canada and the USA, and the USA v. Canada (P < 0·001). Overall, awareness was higher among males v. females and respondents with medium or high v. low education (P < 0·001 for all). Similar results were found in stratified models, although no sex difference was observed in Australia or UK (P > 0·05), and age was associated with campaign awareness in UK (P < 0·001). Common keywords in all countries included sugar/sugary drinks, fruits and vegetables, and physical activity. The top five campaigns recalled were Chécate, mídete, muévete (Mexico), PrevenIMSS (Mexico), Change4Life (UK), LiveLighter® (Australia), and Actívate, Vive Mejor (Mexico).Conclusions: In Mexico, UK and Australia, comprehensive campaigns to promote healthy lifestyles appear to have achieved broad, population-level reach.

Objective: The aim of the present study was to develop and validate a vitamin D FFQ for assessment of dietary vitamin D intake in healthy adults in England, UK.Design: The current study assessed the agreement between a four-day food diary (4 d-FD) and a new vitamin D FFQ to measure dietary intake of vitamin D. Dietary intake was estimated using Nutritics dietary analysis software, and Spearman's and Bland-Altman tests were utilised to assess correlation and agreement, respectively. Participants also provided a blood sample for plasma analysis of vitamin D concentrations.Setting: Home setting.Participants: Fifty participants were recruited to the study from the University of Chester and vicinity.Results: Results showed a strong correlation between vitamin D intake recorded by the FFQ and the 4 d-FD (r = 0·609; P < 0·0001) within 95 % limits of agreement. Furthermore, a significant correlation between plasma 25(OH)D concentrations and vitamin D intake measured by the FFQ (r = 0·290, P = 0·041) and the 4 d-FD (r = 0·360, P = 0·01) was observed.Conclusion: Our analysis suggests this FFQ is a useful and rapid tool for researchers and health professionals to assess vitamin D dietary intakes in healthy adults in the UK.

Background: Children from Black and South Asian ethnic groups are at risk for childhood obesity in the United Kingdom. To inform local action for childhood obesity prevention, it is crucial to explore the basis of ethnic disparities and consider the perspectives of children. This study aimed to understand cultural and contextual factors influencing childhood obesity in an ethnically diverse population using child‐centred methodology. Methods: 'Draw, write and tell' interviews were held with children aged 9–10 years in Coventry, an urban, multi‐ethnic city in the United Kingdom. Data were analysed thematically using framework analysis. Results: Twenty‐six children participated (85% from Black or minority ethnic groups). Children's perspectives revealed universal themes around health, diet, physical activity and weight and highlighted issues specific to ethnic groups and those living in deprived areas. An underlying feature was weight‐based stigmatization and group stereotyping, and an emphasis on internal factors as the cause of obesity. Children described some experiences of social disadvantage but did not regard these as a barrier to being physically active. Children identified cultural or religious practices or experiences of migration that influenced diet and physical activity. Conclusions: These findings allow a broad range of children's perspectives to inform future intervention design. In addition, the study was able to identify the many similarities and small amount of diversity in children's perspectives across ethnic groups. [ABSTRACT FROM AUTHOR]

Vitamin D deficiency is a significant public health issue in the UK with almost one in five adults having poor vitamin D status and most people failing to meet the Reference Nutrient Intake of 10 µg/day. There is an urgent need to address poor population vitamin D status through the development of food‐based strategies. Eggs can be enriched with vitamin D through manipulating vitamin D content in hens' feed. The Sunshine Eggs project was launched in 2015 through Innovate UK funding and brought together Noble Foods Ltd, DSM Nutritional Products Ltd and Newcastle University. The research demonstrated that feeding flocks of commercial hens up to 75 µg of 25‐D/kg (25‐hydroxyvitamin D3 via Rovimix® Hy‐D®) of feed for 6 weeks improved egg total vitamin D content by 40%. These results informed the reformulation of the UK's leading free‐range egg brand 'Happy Egg' in October 2018, offering vitamin D–enriched eggs to the consumer. This article outlines the aims of a second Innovate UK‐funded Sunshine Eggs 2 project, which seeks to maximise the commercial potential of vitamin D–enriched eggs through several objectives. These relate to understanding (1) how storage/cooking methods affect egg vitamin D content; (2) whether enriched egg consumption improves vitamin D status in a human intervention trial; (3) consumer attitudes towards enriched eggs; and (4) market research to identify commercial opportunities for enriched eggs. The project seeks to drive fundamental impact across academic, commercial and public health nutrition sectors, in helping to offer viable vitamin D–enriched foods for UK consumers.

