English language education nowadays is not merely about the instruction and acquisition of linguistic knowledge and skills. Instead, it has progressed to the real-life applications of the target language, which further requires a mastery of cultural knowledge and skills. In terms of culture, English as a Foreign Language (EFL) learners, compared to native speakers of English, own their unique native culture. Yet, since language teachers tend to focus on the delivery of English cultural knowledge, EFL learners' native culture is sometimes shadowed in the mainstream English classrooms worldwide. To this end, this exploratory paper aims to advocate attention to the importance of EFL learners' native culture awareness and share some practical teaching and learning experiences in an English course called "Multimedia and Foreign Language Learning." The paper outlines the pedagogical design of the course in China, providing classroom examples and practical suggestions to course designers, educators and instructors. We expect to give insights into integrating native culture into foreign language education in university settings.

Nowadays, unhealthy dietary habits, insufficient food knowledge, and lack of manual skills are typical issues among primary and secondary school students in China. To help students build up a strong constitution and life wisdom, Weifang Hansheng School of Shandong developed a food education course. This paper expounds on the course framework, contents of food education textbooks and the measures to implement the course.

Using interview data from 11 international students, this paper compares international students' experiences at a single American university, and the acculturation issues that they encountered. The students assessed their experiences at the university, both positive and negative, and discussed their perceptions of American ways of doing things. The findings suggest that, when compared to students from other countries, students from China face considerable more difficulties both academically and socially, given the formidable language and cultural barriers. These challenges remain regardless of whether the students self-segregate with co-nationals or associate primarily with Americans. While individual-level factors (e.g., language fluency and coping ability) affect the international students' lived experiences and perceived satisfaction level while studying in the United States, this paper argues that environmental factors (e.g., the culture and reception of the host society) may be more important in shaping the experiences of international students, whether for better or worse.

Chinese enterprise personnel are faced with the problem of intercultural adaptation. Based on Black's theory of "three-dimensional" model of intercultural adaptation, this paper proposes a "four-dimensional" model of intercultural adaptation, namely, life adaptation, work adaptation, interpersonal adaptation and Chinese image adaptation. The research method of semi-structured in-depth interview is used to interview 23 Chinese people from one Chinese enterprise in Saudi Arabia, who have worked there for at least one year. We get findings as follows: (1) Life adaptation: maladjustment is mainly reflected in religious restriction. Especially, religious regulations and taboos make the life of Chinese enterprise personnel restricted. However, there are also many aspects of adaptation, such as Saudi cuisine, living environment and leisure life, which bring the satisfaction of life demands to Chinese enterprise personnel. (2) Work adaptation: foreign companies must employ a certain proportion of local people to work in their companies; the roles of buyers and sellers in Saudi Arabia and in China are different; the concept of time is different. (3) Interpersonal adaptation: Chinese people in Saudi Arabia still have the most frequent contact with their Chinese compatriots, and it is difficult for them to develop close friendship with foreigners. Chinese people are good at creating harmonious interpersonal relationships for work through some after-work activities, such as drinking tea, eating out and holding football matches. (4) Chinese image adaptation: Chinese enterprise personnel in Saudi Arabia have decent income, and Saudi police fail to check Chinese cars, all of which make the Chinese people have a positive face value. In view of the above four adaptation situations of Chinese enterprise personnel in Saudi Arabia, the following suggestions are proposed: (1) Be strict with yourself in life, respect local social and religious customs, and also keep a careful attitude and actively deal with disadvantageous factors. (2) While benefiting from working or doing business in Saudi Arabia, we should make contributions for the development of local economy and society, providing employment and training for local people. (3) We should observe the local laws and regulations, and also follow the local and international market rules. (4) In interpersonal communication, we should combine the maintenance mode of Chinese "guanxi" (relationship) with western "principle" on the one hand, and make a difference between them on the other hand. (5) In terms of image adaptation, besides maintaining a good image politically and economically, it is also necessary to improve our individual quality and our cultural cultivation overseas, be a communicator bridging Chinese and foreign excellent culture, and build a positive national image and individual image.

The Food Safety Knowledge Network (FSKN) is a collaboration between Michigan State University, the Global Food Safety Initiative of the Consumer Goods Forum, and other food industry and public sector partners. FSKN's goal is to help strengthen the food industry's response to the complex food safety knowledge and training challenges that affect emerging markets by providing free access to high-quality, standardized learning resources. The resources were designed to be available on demand and as a structured learning experience which can support face-to-face training and fully online training. The pilots thus far have shown that participants in FSKN training demonstrate a significant increase in knowledge. The paper will share the processes used to set up an efficient open educational resources initiative including understanding licensing, using open software, establishing competencies and working with corporate and other international partners.

