Background Panel data indicate that nonpregnant women's dietary diversity fluctuates across climatic seasons in low- and middle-income countries. The natural day-to-day variability in food group consumption during gestation is unknown. Objectives A longitudinal study was conducted among pregnant women enrolled in the Micronutriments pour la Sante de la Mere et de l'Enfant study 3 randomized controlled efficacy trial [i.e., daily fortified balanced energy-protein supplement and an iron-folic acid (IFA) tablet compared with an IFA tablet only] to investigate the number of 24-hour recalls required to estimate usual prenatal food group (FG) diversity and the seasonality of pregnant women's dietary diversity in Hounde, Burkina Faso. Methods FG consumption was assessed twice weekly by qualitative, list-based, 24-hour recalls among 1757 pregnant women (892 control, 865 intervention). The number of days needed to estimate a woman's usual prenatal 10-point FG diversity score was calculated using the within-subject coefficient of variation. Regression models, including truncated Fourier series, were fitted to assess seasonal variations in the FG diversity score and the probability of reaching Minimum Dietary Diversity for Women (MDD-W; i.e., >= 5 FGs). Results The monthly mean FG scores (

Background: Access to high-quality dietary intake data is central to many nutrition, epidemiology, economic, environmental, and policy applications. When data on individual nutrient intakes are available, they have not been consistently disaggregated by sex and age groups, and their parameters and full distributions are often not publicly available. Objectives: We sought to derive usual intake distributions for as many nutrients and population subgroups as possible, use these distributions to estimate nutrient intake inadequacy, compare these distributions and evaluate the implications of their shapes on the estimation of inadequacy, and make these distributions publicly available. Methods: We compiled dietary data sets from 31 geographically diverse countries, modeled usual intake distributions for 32 micronutrients and 21 macronutrients, and disaggregated these distributions by sex and age groups. We compared the variability and skewness of the distributions and evaluated their similarity across countries, sex, and age groups. We estimated intake inadequacy for 16 nutrients based on a harmonized set of nutrient requirements and bioavailability estimates. Last, we created an R package-nutriR-to make these distributions freely available for users to apply in their own analyses. Results: Usual intake distributions were rarely symmetric and differed widely in variability and skewness across nutrients and countries. Vitamin intake distributions were more variable and skewed and exhibited less similarity among countries than other nutrients. Inadequate intakes were high and geographically concentrated, as well as generally higher for females than males. We found that the shape of usual intake distributions strongly affects estimates of the prevalence of inadequate intakes. Conclusions: The shape of nutrient intake distributions differs based on nutrient and subgroup and strongly influences estimates of nutrient intake inadequacy. This research represents an important contribution to the availability and application of dietary intake data for diverse subpopulations around the world.

BACKGROUND Dietary supplements are commonly taken by adults in the United States and can contribute substantially to daily nutrient intakes. Short supplement-use questionnaires are often used in dietary surveys, but their accuracy has not been well studied. OBJECTIVES The primary objective was to evaluate the accuracy of a short, self-administered supplement frequency questionnaire (SFQ) relative to a comprehensive 1-y inventory of supplement use. A secondary objective was to compare SFQ responses for participants in the intensive measurement study to those from a control group to investigate a possible research participation effect. METHODS The Supplement Reporting study enrolled 1029 older adults in 2005-2006, with a mean age of 67.8 y, who participated in the Multiethnic Cohort and reported regular use of dietary supplements. Of these, 375 were interviewed quarterly to collect detailed information on types and amounts of dietary supplements used, while 654 served as the control group. All participants completed 2 SFQs, 1 y apart. RESULTS Agreement between the 2 instruments in use at least weekly ranged from 88% to 97% for 15 of 16 supplement types, with a lower agreement of 74% for vitamin D. The correlations of nutrient intakes from supplements between the 2 instruments were high, ranging from 0.48 to 0.75, except for iron (r = 0.29). However, mean nutrient intakes as reported on the SFQ were higher than intakes from the inventory for most nutrients, sometimes twice as high. Nutrient intakes based on the SFQ were similar for the inventory and control groups, at both baseline and the end of the study. CONCLUSIONS A self-administered short SFQ can be used in large surveys to identify participants who use 16 categories of dietary supplements at least once a week and can correctly rank participant intakes of nutrients. However, the SFQ does not accurately estimate absolute levels of nutrient intakes from supplements.

Background Information on long-term dietary intake is often required for research or program planning, but surveys routinely use short-term assessments such as 24-h recalls (24HRs). Methods to reduce the impact of within-person variation in 24HRs, such as the National Cancer Institute (NCI) method, typically require extensive training and skill. Objectives We introduce the Simulating Intake of Micronutrients for Policy Learning and Engagement (SIMPLE) macro, a new tool to increase the accessibility of 24HR analysis. We explain the underlying theory behind the tool and provide examples of potential applications. Methods The SIMPLE macro connects the core NCI statistical code to estimate usual intake distributions and includes additional code to enable advanced analyses such as predictive modeling. The related SIMPLE-Iron macro applies the full probability method to estimate inadequate iron intake, and the SIMPLE-1D macro is used for descriptive or modeling analyses of data with a single 24HR per person. The macros and associated documentations are freely available. We analyzed data from the US National Health and Nutrition Examination Survey (NHANES) and the Cameroon National Micronutrient Survey to compare the SIMPLE macro to 1) the core NCI code using the Estimated Average Requirement cut point method, and 2) the IMAPP software for iron only, and to demonstrate the applications of the SIMPLE macro for estimating usual intake and predictive modeling. Results The SIMPLE macro generates identical results to the core NCI code. The SIMPLE-Iron macro also produces estimates of inadequate iron intake comparable to the IMAPP software. The examples demonstrate application of the SIMPLE macro to 1) descriptive analyses of nutrient intake from food and supplements (NHANES), and 2) analyses accounting for breast-milk nutrient intake and modeling fortification and supplementation programs (Cameroon). Conclusions The SIMPLE macros may facilitate the analysis and modeling of dietary data to inform nutrition research, programs, and policy.

Background Women of childbearing age (WCBA) and women of menopausal age (WMENO) have distinct nutritional needs. Understanding nutrient intake and status in these life stages is critical for tailoring dietary recommendations. Objectives The objectives of this study were to evaluate total estimated usual nutrient intakes from food and food plus supplements and to compare these to established recommendations for WCBA and WMENO life stages and examine associations between self-reported estimated usual intakes and nutrient status biomarkers. Methods Twenty-four-hour dietary recall data from 2011–2016 NHANES were used to estimate usual intake of nutrients from food and food plus supplements for WCBA (aged 15–44 y, n = 4,134) and WMENO (aged 40–65 y, n = 3,438). Estimates of mean usual intake were derived and compared across clinically defined nutrient biomarker categories. Results Both young (aged 15–30 y) and older (aged 31–44 y) WCBA had intakes from food below the Estimated Average Requirement (EAR) for calcium (49% and 44%, respectively), magnesium (62%, 44%), and vitamins A (50%, 44%), C (47%, 46%), D (>97%, >97%), and E (92%, 88%). Similarly, perimenopausal (aged 40–50 y) and menopausal (aged 51–65 y) women had intakes from food below the EAR for calcium (48% and 74%, respectively), magnesium (50%, 49%), and vitamins A (44%, 37%), C (44%, 41%), D (>97%, >97%), and E (88%, 86%). Nutrient gaps decreased with supplement usage. For folate, vitamins D and B-12, and DHA, women in the lowest biomarker category (indicating increased risk of deficiency) had significantly lower intake from food (315.2 ± 25.9 compared with 463.8 ± 5.2 µg dietary folate equivalents, 3.5 ± 0.1 compared with 4.2 ± 0.1 µg, 3.6 ± 0.2 compared with 4.3 ± 0.1 µg, and 0.037 ± 0.005 compared with 0.070 ± 0.006 g, respectively; P