Obesity and diet‐related chronic diseases remain a serious public health concern across the globe. As part of an integrated package of policies to tackle obesity, many countries use front‐of‐pack nutrition labelling (FOPNL), which can provide at‐a‐glance information to help consumers make healthier food choices. The UK government has recently run a consultation (July 2020–October 2020) on FOPNL to gather views and evidence on the current 'multiple traffic lights' (MTL) label scheme, and to compare other FOPNL schemes (such as the Chilean Warning and Nutri‐Score labels) in respect of their impact on consumer and industry behaviour. To identify and explore the strengths and limitations of different FOPNL systems, the British Nutrition Foundation hosted a virtual roundtable event with a wide range of stakeholders in October 2020. The ensuing discussions considered the effectiveness of FOPNL in guiding food purchases and healthier eating choices and in driving product reformulation; as well as the potential advantages, disadvantages, opportunities and challenges of different systems including MTL and Nutri‐Score. This report describes some of the key points emerging from the discussions. [ABSTRACT FROM AUTHOR]

A variety of materials offering healthy eating advice have been produced in the United Kingdom to encourage people to eat well and avoid diet-related health issues. By applying a Foucauldian discourse analysis, this research aimed to uncover the discourses used in six healthy eating texts (two state-produced and four commercial texts), how people positioned themselves in relation to these discourses, and the power relations between institutions and the U.K. public. Ten discourses including scientific, thermodynamics, natural, family/caring, emotional, medical, and moral discourses were uncovered and offered up subject positions in relation to moral citizenship and personal responsibility. Through the use of biopower, foods appeared to be categorized as "good" or "bad" foods in which bad foods were considered to be risky to health due to their nutritional composition. Most texts assumed people have the agency to follow the advice provided and failed to consider the readers' personal contexts. [ABSTRACT FROM AUTHOR]

Background: During the global COVID‐19 pandemic, UK dietitians have delivered the best care to help patients recover from the infection. The present study examined the development and evaluation of care pathways to manage nutritional care of patients following COVID‐19 infection prior to and after discharge. Methods: Registered UK dietitians completed an online questionnaire comprising 26 questions about the development of a pathway, its use, evaluation and training needs. Results: Of 57 responses from organisations, 37 (65%) were involved in the planning/management of nutritional care. Only 19 responses had a new or adapted COVID‐19 pathway. Of these, 74% reported involvement of dietetic services, 47% reported > 1 eligibility criteria for pathway inclusion and 53% accepted all positive or suspected cases. All respondents used nutritional screening, first‐line dietary advice (food first) and referral for further advice and monitoring. Weight and food intake were the most used outcome measure. All pathways addressed symptoms related to nutrition, with the most common being weight loss with poor appetite, not being hungry and skipping meals in 84% of pathways. Over half of respondents (54%) planned to evaluate their pathway and 83% reported that they were 'very or reasonably confident' in their team's nutritional management of COVID‐19. Less than half (42%) reported on training needs. Conclusions: Despite challenges encountered, pathways were developed and implemented. Dietitians had adapted to new ways of working to manage nutritional care in patients prior to and after discharge from hospital following COVID‐19 infection. Further work is needed to develop strategies for evaluation of their impact. [ABSTRACT FROM AUTHOR]