This study assessed the techno-economic feasibility of a biorefinery for valuable by-products (mainly hydrogen, ethanol and fertilizer) generation from food waste. The plant was designed to be built in Zhejiang province (China) with a processing capacity of 100 t food waste per day. It was found that the total capital investment (TCI) and annual operation cost (AOC) of the plant were US$ 7625549 and US$ 2432290.7 year -1 , respectively. After the tax, US$ 3141867.6 year -1 of net profit could be reached. The payback period (PBP) was 3.5 years at a 7% discount rate. The internal rate of return (IRR) and return on investment (ROI) were 45.54% and 43.88%, respectively. Shutdown condition could happen with the feed of food waste less than 7.84 t day -1 (2587.2 t year -1 ) for the plant. This work was beneficial for attracting interests and even investment for valuable by-products generation from food waste in large scale., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Ensuring food and nutrient supply is a crucial aspect of achieving food safety. With rapid population growth, urbanization, and social and economic development, the challenges related to China's food and nutrient production have become increasingly prominent. This paper analyzed the characteristics of the spatiotemporal pattern evolution of food and nutrient production in China from 1995 to 2020, utilizing the conversion of various food nutrients and the establishment of a gravity center model. The results showed that: (1) Food production exhibited increasing trends in China, six regions, and 90% of the provinces. Notably, the structure of food production underwent significant changes in China, East China, Central-South China, Southwest China, Northwest China, and 60% of the provinces. (2) The output of all categories of food nutrients demonstrated increasing trends in China, six regions, and most provinces. At three different geographical scales, the changes of six food nutrients production structure showed significant differences. (3) Natural, political, social, economic, and technological factors played pivotal roles in influencing the gravity centers of food and nutrient production in China. The gravity centers of cereal production shifted northeast, while those of root and tuber, oil crops, and stimulants production moved westward. Additionally, the gravity centers of sugar crop, pulse, vegetable, fruit, and aquatic product production moved southwest and those of livestock and poultry production shifted northward. (4) Affected by the food production, the gravity centers of food energy, food protein, and food carbohydrate production shifted northward, while those of food fat, food vitamins, and food minerals production shifted northwest, southwest, and westward, respectively. The results of this study are of great significance for policy adjustments pertaining to the distribution pattern of food production, food security stability, and sustainable development in China.

Internet coupled with agricultural development in full swing, green agri-food product e-commerce has become a hot topic in the development of e-commerce. However, due to the seasonality, territoriality, weak quality, difference, and dispersion of agri-food products, e-commerce of green agri-food products are facing difficulties. Based on the gap between consumers' willingness and behavior to buy green agri-food products online, this paper quantitatively studied the factors that affect consumers' behavior deviation to buy green agri-food products online. The method of constructing the binary Logistic regression model was adopted, and analysis tools such as SPSS and Excel were used for analysis, to study the influence of various factors on consumers' purchase willingness and behavior. The research conclusion shows that: consumers' gender, age, understanding of online agri-food products, and monthly disposable income have a positive impact on the consistency of consumers' behavior and willingness, while the price of green agri-food products and online purchasing frequency have a negative impact on consumers' willingness and behavior of online purchasing. The results are discussed in the context of existing studies. Suggestions and research prospects are presented at the end of the article., Competing Interests: The authors have declared that no competing interests exist.

Reactive nitrogen (Nr) has far-reaching advantages and disadvantages on human beings. Nitrogen footprint (NF) is a tool to quantify the use of Nr in the environment. Food nitrogen footprint (FNF) accounts for the largest proportion of the total NF, and the differences between provinces in China exist objectively. In order to explore the spatial correlation and socio-economic driving factors of China's FNF, this paper uses N-calculator tool to calculate the FNF of 30 provinces in China from 2000 to 2018, and uses exploratory spatial data to analyze the spatial correlation and changes of provincial FNF, The driving factors and spatial effects of FNF change in the province were analyzed by using spatial Durbin panel model and spatial regression partial differential method. The results showed that: (1) There is a significant and stable positive spatial dependence and heterogeneity in the FNF among provinces; (2) The direct effect factors of promoting the growth of FNF in the province are urban household Engel coefficient, per capita disposable income of rural residents and rural household Engel coefficient. The main factors of restraining the growth of FNF in the province are wastewater discharge per unit GDP and per capita GDP; (3) the spillover effect is mainly manifested as the negative effect of the increase of urban household Engel coefficient on neighboring provinces, and the spillover effect of per capita disposable income of urban residents and nitrogen fertilizer application rate per unit grain yield on the growth of FNF of neighboring provinces is significant. From the policy level, it is necessary to guide healthy and scientific eating habits, reduce the proportion of meat and fish in the diet structure, reduce the nitrogen fertilizer application per unit grain yield, and improve the efficiency of chemical fertilizer utilization. When formulating relevant policies, government departments should give consideration to the cooperation between provincial and regional governments., (Copyright © 2021 Elsevier Inc.