Planning nutritionally adequate intakes for large groups of people presents many challenges. Because of between-person variations in both food choices and nutrient requirements, it is necessary to examine nutrient intake distributions and select a Target Median Intake (TMI) that will lead to a low prevalence of inadequate nutrient intakes. The TMI may then be used to guide a feeding or education program. A comprehensive report from the Institute of Medicine evaluated nutrient intakes from the NHANES and recommended new meal patterns for all age groups (other than infants) served by the Child and Adult Day Care Food Program, which provides meals and snacks to children and adults in a variety of care settings. The Estimated Average Requirement, a DRI value, for each nutrient of interest was used to estimate both the prevalence of inadequate intakes as well as the changes in the intake distribution that are needed to reduce unacceptably high levels of inadequacy. For nutrients with an Adequate Intake (AI), the prevalence of inadequacy could not be estimated, but the AI could be used as the TMI. Simultaneously, it was important to ensure that the new intake distributions did not result in intakes that exceeded the Tolerable Upper Intake Level for any nutrient. Data for 2- to 4-y-old children are presented in detail to illustrate this process. Of 18 nutrients examined, analyses showed that intakes of vitamin E, potassium, and fiber should be increased, while intakes of sodium should be decreased. If more recent nutrient standards are used, revised assessments show that calcium intake should also be increased, while potassium intake is adequate. These methods and results should be useful when designing feeding programs for other population groups within the United States, as well as in other countries.

Dancers' energy demands fluctuate across the season. Accordingly, dancers should adapt their training and nutrition. Still, how to periodize nutrition in dancers remains unclear. This article aims to (1) introduce nutrition periodization and (2) provide recommendations for nutrition periodization in dancers. During preseason, dancers design, rehearse, and train. During in-season, dancers have one or more daily performances. During postseason, dancers rest and prepare for the next season. Nutrition periodization is the strategic and timed nutrient intake to meet varying seasonal energy demands. Overall, nutrition periodization can support dancers' training goals, enhance their performance, and support optimal recovery.

BACKGROUND In 2009 the USDA's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) updated the food packages provided to participants. OBJECTIVES This study investigates associations between WIC participation and nutrients and food groups consumed using data from the Feeding Infants and Toddlers Study's 2008 and 2016 nationwide, cross-sectional surveys of children

Food Frequency Questionnaires (FFQs) are valuable research tools in nutritional epidemiology. This study aimed to develop and validate a new semi-quantitative FFQ, specifically designed for the Italian population and best fitted for self-administration. During the development process, we adapted to Italian needs the validated FFQ proposed by the Fred Hutchinson Cancer Research Center, revising food items, food frequency scale, portion sizes, and time frame. To assess the validity of the proposed FFQ, we compared the estimated daily intake using FFQ with the mean of 3-day food diaries and one 24-hour recall (considered as reference method). The validation process was conducted among a cohort of 51 healthy subjects enrolled in a clinical trial. Four statistical tests were applied on 23 estimated nutrient intakes. Spearman's coefficients ranged from 0.223 (sodium) to 0.748 (alcohol) and were good (≥0.50) and acceptable (0.20-0.49) for 7 and 16 nutrients, respectively. Cross classification showed a good agreement (≥50% in the same tertile or ≤10% in the opposite tertile) for 7 nutrients. The weighted Cohen's kappa values indicated an acceptable outcome (0.20-0.60) for 13 nutrients. Bland Altman plots did not show heteroscedasticity in the error terms, despite the presence of a bias. Our study provided a new Italian semi-quantitative FFQ for self-administration with an acceptable validation level. Its definitive release requires additional refinements and efforts.

Literature reports suggest that subjective sleep quality is associated with nutrient intake in elderly people and workers. However, few studies have suggested an association between objective sleep quality and dietary intake in adolescents and young women. We hypothesized that objective sleep quality is associated with dietary intake in adolescents and young women. We evaluated the association between energy and nutrient intake and objective sleep quality in adolescents and young Japanese women. In a cross-sectional study of 80 women aged 18-27 years, dietary intake was assessed using the self-administered diet history questionnaire. Objective sleep quality was assessed by actigraphy. Lifestyle characteristics, dietary habits, and mental health were assessed using specific questionnaires. Subjects were classified into 3 groups according to sleep efficiency (SE80%, 80%-85%, and ≥85%), and the relationships between dietary intake and objective sleep quality were statistically evaluated. No significant differences occurred in lifestyle characteristics, physical activity levels, eating behavior, and mental health status among the 3 SE groups. Energy intake was significantly lower in the low-SE group than in the middle- (P = .004) and high- (P = .015) SE groups. Protein intake was significantly lower in the low-SE group than in the high-SE group (P = .034). The mean energy-adjusted intakes of vitamin K, vitamin B

Objective This study aimed to analyze the risk of nutritional intake and helminthiasis to experience underweight among elementary school students. Method This study applied case control design. This study was conducted in three sub-districts in Makassar City. There were 82 students from eight schools participated. Micronutrients and macronutrients intake were obtained by means of 2 × 24 h food recall questionnaire. Body Mass Index data was collected by weight and height measurement with the use of weight-scales and stature meter. Helminthiasis was diagnosed from faces laboratory analysis. Results There were no relationship among that variables. However, the intake of protein (p = 0.712; OR 1.28), vitamin B12 (p = 0.349; OR = 1.843) and Zinc (p = 0.675; OR = 1.417) give higher risk for the students to experience underweighted. Conclusion There was no significance relationship between macronutrient and micronutrient intake and helminthiasis with the underweighted incidence within the students in Makassar. However, inadequate intake of protein, vitamin B12, and zinc get higher risk to undergo underweight condition.

Two core nutrient intake reference values (NRVs) are required for assessing the adequacy and safety of nutrient intakes for population groups: the average requirement (AR) and the tolerable upper level of intake (UL). Applications of such assessments include providing advice to improve intakes, formulating complementary foods, estimating the amounts of nutrients to be added to fortified foods and monitoring changes in intake, and product labeling at the global, national, or regional level. However, there is a lack of unity across country-level organizations in the methodological approach used to derive NRVs, and ARs and ULs are lacking in many compilations, thus limiting the ability to assess nutrient intakes for their population groups. Because physiological requirements vary little across populations globally, and setting reference values requires determining an acceptable level of uncertainty, it is feasible to adapt current recommendations from different sources to harmonize these core reference values. The objective of this review is to demonstrate an approach for harmonizing the NRVs for ARs (here termed “H-ARs”) and ULs (“H-ULs”) that can be applied on a global scale to assessing intakes across populations. The approach incorporates the framework and terminology recommended by reports from the United Nations University, the National Academies of Sciences, Engineering, and Medicine (NASEM), the Institute of Medicine (IOM), and the European Food Safety Authority (EFSA). After reviewing available alternatives, the proposed harmonized values were selected from standards set by EFSA (for Europe) and the IOM (for the United States and Canada), giving priority to those published most recently. Justifications for the proposed values are presented, along with discussion of their limitations. Ideally, these methods should be further reviewed by an international group of experts. Meanwhile, the H-ARs and H-ULs suggested in this review can be used to assess intakes of populations for many applications in global and regional contexts.