Background Fruit and vegetable consumption in the United Kingdom is currently well below recommended levels, with a significant associated public health burden. The United Kingdom has committed to reducing its carbon emissions to net zero by 2050, and this transition will require shifts towards plant-based diets. Objective The aim was to quantify the health effects, environmental footprints, and cost associated with 4 different pathways to meeting the United Kingdom's "5-a-day" recommendation for fruit and vegetable consumption. Methods Dietary data based on 18,006 food diaries from 4528 individuals participating in the UK National Diet and Nutrition Survey (2012/13–2016/17) constituted the baseline diet. Linear programming was used to model the hypothetical adoption of the 5-a-day (400 g) recommendation, which was assessed according to 4 pathways differing in their prioritization of fruits versus vegetables and UK-produced versus imported varieties. Increases in fruit and vegetable consumption were substituted for consumption of sweet snacks and meat, respectively. Changes in life expectancy were assessed using the IOMLIFET life table model. Greenhouse gas emissions (GHGEs), blue water footprint (WF), and total diet cost were quantified for each 5-a-day diet. Results Achieving the 5-a-day target in the United Kingdom could increase average life expectancy at birth by 7–8 mo and reduce diet-related GHGEs by 6.1 to 12.2 Mt carbon dioxide equivalents/y; blue WFs would change by −0.14 to +0.07 km3/y. Greater reductions in GHGEs were achieved by prioritizing increased vegetable consumption over fruit, whereas the greatest reduction in WF was obtained by prioritizing vegetable varieties produced in the United Kingdom. All consumption pathways increased diet cost (£0.34–£0.46/d) Conclusions Benefits to both population and environmental health could be expected from consumption pathways that meet the United Kingdom's 5-a-day target for fruit and vegetables. Our analysis identifies cross-sectoral trade-offs and opportunities for national policy to promote fruit and vegetable consumption in the United Kingdom. [ABSTRACT FROM AUTHOR]

Children's vegetable consumption is generally below national recommendations in the UK. This study examined predictors of vegetable intake by children aged 1·5–18 years using counts and portion sizes derived from 4-d UK National Diet and Nutrition Survey food diaries. Data from 6548 children were examined using linear and logit multilevel models. Specifically, we examined whether demographic variables predicted vegetable consumption, whether environmental context influenced portion sizes of vegetables consumed and which food groups predicted the presence (or absence) of vegetables at an eating occasion (EO). Larger average daily intake of vegetables (g) was predicted by age, ethnicity, equivalised income, variety of vegetables eaten and average energy intake per d (R2 0·549). At a single EO, vegetables were consumed in larger portion sizes at home, with family members and at evening mealtimes (Conditional R2 0·308). Within EO, certain configurations of food groups such as carbohydrates and protein predicted higher odds of vegetables being present (OR 12·85, 95 % CI 9·42, 17·54), whereas foods high in fats, sugars and salt predicted a lower likelihood of vegetable presence (OR 0·03, 95 % CI 0·02, 0·04). Vegetables were rarely eaten alone without other food groups. These findings demonstrate that only one portion of vegetables was eaten per d (median) and this was consumed at a single EO, therefore falling below recommendations. Future research should investigate ways to encourage vegetable intake at times when vegetables are not regularly eaten, such as for breakfast and as snacks, whilst considering which other, potentially competing, foods are presented alongside vegetables.

We aimed to investigate the associations of poor oral health cross-sectionally with diet quality and intake in older people. We also examined whether change in diet quality is associated with oral health problems. Data from the British Regional Heart Study (BRHS) comprising British males aged 71–92 years and the Health, Aging and Body Composition (HABC) Study comprising American males and females aged 71–80 years were used. Dental data included tooth loss, periodontal disease, dry mouth and self-rated oral health. Dietary data included diet quality (based on Elderly Dietary Index (BRHS) and Healthy Eating Score (HABC Study)) and several nutrients. In the BRHS, change in diet quality over 10 years (1998–2000 to 2010–2012) was also assessed. In the BRHS, tooth loss, fair/poor self-rated oral health and accumulation of oral health problems were associated with poor diet quality, after adjustment. Similar associations were reported for high intake of processed meat. Poor oral health was associated with the top quartile of percentage of energy content from saturated fat (self-rated oral health, OR 1·34, 95 % CI 1·02, 1·77). In the HABC Study, no significant associations were observed for diet quality after adjustment. Periodontal disease was associated with the top quartile of percentage of energy content from saturated fat (OR 1·48, 95 % CI 1·09, 2·01). In the BRHS, persistent low diet quality was associated with higher risk of tooth loss and accumulation of oral health problems. Older individuals with oral health problems had poorer diets and consumed fewer nutrient-rich foods. Persistent poor diet quality was associated with oral health problems later in life.