Drawing on a recent online survey combined with city-level data, this paper examines the impact of the COVID-19 on consumers' online food purchase behavior in the short term. To address the potential endogeneity issues, we adopt an instrumental variable (IV) strategy, using the distance from the surveyed city to Wuhan as the instrumental variable. We show that our IV method is effective in minimizing potential bias. It is found that the share of confirmed COVID-19 cases increases the possibility of consumers purchasing food online. This is more likely to be the case for young people having a lower perceived risk of online purchases and living in large cities. Despite some limitations, this paper has policy implications for China and other countries that have been influenced by the COVID-19 epidemic. Specifically, government support and regulation should focus on (i) ensuring the safety of food sold on the internet, (ii) protecting the carrier from becoming infected, and (iii) providing financial support to the poor since they may have difficulties in obtaining access to food living in small cities. Moreover, how to help those who are unable to purchase food online because of their technical skills (e.g., the elderly who are not familiar with smart phones or the internet) also deserves more attention for the government and the public., Competing Interests: The authors have declared that no competing interests exist.

To balance the supply and demand in China's beef market, beef consumption must be scientifically and effectively forecasted. Beef consumption is affected by many factors and is characterized by gray uncertainty. Therefore, gray theory can be used to forecast the beef consumption, In this paper, the structural defects and unreasonable parameter design of the traditional gray model are analyzed. Then, a new gray model termed, EGM(1,1,r), is built, and the modeling conditions and error checking methods of EGM(1,1,r) are studied. Then, EGM(1,1,r) is used to simulate and forecast China’s beef consumption. The results show that both the simulation and prediction precisions of the new model are better than those of other gray models. Finally, the new model is used to forecast China’s beef consumption for the period from 2019–2025. The findings will serve as an important reference for the Chinese government in formulating policies to ensure the balance between the supply and demand for Chinese beef. [ABSTRACT FROM AUTHOR]

In China, food safety problems have occurred frequently in the past ten years, causing great concern for the public. Adolescents, with higher exposure to problematic food, represent a unique target for interventions aimed at risk reduction. To understand their food safety knowledge, attitude and practice, a cross-sectional survey using paper questionnaire was carried out among 4,220 students (median age of 14 years, 50.3% females) from nine secondary schools in 3 districts of Beijing. The findings showed that the majority of respondents (42.0%) had a high knowledge level. Significant association was found between food safety knowledge score (median = 11, IQR:9–13) and demographic characteristics of region, school type, residence type, habit of smoking and alcohol use, academic record and parents’ education background. In terms of attitude and practice, only 17% of those surveyed regarded China’s food safety situation as good, 53.6% regarded it as worrying; almost all students (96.5%) did pay attention to food safety; 95.3% of the students had worried about the safety of the food provided by the small restaurants and street peddlers, but in reality, as many as 69.4% often or occasionally bought food from peddlers around their campuses and nearly half continued the consumption of such food in spite of worrying about its safety problems. Overall, the food safety knowledge among Beijing secondary school students was relatively good. They did not show much confidence in the country’s food safety situation, but many aware of the safety issues did not bother to change or take action. The study suggests that more systematic and targeted education on food safety is necessary for this age group. [ABSTRACT FROM AUTHOR]

For most of its history, China has supported a growing population through food systems which have been mutually inclusive of people and their locality. This trajectory has required adequate ecosystem maintenance or humanised reformulation and a high degree of recyclable nutrient flow. The 'tipping point' in habitat sustainability has come with the size and demographic structure of China's population to one that is ageing, with modernisation of its infrastructure and increased expectations of better livelihoods, standards of living and health. In order to meet these expectations, China has embarked on rapid urbanisation for upwards of 300 million people over the next 15-20 years and to do so taking account of the environmental limitations. The process will radically change rural as well as urban China and the systems which connect them. Chief among these will be ecosystems in number and type along with the food and health systems integral to them. To minimise ecological damage and optimise the benefits to people and place, describing, monitoring and managing the process will be paramount. The present paper is a situational analysis of health as it may be ecologically favoured or disordered (Ecosystem Health Disorders) and of the food systems on which the environment and health depend. An effort is made to enumerate the current situation in China in a way that might enable the optimisation of humanised ecosystems.