BACKGROUND: Accurate and reliable methods to assess prevalence of use of and nutrient intakes from dietary supplements (DSs) are critical for research, clinical practice, and public health monitoring. NHANES has been the primary source of DS usage patterns using an in-home inventory with a frequency-based DS and Prescription Medicine Questionnaire (DSMQ), but little is known regarding DS information obtained from 24-h dietary recalls (24HRs). METHODS: The objectives of this analysis were to compare results from 4 different methods for measuring DS use constructed from two data collection instruments (i.e., DSMQ and 24HR) and to determine the most comprehensive method for measuring the prevalence of use and estimating nutrient intakes from DS for selected nutrients. NHANES 2011–2014 data from US adults (aged ≥19 y; n = 11,451) were used to examine the 4 combinations of methods constructed for measuring the prevalence of use of and amount of selected nutrients from DSs (i.e., riboflavin, vitamin D, folate, magnesium, calcium): 1) DSMQ, 2) 24HR day 1, 3) two 24HRs (i.e., mean), and 4) DSMQ or at least one 24HR. RESULTS: Half of US adults reported DS use on the DSMQ (52%) and on two 24HRs (mean of 49%), as compared with a lower prevalence of DS use when using a single 24HR (43%) and a higher (57%) prevalence when combining the DSMQ with at least one 24HR. Mean nutrient intake estimates were highest using 24HR day 1. Mean supplemental calcium from the DSMQ or at least one 24HR was 372 mg/d, but 464 mg/d on the 24HR only. For vitamin D, the estimated intakes per consumption day were higher on the DSMQ (46 μg) and the DSMQ or at least one 24HR (44 μg) than those on the 24HR day 1 (32 μg) or the mean 24HR (31 μg). Fewer products were also classed as a default or reasonable match on the DSMQ than on the 24HR. CONCLUSIONS: A higher prevalence of use of DSs is obtained using frequency-based methods, whereas higher amounts of nutrients are reported from a 24HR. The home inventory results in greater accuracy for products reported. Collectively, these findings suggest that combining the DSMQ with at least one 24HR (i.e., DSMQ or at least one 24HR) is the most comprehensive method for assessing the prevalence of and estimating usual intake from DSs in US adults. This trial was registered at clinicaltrials.gov as NCT03400436.

Background Individuals with irritable bowel syndrome (IBS) may modify their diet, which may pose nutritional risk. Further, some dietary approaches, such as a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs), are restrictive and may contribute to nutritional inadequacy. Objective Our aim was to evaluate habitual nutrient intake, diet quality, and diversity in IBS and the effect of a 4-week low FODMAP diet on these parameters compared with controls. Design Data from two randomized controlled trials were included for this secondary analysis. Participants were randomized to low FODMAP diet (n=63) or control diet (sham diet n=48, habitual diet n=19). Participants/setting Participants included 130 individuals with IBS referred to a tertiary center in London, UK between January 2010 to June 2011 and January 2013 to November 2014. Intervention Participants in one trial were randomized to receive either low FODMAP dietary counseling or sham control dietary counseling. In the other, they were randomized to receive low FODMAP dietary counseling or to continue habitual diet. All advice was provided by a specialist dietitian. Main outcome measures Habitual (usual) dietary intake at baseline (n=130) and after a 4-week intervention period was measured using 7-day food records. Statistical analyses performed Analysis of covariance and χ2 tests evaluated differences across groups at 4 weeks. Results When examining habitual intake of individuals with IBS, fiber intake was low, with only 6 (5%) achieving the target (30 g/day). In those receiving low FODMAP advice, there was no difference in intake of most nutrients compared with controls. However, there was lower intake of starch (109 g/day) vs habitual control diet (128 g/day; P=0.030), and higher intake of vitamin B-12 (6.1 μg/day) vs habitual (3.9 μg/day) and sham control diets (4.7 μg/day; P Conclusion This study demonstrates many individuals with IBS fail to meet dietary reference values for multiple nutrients. A 4-week low FODMAP diet, when delivered by a specialist dietitian, does not impact on intake of most nutrients or diet diversity but decreases diet quality compared with control diets.

Paraoxonase 1 (PON1) is considered to play a crucial role as an anti-atherosclerotic factor. The PON1 activity is affected by genetic polymorphisms, environmental factors, age, sex, lifestyle, pharmaceutical drugs, and dietary factors. The aim of this study was to evaluate the association between macro- and micronutrients as well as PON1 concentration and activities in patients with cardiovascular diseases (CVD), cardiovascular risk factors but no CVD (CRF), and in healthy controls (control group).A case-control study was carried out with 356 volunteers from the Mexican Institute of Social Security, Mexico. Clinical parameters, lipid profile, PON1 activities (AREase, LACase, CMPAase and PONase), and PON1 concentration were evaluated. There was a differential intake of macro- and micronutrients among the study groups. The intake of proteins and carbohydrates was higher in the CVD group than in the CFR and control groups (p 0.05). AREase, LACase, and CMPAase activities and PON1 concentration were lowest in the CVD group.LACase and CMPAase activities, as well as PON1 concentration, could be included in the battery of CVD predictive biomarkers in the Mexican population.

Feeding management of the postnatal and preweaning calf has an important impact on calf growth and development during this critical period and affects the health and well-being of the calves. After birth, an immediate and sufficient colostrum supply is a prerequisite for successful calf rearing. Colostrum provides high amounts of nutrient as well as non-nutrient factors that promote the immune system and intestinal maturation of the calf. The maturation and function of the neonatal intestine enable the calf to digest and absorb the nutrients provided by colostrum and milk. Therefore, colostrum intake supports the start of anabolic processes in several tissues, stimulating postnatal body growth and organ development. After the colostrum feeding period, an intensive milk feeding protocol, that is, at least 20% of BW milk intake/day, is required to realise the calf potential for growth and organ development during the preweaning period. Insufficient milk intake delays postnatal growth and may have detrimental effects on organ development, for example, the intestine and the mammary gland. The somatotropic axis as the main postnatal endocrine regulatory system for body growth is stimulated by the intake of high amounts of colostrum and milk and indicates the promotion of anabolic metabolism in calves. The development of the forestomach is an important issue during the preweaning period in calves, and forestomach maturation is best achieved by solid feed intake. Unfortunately, intensive milk-feeding programmes compromise solid feed intake during the first weeks of life. In the more natural situation for beef calves, when milk and solid feed intake occurs at the same time, calves benefit from the high milk intake as evidenced by enhanced body growth and organ maturation without impaired forestomach development during weaning. To realise an intensive milk-feeding programme, it is recommended that the weaning process should not start too early and that solid feed intake should be at a high extent despite intensive milk feeding. A feeding concept based on intensive milk feeding prevents hunger and abnormal behaviour of the calves and fits the principles of animal welfare during preweaning calf rearing. Studies on milk performance in dairy cows indicate that feeding management during early calf rearing influences lifetime performance. Therefore, an intensive milk-feeding programme affects immediate as well as long-term performance, probably by programming metabolic pathways during the preweaning period.

Consuming salad is one strategy with the potential to harmonize diets more closely with national dietary guidance. However, it is not known whether nutrient intake and diet quality differ between people who consume vegetable-based salad and those who do not.The objective of this study was to compare nutrient intake and diet quality between salad reporters and nonreporters.This study is a cross-sectional analysis of 1 day of dietary intake data collected via 24-hour recall.Adults 20 years and older (n=9,678) in What We Eat in America, National Health and Nutrition Examination Survey 2011-2014 were included. Respondents who ate salad on the intake day were considered salad reporters.This study estimated nutrient intake from all foods and beverages (excluding supplements) and evaluated diet quality using the Healthy Eating Index (HEI) 2015.Nutrient intake and HEI scores were compared between salad reporters and nonreporters using paired t tests with regression adjustment for confounding variables. Results were considered significant at P0.001.On the intake day, 23% of adults consumed salad. Energy, protein, and carbohydrate intakes did not differ between salad reporters and nonreporters. Salad reporters had higher intakes than nonreporters of dietary fiber, total fat, unsaturated fatty acids, vitamins A, B-6, C, E, K, folate, choline, magnesium, potassium, and sodium (P0.001). Total HEI 2015 scores were significantly higher for reporters (56 of a possible 100 points) than nonreporters (50 points) P0.001. Reporters also had significantly higher scores for eight of 13 HEI components: total vegetables, greens and beans, whole fruits, total protein foods, seafood and plant proteins, fatty acids, refined grains, and added sugars (P0.001).Incorporating vegetable-based salad into one's diet may be one effective way to increase nutrient intake and improve overall diet quality. Regardless of salad reporting status, HEI scores show that diets of US adults need improvement.