Aim: This study aimed to determine the causal association between salt added to food and body mass index (BMI) by integrating a summary‐level genome‐wide association study (GWAS) data. Methods: We performed two‐sample Mendelian randomisation (MR) analyses using summary statistics of GWAS. Inverse‐variance weighted (IVW), maximum likelihood estimation, and random effect model were used to analyse the effect of salt added to food on BMI. A bidirectional MR analysis with BMI as the exposure and salt added to food as the outcome was also performed. Results: The single nucleotide polymorphisms (SNPs) were selected from the UK Biobank (n = 462 630) and a meta‐analysis of 322 154 European‐descent individuals. The IVW method estimate indicated that salt added to food was positively associated with BMI (β = 0.1416, SE = 0.0576, P =.0139). Results from maximum likelihood estimation (β = 0.1476, SE = 0.0363, P <.0001) and the random effect model (β = 0.1411, SE = 0.0572, P =.0137) were consistent with the IVW. Bidirectional MR analysis suggested that BMI did not causally affect salt added to food. Conclusion: Our results provided qualitative evidence supporting a causal relationship between salt intake and BMI. [ABSTRACT FROM AUTHOR]

Individuals of South Asian ethnicity have an increased risk for obesity and related diseases. Foods available in the home during the first 1000 days (conception to 24 months old) are an important determinant of diet, yet no study has examined the association of early‐life home food availability (HFA) with later diet and obesity risk in South Asian households. We examined whether obesogenic HFA at 18 months of age is associated with dietary intake and body mass index (BMI) at 36 months of age in low‐income Pakistani and White households in the United Kingdom. In this prospective birth cohort study (Born in Bradford 1000), follow‐up assessments occurred at 18 (n = 1032) and 36 (n = 986) months of age. Variety and quantity of snack foods and sugar‐sweetened beverages (SSBs) in the home and consumed were measured using the HFA Inventory Checklist and food frequency questionnaires, respectively. BMI was calculated using measured length/height and weight. Multinomial logistic regression models examined associations between HFA and tertiles of dietary intake, and multivariable linear regression models assessed associations between HFA and BMI. Pakistani households had a greater variety and quantity of snack foods and SSBs available compared with White households. Variety and quantity of snack foods and SSBs in the home at 18 months were positively associated with children's intake of these items at 36 months, but associations between HFA and BMI were null. Reducing obesogenic HFA during the first 1000 days may promote the development of more healthful diets, though this may not be associated with lower obesity risk during toddlerhood.

Background Worldwide, the prevalence of dementia is increasing and diet as a modifiable factor could play a role. Meat consumption has been cross-sectionally associated with dementia risk, but specific amounts and types related to risk of incident dementia remain poorly understood. Objective We aimed to investigate associations between meat consumption and risk of incident dementia in the UK Biobank cohort. Methods Meat consumption was estimated using a short dietary questionnaire at recruitment and repeated 24-h dietary assessments. Incident all-cause dementia comprising Alzheimer disease (AD) and vascular dementia (VD) was identified by electronic linkages to hospital and mortality records. HRs for each meat type in relation to each dementia outcome were estimated in Cox proportional hazard models. Interactions between meat consumption and the apolipoprotein E (APOE) ε4 allele were additionally explored. Results Among 493,888 participants included, 2896 incident cases of all-cause dementia, 1006 cases of AD, and 490 cases of VD were identified, with mean ± SD follow-up of 8 ± 1.1 y. Each additional 25 g/day intake of processed meat was associated with increased risks of incident all-cause dementia (HR: 1.44; 95% CI: 1.24, 1.67; P -trend < 0.001) and AD (HR: 1.52; 95% CI: 1.18, 1.96; P -trend = 0.001). In contrast, a 50-g/d increment in unprocessed red meat intake was associated with reduced risks of all-cause dementia (HR: 0.81; 95% CI: 0.69, 0.95; P -trend = 0.011) and AD (HR: 0.70; 95% CI: 0.53, 0.92; P -trend = 0.009). The linear trend was not significant for unprocessed poultry and total meat. Regarding incident VD, there were no statistically significant linear trends identified, although for processed meat, higher consumption categories were associated with increased risks. The APOE ε4 allele increased dementia risk by 3 to 6 times but did not modify the associations with diet significantly. Conclusion These findings highlight processed-meat consumption as a potential risk factor for incident dementia, independent of the APOE ε4 allele. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to examine the associations between ultra-processed food consumption and risk of obesity among UK adults. Methods: Participants aged 40–69 years at recruitment in the UK Biobank (2006–2019) with dietary intakes collected using 24-h recall and repeated measures of adiposity––body mass index (BMI), waist circumference (WC) and percentage of body fat (% BF)––were included (N = 22,659; median follow-up: 5 years). Ultra-processed foods were identified using the NOVA classification and their consumption was expressed as a percentage of total energy intake. Multivariable Cox proportional hazards regression models were used to estimate hazard ratios (HR) of several indicators of obesity according to ultra-processed food consumption. Models were adjusted for sociodemographic and lifestyle characteristics. Results: 947 incident cases of overall obesity (BMI ≥ 30 kg/m2) and 1900 incident cases of abdominal obesity (men: WC ≥ 102 cm, women: WC ≥ 88 cm) were identified during follow-up. Participants in the highest quartile of ultra-processed food consumption had significantly higher risk of developing overall obesity (HR 1.79; 95% CI 1.06─3.03) and abdominal obesity (HR 1.30; 95% CI 1.14─1.48). They had higher risk of experiencing a ≥ 5% increase in BMI (HR 1.31; 95% CI 1.20─1.43), WC (HR 1.35; 95% CI 1.25─1.45) and %BF (HR 1.14; 95% CI 1.03─1.25), than those in the lowest quartile of consumption. Conclusions: Our findings provide evidence that higher consumption of ultra-processed food is strongly associated with a higher risk of multiple indicators of obesity in the UK adult population. Policy makers should consider actions that promote consumption of fresh or minimally processed foods and reduce consumption of ultra-processed foods. [ABSTRACT FROM AUTHOR]