Background: Homegardens are small-scale land use systems with significant implications for local livelihoods, biodiversity conservation, and sustainable development due to their diverse flora and fauna. Conducting homegarden surveys enables researchers to gain insights into the traditional ecological knowledge of indigenous communities, preserve homegarden biodiversity, and promote sustainable livelihoods. This study has two objectives: first, to collect, record, and organize data on homegarden plants and related traditional knowledge from three communities in the Laershan Plateau, and second, to analyze the species and functional diversity of homegarden plants in the region while exploring the factors that contribute to the heterogeneous distribution of these plants among the communities of three townships. Methods: This research employed field surveys in the Laershan Miao Autonomous Region in Xiangxi, China, from September 2021 to August 2023. Data were collected through observation and semi-structured interviews. The study utilized descriptive statistics and quantitative analysis, including the Relative Importance Value (RI), Use Value Index (UV), Jaccard Index (JI), and Comprehensive Index of Land Use Degree (La), to examine the diversity of local homegarden plants and related traditional knowledge, as well as community heterogeneity. Results: The study area exhibited rich biodiversity, with 152 plant species recorded belonging to 62 families and 124 genera. These findings highlight the importance of homegarden plants in maintaining ecological balance and enhancing system resilience against disturbances. Homegarden plants serve multiple functions such as food, ornamental, medicinal, and fodder purposes, with edible and trade plants having the most abundant knowledge. Furthermore, this research revealed that communities with similar forest resource compositions may have similar homegarden plant compositions, demonstrating the connection between cultural exchange among different communities and patterns of plant species distribution. Conclusions: The Laershan region boasts diverse homegarden plant species crucial for ecological balance and resilience. Their multifunctionality reflects human impact. Plant diversity varies with residents' lifestyles, needs, and cultural exchanges. The close connection between plants and local life is clear. Factors like resource distribution, cultural exchange, and lifestyle influence plant distribution. Further research is needed for conservation and sustainable development. Future research should focus on culturally valuable plant species and traditional knowledge applications. [ABSTRACT FROM AUTHOR]

The objective of the present paper is to provide glycaemic index (GI) and glycaemic load (GL) values for a variety of foods that are commonly consumed in Hong Kong and expand on the international GI table of Chinese foods. Fasted healthy subjects were given 50 g of available carbohydrate servings of a glucose reference, which was tested twice, and test foods of various brands of noodles (n 5), instant cereals (n 3) and breads (n 2), which were tested once, on separate occasions. For each test food, tests were repeated in ten healthy subjects. Capillary blood glucose was measured via finger-prick samples in fasting subjects ( - 5, 0 min) and at 15, 30, 45, 60, 90 and 120 min after the consumption of each test food. The GI of each test food was calculated geometrically by expressing the incremental area under the blood glucose response curve (IAUC) of each test food as a percentage of each subject's average IAUC for the reference food. GL was calculated as the product of the test food's GI and the amount of available carbohydrate in a reference serving size. The majority of GI values of foods tested were medium (a GI value of 56-69) to high (a GI value of 70 or more) and compared well with previously published values. More importantly, our dataset provides GI values of ten foods previously untested and presents values for foods commonly consumed in Hong Kong.

This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.

There has been a rapid and remarkable recovery in Hangzhou, Zhejiang Province, China, during the 1990s, of a distinctive cuisine whose origins can be traced back to, at least, the building of the Grand Canal between Beijing and Hangzhou in the 600s AD and the stimulus to trade and migration, that was provided. This, along with exceptional health indices in the region, provides a basis for a new integrative study of the food chain, food culture and food science in regard to the human condition, which would be manifest by the degree of environmental sustainability, economic progress, social cohesion, health status, well-being and happiness that these dimensions of "food for humans " should support. Collectively, these have rarely been subject to systematic scholarly pursuit. Through the endeavours of the Zhejiang Association for Science and Technology, representing some 150,000 professionals and the international community, represented principally by the International Union of Nutritional Sciences (IUNS) and its partners in WHO, the FAO Network of Excellence and the Hangzhou University of Commerce, this field has been brought together through the papers in this issue of Asia Pacific Journal of Clinical Nutrition. The report builds on related endeavours in recent times, notably 'The Okinawan Roundtable on Nutrition and Cardiovascular Disease' which recognizes the exceptional and distinguishing features of the Okinawan diet in health protection, and the assessment of the place of fatty fruits, like red palm fruit amongst 'North and West African Foods'.