The aim of this study was to examine predictors of household food insecurity, dietary diversity, and children's mean micronutrient density adequacy and the relationship among these dietary measures.Baseline analysis of a quasi-experimental 16-mo intervention study conducted in 12 rural communities in the three main agroecological zones in Ghana. The study included 608 caregivers with their 2- to 5-y-old children. Nutrient density adequacy was estimated for a subsample of 120 children.Food insecurity was more severe among farming households than their non-farming counterparts (P = 0.032). Dietary diversity score was significantly higher among non-farming households than farming households (P0.001). Food insecurity was negatively correlated with both household dietary diversity (r = -0.385; P0.001) and child mean micronutrient adequacy (r = -0.305; P0.001). There was no significant correlation between dietary diversity and children's mean micronutrient density adequacy. Belonging to a household that is severely food insecure and household size were significant predictors of children's mean micronutrient density adequacy (ß = -0.124, P = 0.006; ß = 0.011, P = 0.006, respectively).Household food insecurity continues to be a good indicator of lower nutrient intake in children.

Twenty-eight bulls weighing 227 ± 6.8 (SD) kg were randomly assigned to four concentrate levels (1-1.5 kg [low level of concentrate {LC}], 1.5-2 kg [medium level of concentrate], 2-2.5 kg [high level of concentrate {HC}], and 2.5-3 kg [highest level of concentrate {H+C}]) and fed corn stover silage ad libitum. At the beginning of the experiment, the bulls in each treatment were fed 1, 1.5, 2, and 2.5 kg of concentrate, respectively, and these levels were increased by 0.25 kg at the end of each month to compensate for the growth requirements of the bulls. After three months, increases in the concentrate level from LC to HC resulted in increased (P

Rotatinuous stocking (RN) management is based on animal ingestive behaviour responses, where optimal pre- and post-grazing sward heights are defined to increase nutrient intake per unit of grazing time. We hypothesized that the optimal sward structure and consequently, a high herbage nutritive value in RN treatment results in a greater faecal nitrogen (N) excretion by sheep and consequently, a greater faecal greenhouse gas (GHG) emissions compared with the traditional rotational stocking (RT) management, which is based on a maximum herbage accumulation and harvest. Therefore, the aim of this study was to evaluate the effect of two grazing management strategies (RN and RT) on the amount of dry matter (DM) faecal excretion, faecal N excretion and faecal GHG (CH4 and N2O) emissions from growing sheep grazing Italian ryegrass pastures. In order to evaluate faecal production and N excretion per animal and per ha, a first experiment (1) was carried out: RT - pre and post-grazing sward heights of 25 and 5 cm, respectively and, RN - pre and post-grazing sward heights of 18 and 11 cm, respectively. A second experiment (2) was carried out to measure the CH4 and N2O fluxes from faeces, using the static chamber method. Daily DM faecal and N excretion per animal were higher (P < 0.001) in RN compared with RT treatment. However, when considered daily DM faecal and N excretion per ha, results were lower (P < 0.001) for the RN than the RT treatment. CH4 and N2O emissions from faeces were higher (P < 0.001) in RN compared with RT treatment, both per animal and per hectare. In conclusion, our study showed that the RN grazing management, based on animal behaviour, resulted in a higher daily N excretion per animal and higher CH4 and N2O emissions from faeces of sheep grazing Italian ryegrass pastures. This study contributes to improve GHG national inventories for the subtropical Brazilian climatic conditions, where estimations from CH4 and N2O emissions factors for faeces from growing sheep grazing Italian ryegrass are markedly lower than the values reported by IPCC Default Tier 1.

The majority of lamb mortality which occurs during the first 24 h post-partum is preventable through providing the lamb with sufficient quantities of high quality colostrum during this time. Data from seven late gestation nutrition experiments carried out at this institute between 2002 and 2014 were collated into a single data set comprising of 415 twin bearing ewes. Analysis was carried out to investigate the key drivers of ewe colostrum production excluding nutrient intake, namely body reserve mobilisation, ewe breed type, ewe age, gestation length and lamb birth weight. The volume of colostrum produced at 1 and 18 h post-partum was significantly lower than the volume recorded at 10 h post-partum (P = 0.01). Multivariate regression analysis indicated that colostrum volume during the first 18 h post-partum was influenced by lamb birth weight (P = 0.01), ewe age (P = 0.01), breed type (P = 0. 01) and gestation length (P = 0.06). Live weight change (P = 0.05) also had a significant influence on the volume of colostrum produced but BCS change did not affect colostrum production (P = 0.25). Further multivariate regression analysis indicated that IgG yield was influenced ewe breed type (P = 0.01), lamb birth weight (P = 0.02), gestation length (P = 0.05) and BCS change (P = 0.04). Live weight change (P = 0.12) and ewe age (P = 0.62) did not influence the quantity of IgG produced. Leicester ewes produced less colostrum per kg lamb birth weight at 1 h post-partum compared to all other ewe breed types (P = 0.01) and less than Suffolk ewes at 10 h post-partum (P = 0.01). The result of this analysis shows the key factors excluding ewe nutrition that drive colostrum production. Ewe breed type in particular appears to play an important role in the ability of the ewe to produce sufficient quantities of adequate quality colostrum. In conclusion the result of this analysis highlights the important factors associated with ewe colostrum volume and IgG yield excluding nutrition. In particular the overall structure of the flock such as breed type and ewe age is important when considering the ability of the flock to meet colostrum demands and hence reduce lamb mortality.

Background Many updates to young child feeding recommendations have been published over the past decade, but concurrent intake trends have not been assessed. Objective The aim of this study was to evaluate adequacy and trends in energy and nutrient intakes of US infants and children aged 0–47.9 mo through use of Feeding Infants and Toddlers Study (FITS) data from 2002, 2008, and 2016. Methods FITS are cross-sectional surveys of parents/caregivers of infants and young children (FITS 2002, n = 2962; FITS 2008, n = 3276; FITS 2016, n = 3235). Dietary intakes were assessed by telephone with trained interviewers using the Nutrition Data System for Research. Mean ± SE nutrient intakes were calculated. Diet adequacy was assessed with the nutrient adequacy ratio (NAR) for 17 nutrients and the corresponding mean adequacy ratio. Results Energy and macronutrient intakes were generally stable across surveys, but significant decreases for saturated fat and total sugars and an increase in fiber were observed among 6–11.9-mo-olds and 12–23.9-mo-olds (P-trend < 0.0001). Mean sodium intakes exceeded Adequate Intakes (AI) for all ages, whereas fiber intakes were universally below the AI. Nutrients with the lowest NAR values were vitamin D (range 0.41–0.67/1.00) and vitamin E (range 0.60–0.79/1.00 for 2008 and 2016). For iron, infants aged 6–11.9 mo had the lowest NAR values at 0.77–0.88/1.00, compared to 0.85–0.89/1.00 for 12–47.9-mo-olds. Potassium was low from 12 to 47.9 mo (NAR range 0.55–0.63/1.00 across survey years). The nutrients with the greatest decline in mean intakes were iron and vitamins D and E among 6–11.9-mo-olds, and vitamin D and potassium among 12–23.9-mo-olds in 2016 compared to 2002. Conclusions The diets of US infants and young children were generally adequate for most micronutrients and stable over time, but sodium intakes were too high, and nutrient gaps still existed, especially for vitamins D, E, and fiber across ages and for iron among infants.

Background Assessing nutritional intake in all-you-care-to-eat dining facilities poses unique challenges. New methods that streamline accurate data collection would facilitate better nutrition intervention research in this dining hall environment, which is common on university campuses. Objective To compare nutrient and food group intake data of university undergraduate students from a single visit to an all-you-care-to-eat campus dining hall, collected by two methods: multiple-pass dietary recall interview and self-administered, electronic survey. Participants/setting Undergraduate students (n=42) ages 18 and older were recruited as they exited the dining hall during lunch service hours during 1 week. Design Using a cross-sectional design, participants completed two dietary assessment methods in random order: an electronic tablet-based exit survey listing the available menu items at that service with drop-down menus to report portion size consumed and a multiple-pass structured dietary interview by a single, trained interviewer. Statistical analyses performed Agreement of nutrients and food groups between the two methods was assessed by Pearson and Spearman correlations and paired t tests. Significance was set at P Results Respondents were primarily underclassmen and women who lived on campus, with 16 of 42 students identifying as white. Students reported an average of 1.1 additional food items via the diet interview method compared with the survey. Average kilocalorie intake by the interview and survey methods was 837±561 and 860±586, respectively. Mean intake of all measured nutrients and all food groups except total and lean protein was not significantly different across the two methods. Spearman correlations between method results ranged across nutrients from r=0.541 to r=0.998 and across food groups from r=0.507 to r=0.948; all were significant at P Conclusions The electronic survey method performs similar to a multiple-pass dietary interview in assessing mean nutrient intake of ethnically diverse university undergraduates in a single eating occasion at an all-you-care-to-eat dining hall, but the survey may not be as efficient at capturing the total number of food items consumed.