Aim: To describe variation in the initial management of children presenting to Emergency Departments (ED) with coins lodged in the oesophagus. To determine the usage of hand-held metal detectors (HHMDs) in EDs, including their role in clinical decision-making, and training in their use.Methods: Online multicentre cross-sectional survey of EDs in the UK and Ireland, with results described using descriptive statistics.Results: Fifty-five (90%) of 61 sites responded. The two main strategies described for lodged oesophageal coins were endoscopic removal or observation with reassessment, dependent on location. For coins in the proximal third of the oesophagus 43/55 (78.2%) referred for endoscopic removal, 6/55 (10.9%) observed and the remaining 10.9% used a variety of methods, including: Foley catheter removal with fluoroscopy, blind Foley catheter removal, referral to paediatric surgery/ENT. Thirty (55%) of 55 used HHMDs, 21/30 (70%) had guidelines for their use, and 3/30 (10%) provided formal training. Twenty (67%) of 30 used the xiphisternum as the anatomical cut-off for assuming safe passage of metallic foreign bodies (FB) beyond the lower oesophageal sphincter.Conclusions: There is considerable variation in the management of oesophageal coins in children, though two dominant strategies were identified. As endoscopy is significantly more invasive than observation, future research should aim to determine whether either is more effective and safer in children. There is a clear division in departmental adoption of HHMDs. However, in those sites using HHMDs there was little formal training in their use, and there are large variations in techniques and their role in clinical decision-making. [ABSTRACT FROM AUTHOR]

Background: Healthy eating guidelines for school‐aged children are available but without advice on portion sizes. This is a concern because consuming large portions is associated with an increased risk of overweight/obesity. The present study aimed to calculate recommended portion sizes for school‐aged children based on weight for age and use them to develop a meal plan to meet nutritional needs within energy requirements. Methods: Portion size data on foods consumed by school‐aged children (4–18 years) were extracted from two sources: (i) British National Diet and Nutrition Survey (1997) and (ii) Avon Longitudinal Study of Parents and Children (1997–2006). Foods were allocated to groups based on the UK Eatwell Guide and the US My Plate Model. Portion sizes were developed for a variety of foods. A meal plan that included portion size guidance and met healthy eating guidelines was developed based on the number of portions of each food group needed to meet dietary requirements. Results: Portion sizes were developed for 131 foods that were commonly eaten by children in age groups 4–6, 7–10, 11–14 and 15–18 years. The meal plan met requirements for energy and nutrients as specified by UK dietary reference values, except for vitamin D for which there are few dietary sources. Conclusions: Food portion sizes informed by usual intake in UK children can help inform dietary advice for a range of childhood settings and for parents. The meal plan included a wide variety of foods to encourage dietary diversity and meet energy and nutrient needs for school‐aged children. [ABSTRACT FROM AUTHOR]