From ancient wisdom to modern science and technology, Chinese cuisine has been established from a long history of the country and gained a global reputation of its sophistication. Traditional Chinese foods and cuisine that exhibit Chinese culture, art and reality play an essential role in Chinese people's everyday lives. Recently, traditional Chinese foods have drawn a great degree of attention from food scientists and technologists, the food industry, and health promotion institutions worldwide due to the extensive values they offer beyond being merely another ethnic food. These traditional foods comprise a wide variety of products, such as pickled vegetables, salted fish and jellyfish, tofu and tofu derived products, rice and rice snack foods, fermented sauces, fish balls and thousand-year-old eggs. An overview of selected popular traditional Chinese foods and their processing techniques are included in this paper. Further development of the traditional techniques for formulation and production of these foods is expected to produce economic, social and health benefits.

This paper discusses the significance of the food industry for the Zhejiang provincial economy and for provincial economies generally. It is suggested that the strong ties between the food industry and provincial economies in China means that the food industry can be a key influence in the economic development of regional China. Moreover, the geographically diffuse nature of the food industry in China gives the industry a strategic significance in countering regional inequality within and between provinces, a by-product of China's rapid growth over the past 25 years. For these reasons, change in the food industry, whether it has its origins in the introduction of western fast foods, or in environmental, technological or economic trends, not only assumes significance for the health of the Chinese people (as other papers presented to the International Cuisine and Health Workshop at Hangzhou have pointed out), but also for the wealth of the nation and the way that wealth is distributed.

Carbon footprint labels allow manufactures to show information about the impact that their food production has on the environment, as well as to help consumers make more sustainable choices. Thus, investigating consumers' reaction towards carbon footprint labels is vital to understand their effectiveness. The aim of this manuscript is to identify the state of the art and research gaps on this topic, by conducting a literature review of published scientific article between 2011 and 2020. In total, 38 papers emerged. Findings show that females, adults, with higher income and educational level have a more positive attitude towards carbon footprint labels. Furthermore, people expressing higher environmental concern and those who are used to buy eco-friendly labelled foods are willing to pay more for carbon footprint labelled foods. However, it also emerges that consumers still have poor knowledge of carbon measurements and the existing carbon footprint label system is still unclear. When carbon footprint labels are re-designed using consumers friendly symbols (e.g., traffic light colours), consumers' understanding significantly increases. Consumers from countries like Egypt and China also show a positive attitude towards carbon footprint information, meaning that a carbon footprint label system should be developed also in the emerging countries. Nonetheless, when carbon footprint is presented with other labels (e.g., organic, Fair Trade etc.) consumers show the lowest willingness to pay for carbon footprint information. It was also found that using a carbon footprint label on environmentally sustainable produced foods (e.g., using upcycled ingredients) increses willingness to pay. Food manufacturers should better inform consumers on carbon footprint labels and policy makers are advised to develop a consumers friendlier carbon footprint label system to incentivize more sustainable choices. This paper is the first to summarize existing literature on consumers' behaviour for carbon footprint labelled foods, providing a discussion of the implications for food manufacturers and policy makers, as well as future research avenues. • 38 research articles on consumer behaviour for carbon footprint labelled foods were investigated. • Concern towards environmental conditions influence consumers attitude for carbon footprint labels. • Lack of knowledge towards carbon footprint label system emerged. • There is need to develop a commonly recognized footprint label to better drive sustainable choices. • Industry implications and future research avenues are discussed.