OBJECTIVES: Christian Orthodox fasting (COF), a periodical vegetarian subset of the Mediterranean diet, has been proven to exert beneficial effects on human health. Athonian fasting is a pescetarian COF variation, where red meat is strictly restricted throughout the year. Previous studies have examined the COF nutritional synthesis and health effects in general population fasters (GF) and Athonian monks (AM), separately. The aim of this study is to comparatively evaluate the characteristics and effects of this nutritional advocacy between the two populations. METHODS: The study included 43 male GFs (20-45 y of age) and 57 age-matched male AMs following COF. Dietary intake data were collected in both groups during a restrictive (RD) and a nonrestrictive (NRD) day. Nutritional, cardiometabolic, and anthropometric parameters were compared between the two cohorts. RESULTS: AM presented lower daily total caloric intake for both RD (1362.42 ± 84.52 versus 1575.47 ± 285.96 kcal, P < 0.001) and NRD (1571.55 ± 81.07 versus 2137.80 ± 470.84 kcal, P < 0.001) than GF.They also demonstrated lower body mass index (23.77 ± 3.91 versus 28.92 ± 4.50 kg/m2, P

The literature on the role of inflammation in health has grown exponentially over the past several decades. Paralleling this growth has been an equally intense focus on the role of diet in modulating inflammation, with a doubling in the size of the literature approximately every 4 y. The Dietary Inflammatory Index (DII) was developed to provide a quantitative means for assessing the role of diet in relation to health outcomes ranging from blood concentrations of inflammatory cytokines to chronic diseases. Based on literature from a variety of different study designs ranging from cell culture to observational and experimental studies in humans, the DII was designed to be universally applicable across all human studies with adequate dietary assessment. Over the past 4 y, the DII has been used in >200 studies and forms the basis for 12 meta-analyses. In the process of conducting this work, lessons were learned with regard to methodologic issues related to total energy and nutrient intake and energy and nutrient densities. Accordingly, refinements to the original algorithm have been made. In this article we discuss these improvements and observations that we made with regard to misuse and misinterpretation of the DII and provide suggestions for future developments.

Objectives To our knowledge, the overall nutritional quality of the Japanese diet has not been assessed previously. The aim of this study was to investigate the relationship between adhering to a Japanese diet and nutrient intake. Methods We conducted a cross-sectional study of 1129 Japanese persons ≥70 y of age. Dietary habits were assessed using a food frequency questionnaire. The primary outcome was nutrient intake (12 components of NRF9.3 index). The overall nutrient adequacy (ONA) score was applied for assessing the potential of nutrient density. Correlation analysis was performed to compare the Japanese Diet Index (JDI) and nutrient intake, and multiple regression analysis was used to simulate the modified JDI (MJDI). Results The JDI was positively correlated with all nine beneficial nutrients, and negatively correlated with two nutrients (saturated fat and sugar). The JDI was significantly correlated with the ONA score (Spearman's coefficient = 0.248). The MJDI, which was defined by the coefficients for seven food items, was significantly correlated with the ONA score (Spearman's coefficient = 0.515). However, the JDI and MJDI were correlated with higher sodium intake. Conclusions The present findings suggest that adhering to a Japanese diet defined by the JDI score is associated with better nutrient intake. However, this dietary pattern also appears to be associated with high sodium intake.

The digestion of ruminal fibrous substrate is slow or incomplete and can hinder animal performance. Hence, the current study investigated the effect of oat-silage-to-concentrate ratios supplemented with exogenous fibrolytic enzymes (EFE) on production performance and nutrient digestibility in 32 Nilli Ravi early lactating buffaloes. Four diets were formulated and grossly divided across two major experimnatl groups of two proportions of silage to concentrate ratios (AS-60, silage to concentrate ratio of 60:40; and AS-70, silage to concentrate ratio of 70:30) with or without EFE supplementation. Crude protein, and neutral detergent fiber intake as well as digestible nutrient intake were significantly (P

When conducting research on polyphenols and their effects on health, it is of primary importance to use standardised and validated dietary assessment tools. This paper aims at assessing the validity of a food frequency questionnaire (FFQ) for quantifying dietary polyphenol exposure among healthy adults using the method of triads. Fifty-three healthy adults, aged 20-60, were included in the study. Total dietary polyphenol intake (TDP) estimated by the FFQ was compared with TDP measured by a 3-day food record (FR) and with urinary excretion levels of total polyphenols (TUP). Pearson correlations were calculated between methods. Validity coefficients (VC) were estimated between the three measurements and the 'unknown' true intake. There was a strong correlation between both dietary methods (r = 0.70, p 0.0001). A moderate but significant association was observed between FFQ-derived TDP and TUP (r = 0.32, p = 0.020). The method of triads yielded a VC for the FFQ of 0.63 (95%CI: 0.41-0.84), indicating a strong relationship between FFQ-derived TDP and the true polyphenol intake. This study shows that the FFQ is an adequate tool not only for measuring dietary polyphenol exposure in nutrition epidemiological studies but also for guiding clinicians in dietary advice and counselling.

Refereed/Peer-reviewed Background: Food selectivity is an emerging health concern among children with autism spectrum disorder (ASD). Food selectivity is used to describe food refusal, limited food choices, and/or food fussiness. Method: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-Scoping Review Guidelines to systematically identify the relationship between food selectivity and oral sensory sensitivity and the possible consequences of food selectivity on nutrient intake in children with ASD.Thirty studies were included in the review based on search terms from three online databases. Results: Assessment of food selectivity, oral sensory sensitivity, and nutrient intake was found to be focused primarily on the parent-report technique. Only a handful of studies have used Cronbach’s alpha to measure the psychometric properties. Twenty-one of the included studies reported a higher rate of food selectivity in children with ASD than typically developing (TD) children. Notably, several studies (n =7) have identified oral hypersensitivity (e.g., taste/smell) as a significant risk factor for food aversion and/or limited variety in children with ASD. Compared with TD children, the ASD group significantly consumed significantly fewer fruits/vegetables (n = 8). The intake of micronutrients, including vitamin A, vitamin B6, folate, vitamin B12, vitamin C, vitamin D, calcium, iron, and zinc that associates with food selectivity, was also low (n=13). Conclusion: Implementation of screening and assessment protocols using valid and reliable instruments to identify food selectivity and oral sensory sensitivity is crucial for the medical evaluations of children with ASD.

Objective This review summarizes the current and previous data on dietary supplement (DS) use collected from participants in the National Health and Nutrition Examination Survey (NHANES), describes the NHANES dietary supplement database used to compute nutrient intakes from DSs, discussed recent developments and future direction, and describes many examples to demonstrate the utility of these data in informing nutrition research and policy. Background and history Since 1971, NHANES, has been collecting information on the use of DSs from participants. These data are critical to national nutrition surveillance and have been used to characterize usage patterns, examine trends over time, assess the percentage of the population meeting or exceeding nutrient recommendations, and to help elucidate the sources contributing nutrients to the diet of the US population. Rationale Over half of adults and about one-third of children in the United States use at least one dietary supplement in the past 30 days. Dietary supplements contribute to the dietary intake of nutrients and bioactive compounds in the US and therefore need to be assessed when monitoring nutritional status of the population and when studying diet-health associations. Recent developments With the recent development and availability of the Dietary Supplement Label Database (DSLD), a comprehensive DS database that will eventually contain labels for all products marketed in the US, NHANES DS data will be more easily linked to product information to estimate nutrient intake from DS. Future directions Over time, NHANES has both expanded and improved collection methods. The continued understanding of sources of error in collection methods will continue to be explored and is critical to improved accuracy. Conclusions NHANES provides a rich source of nationally representative data on the usage of dietary supplements in the US.