It has been suggested that added sugar intake is associated with non-alcoholic fatty liver disease (NAFLD). However, previous studies only focused on sugar-sweetened beverages; the evidence for associations with total added sugars and their sources is scarce. This study aimed to examine the associations of total added sugars, their physical forms (liquid v. solid) and food sources with risk of NAFLD among adults in Tianjin, China. We used data from 15 538 participants, free of NAFLD, other liver diseases, CVD, cancer or diabetes at baseline (2013–2018 years). Added sugar intake was estimated from a validated 100-item FFQ. NAFLD was diagnosed by ultrasonography after exclusion of other causes of liver diseases. Multivariable Cox proportional hazards models were fitted to calculate hazard ratios (HR) and corresponding 95 % CI for NAFLD risk with added sugar intake. During a median follow-up of 4·2 years, 3476 incident NAFLD cases were documented. After adjusting for age, sex, BMI and its change from baseline to follow-up, lifestyle factors, personal and family medical history and overall diet quality, the multivariable HR of NAFLD risk were 1·18 (95 % CI 1·06, 1·32) for total added sugars, 1·20 (95 % CI 1·08, 1·33) for liquid added sugars and 0·96 (95 % CI 0·86, 1·07) for solid added sugars when comparing the highest quartiles of intake with the lowest quartiles of intake. In this prospective cohort of Chinese adults, higher intakes of total added sugars and liquid added sugars, but not solid added sugars, were associated with a higher risk of NAFLD.

Climate change is a major source of external shocks to the economy. In this article, we estimate the short‐term impacts of tropical storms on food prices. After matching the track records of tropical storms with retail prices of food products during 1998 and 2012 in China, we find that tropical storms lead to food prices increasing by 2.3%, and the effect lasts more than one month. The positive impacts on prices mainly concentrate on fresh vegetable products. One main channel of price increases caused by tropical storms is the supply‐side shock to the transportation and distribution system. We find limited evidence of price increases driven by demand‐side shocks such as food displacement and food composition changes. The impacts of tropical storms on food price increases lead to a total loss amounting to $92 million each year on average. This study contributes to literature evaluating the price impacts caused by tropical storms and provides policy implications on enhancing food supply resilience. [ABSTRACT FROM AUTHOR]

Various theories and approaches have been introduced in the debate on how to address sustainable consumption. In this study, we first discuss different theoretical perspectives on sustainable consumption, particularly developed in the fields of economics, social psychology and environmental sociology. We argue that neither an ‘individualist’ nor a system- or structural perspective alone is sufficient for understanding and analysing the transition towards sustainable consumption. Therefore, we propose to apply the Social Practices Approach (SPA) that combines both human agency and social structures to understand sustainable consumption issues. Following the SPA framework, we review and summarize research on sustainable consumption in China in particular on three consumption fields: food, housing energy and mobility. It is found that introducing more efficient production technology is commonly taken as the focal point in these sectors when sustainable consumption was introduced to China. Despite a rising interest in consumers' perceptions of products' sustainability in recent years, research has rarely paid any attention to consumers' behavioural change or to the transition dynamics towards sustainable consumption. In general, ‘individualist’ perspectives have largely dominated Chinese sustainable consumption research. This paper proposes to move attention to a better understanding of Chinese consumption issues by emphasizing the link between the provision of sustainable products and the diverse sustainable consumption practices. Also, images of food, energy, mobility and other consumption products that are undergoing transitions need to be considered in future research as these have consequences for socio-technical changes, material infrastructures and for ‘lifestyle’ innovations.

Anthropogenic climate change appears to be increasing the frequency, duration and intensity of extreme weather events. Such events have already had substantial impacts on socioeconomic development and population health. Climate change's most profound impacts are likely to be on food, health systems and water. This paper explores how climate change will affect food, human health and water in China. Projections indicate that the overall effects of climate change, land conversion and reduced water availability could reduce Chinese food production substantially -- although uncertainty is inevitable in such projections. Climate change will probably have substantial impacts on water resources -- e.g. changes in rainfall patterns and increases in the frequencies of droughts and floods in some areas of China. Such impacts would undoubtedly threaten population health and well-being in many communities. In the short-term, population health in China is likely to be adversely affected by increases in air temperatures and pollution. In the medium to long term, however, the indirect impacts of climate change -- e.g. changes in the availability of food, shelter and water, decreased mental health and well-being and changes in the distribution and seasonality of infectious diseases -- are likely to grow in importance. The potentially catastrophic consequences of climate change can only be avoided if all countries work together towards a substantial reduction in the emission of so-called greenhouse gases and a substantial increase in the global population's resilience to the risks of climate variability and change.