This study was conducted to test the hypothesis that palm kernel cake could be included in diets for goat kids without reducing their growth rate and carcass traits. Forty non-castrated crossbred Boer × indigenous goat kids were supplemented with palm kernel cake at levels of 0, 7, 14 and 21% of the total dry matter (DM) in their diet. Palm kernel cake inclusion in the goat kid diet increased the ether extract (EE; P

Food neophobia is a widely prevalent eating behavior among children, which has been linked to poor dietary variety and quality. Nevertheless, data pertaining nutrient intakes in relation to food neophobia among children in Middle East countries are lacking. The present study aimed to examine the associations between food neophobia and nutrient intakes in children aged 6–12 years. A cross-sectional study of 424 children was conducted. Food neophobia among children was evaluated using the Food Neophobia Scale. Dietary data of children were collected using 24-hour dietary recalls, and nutrient densities were calculated. Intakes of macro- and micronutrients were compared to dietary recommendations. Proportions of children who met the dietary recommendations for all nutrients were similar across food neophobia groups. No significant difference in macro- or micronutrient intake was observed across categories of food neophobia in univariate analyses; however, in multiple regression models, higher food neophobia score was associated with lower protein intake (β = -0.04% of total energy, 95% CI −0.07 to −0.01), cholesterol (β = -1.79 mg/1000 kcals, 95% CI −3.51 to −0.06), potassium (β = -11.02 mg/1000 kcals, 95% CI −20.5 to −1.54), phosphorus (β = -5.30 mg/1000 kcals, 95% CI −9.74 to −0.86), magnesium (β = -1.20 mg/1000 kcals, 95% CI −2.15 to −0.25), iron (β = -0.07 mg/1000 kcals, 95% CI −0.14 to −0.01), zinc (β = -0.04 mg/1000 kcals, 95% CI −0.07 to −0.001), and selenium intake (β = -0.48 ug/1000 kcals, 95% CI −0.93 to −0.04). Our findings suggest negative associations between food neophobia in children and intake of a number of important nutrients. Further investigations are needed to identify potential factors that could influence food and nutrient intake among food neophobic children.

Background Research evidence suggests that the prevalence rate of Autism Spectrum Disorder (ASD) is increasing in India. In addition to socio-behavioral problems, diet-related issues are common and recurrent problems experienced by children with ASD. As there is only minimal research work done on these aspects, the present study is carried out as a case control snapshot to investigate the nutrient intakes of ASD children (n = 104) residing in the Mysore region, India. This data is compared with the nutrient intakes of Typically Developing (TD) controls (n = 121). Methods We evaluated ASD severity using Indian Scale for assessment of autism (ISAA). All the children aged (2–15 years) were examined for anthropometric measurements and hemoglobin levels. Dietary intakes and mealtime behavior problems were assessed using three-day food records and food frequency questionnaires. Results Significantly (p Conclusion Observations strongly indicate that well-timed nutritional screening and personalized dietary interventions can prevent/manage the nutritional deficiencies prevalent among ASD children of this region.

Twenty-eight male, weaned Chinese Holstein calves ((156.8±33.4) kg) were used to investigate the effects of dietary forage to concentrate ratio (F:C) and forage length on nutrient digestibility, plasma metabolites, ruminal fermentation, and fecal microflora. Animals were randomly allocated to four treatments in a 2×2 factorial arrangement: whole-length forage (WL) with low F:C (50:50); WL with high F:C (65:35); short-length forage (SL) with high F:C (65:35); and SL with low F:C (50:50). Chinese wildrye was used as the only forage source in this trial. The grass in the SL treatments was chopped using a chaff cutter to achieve small particle size (∼50% particles >19 mm). Dry matter intake (DMI) and organic matter (OM) intake was increased by increasing both F:C (P0.05). Microflora similarity was 50–73% among the different treatments. It is concluded that the WL with high F:C (65:35) diet is suitable for weaned calves.

For nearly 20years, the National Food and Nutrient Analysis Program (NFNAP) has expanded and improved the quantity and quality of data in US Department of Agriculture's (USDA) food composition databases (FCDB) through the collection and analysis of nationally representative food samples. NFNAP employs statistically valid sampling plans, the Key Foods approach to identify and prioritize foods and nutrients, comprehensive quality control protocols, and analytical oversight to generate new and updated analytical data for food components. NFNAP has allowed the Nutrient Data Laboratory to keep up with the dynamic US food supply and emerging scientific research. Recently generated results for nationally representative food samples show marked changes compared to previous database values for selected nutrients. Monitoring changes in the composition of foods is critical in keeping FCDB up-to-date, so that they remain a vital tool in assessing the nutrient intake of national populations, as well as for providing dietary advice.

International audience; Feed is the largest cost in animal production, therefore improving feed efficiency (FE) is one of the main priorities when redesigning farming systems. The objective of this work was to evaluate the effects of a divergent genetic selection for FE in Romane rams [i.e. efficient (RFI-) or inefficient (RFI+)] on the feed intake and nutrient digestibility of their daughters (ewes), reared in different conditions. Different to their sires, which were fed high concentrate-diets, the ewes were fed ad libitum total mixed ration (TMR) composed of silage (65%), hay (25%) and barley (10%). A series of in vivo digestibility trials were conducted using Romane ewes (n =20; 10 RFI- and 10 RFI+) during their 2 first production cycles. The BW, metabolic BW (MBW), body condition score (BCS), DM intake (DMI) and nutrient intake and digestibility were individually monitored. All parameters were significantly affected (P < 0.05) by the production cycle. The BW, MBW, BCS as well as the feed intake and nutrient digestibility were higher in the cycle 2 compared to cycle 1. The exception was the CP digestibility, which was higher in younger ewes (cycle 1). The BW and MBW was, as expected, higher in older ewes thus increasing the feed intake capacity in cycle 2 compared with cycle 1. Slight differences in TMR nutritive composition between the years of the study were also probably responsible of differences in CP digestibility. The RFI+ ewes showed a better BCS than RFI- ewes (3.0 vs. 2.7; P < 0.0001). In the conditions used in this study, we could not demonstrate any differences in intake and digestive efficiency between the two ewe FE lines, probably because the selected rams were tested with one diet (concentrate-based diet) whereas their daughters (ewes) with another (forage-based diet). Further research is warranted to evaluate RFI testing in animals fed a more fibrous diet closer to that of ewes under range conditions whereas also assessing responses to multiple-generation divergent selection on RFI.

This study aimed to evaluate the effect of feeding growing Awassi lambs on sweet lupin (LUP; Lupinus angustifolius) on nutrient intake, in vivo digestibility, growth performance and carcass quality. Twenty-seven lambs (average body weight (BW) 16.5 ± 0.88 kg) were assigned randomly to 3-diet groups, namely:1) no LUP (CON), 2) 125 g/kg LUP (LUP125) or 250 g/kg (LUP250) dry matter (DM) in replacement of portion of barley grain and soybean meal. The study lasted for 84 days (first 7 days were used as adaptation period followed by 77 days to collect the data). Nutrient intake was measured daily. Lambs’ BW was measured at the commencement of the study and every two weeks during the whole study. On day 60, 15 lambs (5 from each group) were chosen at random and moved to metabolism cages to determine nutrient in vivo digestibility and N balance parameters. Lambs fed LUP250 showed greater (P ≤ 0.05) intakes of DM, crude protein and ether extract than the CON and LUP125 fed groups; however, their NDF data tended (P = 0.07) to surpass other groups. Intake of metabolizable energy was greater (P = 0.02) in lupin-containing diets than the CON diet. Lambs’ fed LUP250 diet had greater (P

Many researchers use data from Household Consumption and Expenditure Surveys (HCES) to estimate individual food and nutrient intake when individual dietary data are not available. They assume that food is allocated within households according to members’ proportional energy requirements relative to an adult male (called an adult male equivalent, or AME). This study sought to validate AME-based estimates of individual consumption of calories, protein, iron, and animal source protein (ASP) across 10 age-sex categories, using data from Bangladesh and Ethiopia containing both household and individual-level consumption data. The study also assessed the accuracy of adjusting for meal partakers and physical activity levels (PAL), and compared energy-weighted AMEs to nutrient-specific AME predictions. Energy AME-based predictions of nutrient intake were generally accurate within ten percentage points of individually reported intakes, but were less accurate for infants 6–23 months and children in Bangladesh than for other demographic groups. AME predictions were more accurate: (1) in Ethiopia than in Bangladesh, (2) for predicting intake of the three nutrients rather than ASP, (3) for estimating nutrient intake rather than adequacy, (4) using energy-weighted AMEs rather than nutrient specific weights, and (5) using moderate PAL for youth and adults rather than high PAL. Adjusting for meal partakers did not consistently improve the AME-based predictions. Energy based AME estimates from household data can produce a useful proxy of average intake for certain population subgroups, however individually measured dietary assessment remains the best approach to identify groups at risk of nutrient inadequacy.

Our purpose in this paper is to present a proper diet model for diabetics in the fuzzy environment. In previous studies many efforts were made regarding preparation of a diet model appropriate for different age groups .but in most studies the daily nutrient intake decisions were made based on crisp data. By prescribing a diet based on crisp data, some of realities are neglected. For the same reason, we dealt with human diet problem through fuzzy approach. Also due to the importance of nutrition for individuals, especially patients with diabetic diseases, we have provided nutrition model as multi-objective fuzzy linear programming problem in which minimization of saturated fats, Sugar, and maximization of carbohydrate and total fiber are considered as our objectives. Results indicated uncertainty about amount of nutrients and their intake affects diet quality making it more realistic.

Highlights • Dietary energy assessment does not require matching foods in cooked form. • Macronutrient dietary assessment does not require matching foods in cooked form. • Vitamin and mineral dietary assessment requires matching foods in cooked form., In many countries, statistics from household consumption and expenditure surveys are increasingly being used to inform policies and programs. In household surveys, foods are typically reported as they are acquired (the majority are raw). However, the micronutrient content of some foods diminishes during processing and cooking. Using food consumption data from the 2015/16 Kenya Integrated Household Budget Survey, this study analyzes whether mean consumption estimates of dietary energy, macronutrients, and eight micronutrients are equivalent (applying a two-side paired equivalence test) when matching foods: (1) considering the nutrient content in raw foods (as reported in the survey), and (2) considering the nutrient content in foods as typically consumed, thus applying yield and retention factors as needed. Both food matching approaches rendered statistically equivalent mean consumption estimates, at national and county levels, for dietary energy, protein, fats, available carbohydrates, total fiber, calcium and zinc. Non-equivalent means were found for iron, vitamins A, B1, B2, B12, and C. The higher differences between the means were, in percentage change, for vitamin C (47 %), B1 (34 %) and B12 (26 %).

Food oral processing research has attracted a great deal of attention in the last few decades owing to its paramount importance in governing sensory appreciation and pleasurable experience of consuming foods and beverages and eventually regulating nutrient intake. A range of physiologically-controlled unit operations from first bite, to particle size reduction, mastication with saliva, bolus formation, swallowing to generation of oral residues occur during oral processing of solid foods across a range of time and length scales resulting in various physical, biochemical and psychological consequences. Tribology is the study of friction and lubrication, and it has emerged as a key tool to deconvolute these complex processes and provide insights into the physics of oral processing and sensory perception. This review provides an overview of “oral” tribology including experiments in the last decade on food colloids and lubrication theories, and highlights a perspective on how the field is evolving to address various food science challenges. This includes current and forecast future applications of tribology in designing healthier foods, creating sustainable alternatives without compromising mouthfeel, tackling food counterfeiting and tailoring foods for aging populations. We also examine a suite of advanced complementary techniques such as imaging, scattering, and adsorption using specific examples from allied fields that would be useful to uncover frictional dissipation in food systems in the future. The perspectives provided in this review thus represent an exciting glimpse of what tribology can offer, which may become a routine and integral step in food colloidal design in the future.

Background: Among Liver Transplantation (LT) recipients malnutrition is ubiquitous due to various metabolic aberrations and poor nutrient intake. It is imperative to recognize the diverse aspects which can alter patients’ food and nutrient intake. Aim The study aimed to provide the much-needed data on various conducive and deterrent factors for calorie and protein intake of the pre-LT patients. Methods In the present exploratory study 54 adult pre-LT patients were purposively selected. Information regarding patient's personal, medical history, nutrient, and dietary intake through 24- Hour Dietary recall and other factors like appetite (SNAQ), number of meals, duration of present illness, excessive fatigue, ascites, sound sleep, functional status, advice to increase intake, supplement recommended were gathered by patients’ interviews and OPD visits. Results The data showed significantly lower-calorie, protein, and calcium intake among pre-LT recipients as per the recommendations (p Conclusions Higher appetite, sound sleep, and higher numbers of meals consumed were conducive factors for calorie and protein intake among patients in the pre-transplant phase while no dietary advice for improving food intake was shown to be a deterrent factor. While planning diet, considerations and appropriate alterations of these factors can positively regulate the nutrient intake and nutritional status of the pre-LT patients.

OBJECTIVES: Adopting environmentally sustainable diets can substantially reduce anthropogenic greenhouse gas emissions (GHG). However, there remain concerns that consuming sustainable foods will increase the likelihood of nutritional deficiencies in periods of increased demand, including pregnancy. This study aimed to identify commonly consumed foods of pregnant women and determine the effect of their replacement with sustainable alternatives on nutrient intake and measures of environmental sustainability. METHODS: Dietary intake data from 171 pregnant women were assessed using a validated food frequency questionnaire. The food groups and food items that contributed most to energy and protein intake were identified. Of these foods, those that produce the highest GHG emissions (Poore et al. 2018) were matched with proposed sustainable alternatives for energy and protein content, and their impact on nutrient provision and sustainability measures were determined. RESULTS: Meats (bovine, poultry, fish, lamb and eggs), grains and dairy products were important sources of both energy and protein intake. With the highest GHG emissions, beef was selected as the reference food. Proposed food alternatives included lamb, chicken, eggs, fish, tofu, legumes and nuts. The most pronounced reductions in CO(2) emission were from replacing beef with tofu, legumes and nuts. For example, replacing one serve of beef with an isocaloric serve of firm tofu per week during pregnancy could reduce GHG emissions by 372 kg CO(2) eq, equivalent to that produced by an average passenger vehicle driving 1498 km. This replacement would not adversely impact iron (+1.1mg per serve) content, whilst providing a richer source of calcium (+294.8mg per serve), folate (+28.1µg per serve) and dietary fibre (+3.3g per serve). A once-weekly substitution of animal-derived foods for more sustainable plant-based alternatives within the context of a mixed diet has minimal effect on overall nutrient intake. CONCLUSIONS: Simple dietary substitutions, as little as replacing one serve of red meat with sustainable alternatives weekly, can substantially reduce environmental impact without compromising nutrient adequacy. These sustainable food replacements should be the focus of future applied clinical research. FUNDING SOURCES: No funding support for conducting this project was received.