Objective Benzyl butyl phthalate (BBP) is a plasticizer used in food contact materials. Dietary exposure to BBP might lead to reproduction and developmental damages to human. The present paper was aimed to assess the health risk of BBP dietary exposure in Chinese population. Methods The BBP contents were detected in 7409 food samples from 25 food categories by gas chromatography-mass spectrometry operated in selected ion monitoring (SIM) mode. The dietary exposures of BBP in different age and sex groups were estimated by combining the content data with food consumption data derived from 2002 China National Nutrient and Health Survey, and evaluated according to the tolerable daily intake (TDI) of BBP established by European Food safety Agency. Results It was found that BBP was undetectable in most samples and the highest level was 1.69 mg/kg detected in a vegetable oil sample. The average dietary exposure of BBP in people aged ≥2 years was 1.03 μg/kg bw per day and the highest average exposure was found in 2–6 years old children (1.98 μg/kg bw per day). The BBP exposure in 7-12 months old children excessed 10% of tolerable daily intake (TDI) in worst scenario. Conclusion The health risk of BBP dietary exposure in Chinese population is low and, considering BBP alone, there is no safety concern. [ABSTRACT FROM AUTHOR]

Background: Cross-reacting carbohydrate determinants (CCD) exist in some pollen and food allergens, but they do not contribute to allergic symptoms. However, CCD can induce specific IgE (sIgE) production and may lead to incorrect allergen diagnosis and treatment. CCD inhibitor is a specific antibody adsorbent which can preclude CCD from binding to sIgE. Currently, the data of CCD inhibition in allergen sIgE test are limited. Methods: The allergic patients with positive skin prick reactions to two or more pollen and/or food allergen extracts were included in our study. Their sera were obtained and sIgE was tested with an allergen panel that included 29 single and mixed allergens (MEDIWISS Analytic GmbH, China) before and after CCD inhibition. The changes of sIgE against these allergens and the correlations of sIgEs to clinical symptoms were analyzed. Results: A total of 44 patients were included and 36 (81.82%) of those were multi-sensitized to house dust mites and pollen allergens based on skin prick tests. The sIgE levels and positive rates against most pollen and food allergens were significantly lower after CCD inhibition. The sIgE levels of pollen were positively correlated to those of food allergens before CCD inhibition. However, these correlations were weakened or no longer existed after CCD inhibition. The sIgE against pollen and food allergens showed significantly higher consistency with clinical symptoms after CCD inhibition. Conclusion: Cross-sensitization caused by CCD is widespread in pollen and food. CCD inhibition test can improve the diagnostic accuracy of pollen and food allergy. [ABSTRACT FROM AUTHOR]

Recently, research of whole grain mainly focuses on rice and wheat, while less on millet. Millet whole grain's research and development lag behind. In this paper, the opinion that millet is an important member of whole grain family is provided based on the definition of whole grain and China's national conditions. Moreover, millet whole grain food has great development potential in China. The development direction of millet whole grain is put forward based on the current status and analysis of millet processing. [ABSTRACT FROM AUTHOR]

Rice-crayfish system has been extensively promoted in China in recent years. However, the presence of toxic elements in soil may threaten the quality of agricultural products. In this study, eight toxic elements were determined in multi-medium including soil, rice, and crayfish from the rice-crayfish system (RCS) and conventional rice culture (CRC) area. Crayfish obtained a low level of toxic element content, and mercury (Hg) in rice from RCS showed the highest bioavailability and mobility. Health risk assessment, coupled with Monte Carlo simulation, revealed that the dietary exposure to arsenic (As) and Hg from rice and crayfish consumption was the primary factor for non-carcinogenic risk, while Cd and As were the dominant contributors to the high carcinogenic risk of rice intake for adults and children, respectively. Based on the estimated probability distribution, the probabilities of the total cancer risk (TCR) of rice intake for children from RCS were lower than that from CRC. [ABSTRACT FROM AUTHOR]

Abstract: Increasing fertilizer phosphorus (P) application in agriculture has greatly contributed to the increase of crop yields during the last decades in China but it has also increased P flows in food production and consumption. The relationship between P use efficiency and P flow is not well quantified at national level. In present paper we report on P flows and P use efficiencies in rice, wheat, and maize production in China using the NUFER model. Conservation strategies for P utilization and the impact of these strategies on P use efficiency have been evaluated. Total amounts of P input to wheat, rice, and maize fields were 1095, 1240, and 1128Gg, respectively, in China, approximately 80% of which was in chemical fertilizers. The accumulation of P annually in the fields of wheat, rice, and maize was 29.4, 13.6, and 21.3kgha−1, respectively. Phosphorus recovered in the food products of wheat, rice, and maize accounted for only 12.5%, 13.5%, and 3.8% of the total P input, or 3.2%, 2.6%, and 0.9% of the applied fertilizer P, respectively. The present study shows that optimizing phosphorus flows and decreasing phosphorus losses in crop production and utilization through improved nutrient management must be considered as an important issue in the development of agriculture in China.