OBJECTIVES: Characterize relationships between dietary patterns and the cardiometabolic profile of Peruvian children at risk of undernutrition. METHODS: The study was nested in the Peru site of the ‘MAL-ED’ study, a longitudinal birth cohort to evaluate relationships between diet, enteric exposures and child growth and development. Dietary recalls were collected from 9–24 months of age. At 3–5 years, we conducted a follow-up. Three additional dietary recalls were collected, and blood pressure, height, weight, subscapular skinfolds, and fasting plasma glucose, insulin, and lipid profiles were assessed. Nutrient intakes were expressed as average density per 100 kcals i) from 9–24 months, and ii) at follow-up. Reduced rank regression (RRR) was used to identify the combination of nutrient intakes explaining the greatest variation in the outcome variables. Multiple linear regression models adjusting for subscapular skinfold-for-age Z-scores (SSFZ) were used to test whether observed relationships were mediated by body composition. RESULTS: Of the 153 children included, 26% were stunted at follow-up. RRR extracted 2 factors explaining 7% of the variation in infant nutrient intakes and 12% of the variation in response variables. The first factor had higher loadings for vitamin D, calcium, and cholesterol, while the second had higher loadings for non-animal source protein and iron. RRR also extracted 2 factors from the child intake data. These factors had higher loadings for sugar and fats, and sugar and protein, respectively. The first infant RRR factor was associated with lower plasma triglycerides and higher high-density lipoprotein, whereas the second was associated with higher homeostatic model assessment-insulin resistance (HOMA-IR) and weight-for-height Z-scores (WHZ). The first child RRR factor was associated with higher triglycerides, HOMA-IR, and WHZ, and the second was related to higher blood pressure. Associations with glucose and insulin, but not blood pressure or cholesterol, were attenuated after adjusting for SSFZ. CONCLUSIONS: Nutrient densities of the diet in each childhood are associated with cardiometabolic profile in a chronically undernourished population. FUNDING SOURCES: The project was supported by the Thrasher Foundation and the BMGF.

OBJECTIVES: To characterize nutrient intakes and identify key food sources among Bhutanese refugee adults eligible for SNAP (Supplemental Nutrition Assistance Program) benefits. METHODS: We recruited a convenience sample of Bhutanese refugee adults (n = 54, mean age = 47 y, 83% female) residing in New Hampshire. Diet was estimated from foods recorded using three 24-hr recalls. Selected nutrients included vitamins C, D, E, and K, thiamin, riboflavin, niacin, B6, folate, B12, pantothenic acid, calcium, magnesium, sodium, and saturated fat. Participants were categorized based on meeting the Recommended Dietary Allowance (RDA) or Adequate Intake (AI) of selected nutrients. For sodium and saturated fat, meeting recommendations was defined as consuming

OBJECTIVES: Ready-to-eat cereal (RTEC) has been associated with improved intake of under-consumed nutrients. This study was conducted to examine consumption of RTEC and its association with nutrient intake and nutrition adequacy in the United States using the most recent nationally representative data. METHODS: Data from National Health and Nutrition Examination Survey (NHANES) 2017–2018 was used. Participants were classified as RTEC eaters or non-eaters depending on whether RETC was reported in their day-1 dietary recall. Total daily nutrient intake was compared by RTEC consumption status using ANOVA for survey data. Percentages below Estimated Average Requirement (EAR) for selected vitamins and minerals that are usually fortified in RTEC products were calculated using the National Cancer Institute method as estimate of usual intake. Data were analyzed in children (2–17 y, N = 2135), adults 18–64 y (N = 3675), and older adults (65 y or older, N = 1221) separately. RESULTS: Among children, 34% reported RTEC consumption. The percentage of RTEC consumers was 14% in adults 18–64y and 22% in adults 65y or older. Consumption of RTEC was associated with significantly higher intake of carbohydrate, dietary fiber, calcium, iron, zinc, magnesium, potassium, phosphorus, vitamin A, thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, and vitamin D (all P

OBJECTIVES: An estimated 50 million adults in the US have chronic pain, and is one of the most cited reasons for seeking medical treatment. There are well-established associations between dietary patterns, nutrient intake, and musculoskeletal health. Dietary habits can influence inflammation and inflammatory markers, both of which can contribute to chronic pain, however few studies have examined the association between dietary intake patterns and chronic pain. The present study examines the relationship between chronic pain and dietary behaviors in a nationally representative sample of US adults. METHODS: Pain assessment was conducted during only one cycle of NHANES (2009–2010). During the examination visit, participants between 20–69 years were asked questions related to pain location and duration. Individuals with chronic pain were identified as those who reported current pain in the back or neck, with a history of pain lasting almost every day for at least 3 months (n = 794). Physical activity data was categorized as ‘moderate’ or ‘vigorous’ activity in the NHANES dataset, and reported as daily minutes; minuets of sedentary behaviors was also reported. Dietary data was collected using 24hour-recall. All data were analyzed using SAS 9.4 survey procedures to account for the complex survey design of the NHANES. RESULTS: Chronic pain was not associated with differences in amount of time engaged in moderate or sedentary activities. Chronic pain was associated with multiple differences in dietary intake compared to a representative sample of US adults. Differences were noted in macro- and micronutrient intake, as well as dietary pattern differences. Individuals with chronic pain reported higher intakes of total fat and added sugars (P = 0.003); and lower intakes whole grains and fiber (P = 0.01), and were found to consume 32% less fruit (P = 0.05) resulting in lower intake of beta-carotene (∼1700 vs 2100 mcg, P = 0.01). Though chronic pain was associated with higher overall fat intake, no difference in intakes mono- and polyunsaturated fats were observed. CONCLUSIONS: This study supports prior research demonstrating that chronic pain is associated with dietary patterns that are higher in total fat and sugar, and lower in fiber and micronutrients. Additional research is needed to evaluate whether dietary interventions can improve chronic pain status. FUNDING SOURCES: None.

OBJECTIVES: There is a myth that obesity equals overnutrition. We conducted a study to examine whether obese people had a higher chance of adherence to recommended daily intake. METHODS: A retrospective cross-sectional study was conducted using data from the Nutrition and Health Survey in Taiwan (NAHSIT) 2014–2016. NAHSIT is a nationwide representative survey aimed to investigate and monitor the nutritional status of Taiwanese people. Fourteen nutrient intakes, including vitamin A, C, D, E, B1, B2, B3, B6, B12, Fe, Mg, Zn, Ca, and P, were evaluated using 24-hour dietary recall. Logistic regression models will be used to determine whether obesity was related to the higher chance of adherence to recommended daily intakes. Stratified analyses were conducted by sex. Obese (body mass index (BMI) ≥ 27 kg/m(2)) and normal-weight (18.5 kg/m(2) ≤ BMI

OBJECTIVES: Artificial rearing of pigs provides a number of advantages over conventional rearing (i.e., true maternal care), including careful control of nutrient intake and environment conditions. Yet there remains a gap in knowledge when comparing brain development between sow-reared and artificially-reared domestic pigs. Thus, our research sought to model brain development and assess recognition memory in a longitudinal manner by directly comparing rearing environments. METHODS: Forty-four intact (i.e., not castrated) male pigs were artificially-reared or sow-reared from postnatal day 2 until postnatal week 4. After postnatal week 4, all pigs were housed in a group setting within the same environment until postnatal week 24. Magnetic resonance imaging was conducted on pigs at 8 longitudinal time-points to model developmental trajectories of brain macrostrutural and microstructural outcomes. Additionally, pigs behavior were tested using the novel object recognition task at postnatal weeks 4 and 8. RESULTS: Throughout the 24-week study, no differences between rearing groups were noted in weekly body weights, average growth and feed intake patterns, or feed efficiency. Whole brain, grey matter, white matter, and cerebrospinal fluid growth patterns also did not differ between pigs assigned to different early-life rearing environments. Moreover, minimal differences in regional absolute volumes and fractional anisotropy developmental trajectories were identified, though artificially-reared pigs exhibited higher initial rates of myelination in multiple brain regions compared with sow-reared pigs. Furthermore, behavioral assessment at both PNW 4 and 8 suggested little influence of rearing environment on recognition memory, however, an age-dependent increase in object recognition memory was observed in the sow-reared group. CONCLUSIONS: Our findings suggest that early-life rearing environment has little influence on brain growth trajectories and behavior in the domestic pig. Artificial rearing may promote maturation in certain brain areas but does not appear to elicit long-term effects in outcomes including brain structure or behavior.