Resolving inventory and location problems is the most important and fundamental tactical decision in the initial stages of developing a distribution network design. This is especially true for a logistics system dealing with perishable food. To minimise both the total inventory transportation cost of fresh agri-products and also waste in the supply chain, the evolution of the food supply chain structure is analysed and an inventory location allocation model is presented describing the real-life problem. The key issues are to describe food demand distribution and to determine the balance of transportation and inventory cost. To improve the quality of the solution, a local search is embedded in the two-grade delayed particle swarm optimisation. Experimental results demonstrate the algorithm can effectively resolve conflict between different costs and improve development decisions regarding Beijing's perishable food distribution centres.

Introduction. Global population has witnessed significant changes in the way food is produced and consumed. Although this has benefitted population health, it has also contributed to climate change and unsustainable use of natural resources. Materials and methods. Comprehensive literature review. Results and discussion. The characteristics of four transition theories related to food are outlined to help explain population behaviour, namely demographic, nutrition/protein, food and sustainability transition. This is followed by a further desktop analysis of the changes occurring in China, the world's largest demography, and this country's contribution to a mostneeded global sustainability transition. The theoretical framework of transition theories used since the mid- 20th century outlines changes in population behaviour impacting relationships between people and more recently with the natural environment. As a multidisciplinary field describing fundamental shifts in human societies, transition theories are very insightful in relation to food and nutrition. The demographic transition links industrialisation with fertility and mortality rates but also with food availability. During the nutrition transition, a change occurs in people's calorie intakes from different food groups. While the share of protein remains relatively stable, the initial transition from plant- to animal-based foods now changes in reverse with increasing ecological and health awareness. This nutrition/protein transition can result in a better dietary behaviour with reduction in over-consumption, losses and waste. The food transition explains the transformations on the supply side - how food is produced, processed and distributed, reflecting changes in agricultural methods, use of land, soil, water, fertilisers and chemicals, supply and distribution chains. More sustainable farming methods are currently being introduced in response to ecologically threatening trends as a result of land-use changes and use of chemicals. As distinct from the other concepts, sustainability transition does not describe an evolutionary pattern of changes but only the current most necessary transformation in development. It requires radical transformation and action towards reduced environmental footprints of all human activities, including food. China's development has experienced similar transitions although with unique features. Its demographic transition has been influenced by the "one child policy" while the nutrition/protein transition has been fuelled by increasing income levels. Industrialisation of food production with application of chemicals is widespread but more recently, organic methods of farming are gaining momentum. Food security and production are recognised as a challenge and opportunity in China's sustainability transition with state-driven dietary efforts to contain domestic meat consumption. Conclusion. China has the opportunity to play a prominent role in the global transition to improved food choices, as required by the current environment and climate emergency, by shifting its own eating habits and also contributing to the burgeoning field of new alternatives to livestock products.

Near-infrared spectroscopy (NIR) is a non-destructive, fast, and low-cost method to measure the grain quality of different cereals. However, the feasibility for determining the critical biochemicals, related to the classifications for food, feed, and fuel products are not adequately investigated. Fourier-transform (FT) NIR was applied in this study to determine the eight biochemicals in four types of sorghum samples: hulled grain flours, hull-less grain flours, whole grains, and grain flours. A total of 20 hybrids of sorghum grains were selected from the two locations in China. Followed by FT-NIR spectral and wet-chemically measured biochemical data, partial least squares regression (PLSR) was used to construct the prediction models. The results showed that sorghum grain morphology and sample format affected the prediction of biochemicals. Using NIR data of grain flours generally improved the prediction compared with the use of NIR data of whole grains. In addition, using the spectra of whole grains enabled comparable predictions, which are recommended when a non-destructive and rapid analysis is required. Compared with the hulled grain flours, hull-less grain flours allowed for improved predictions for tannin, cellulose, and hemicellulose using NIR data. This study aimed to provide a reference for the evaluation of sorghum grain biochemicals for food, feed, and fuel without destruction and complex chemical analysis. [ABSTRACT FROM AUTHOR]

Italian Sounding—i. e., the Italian appearance of a product or service brand irrespective of its country of origin—represents a global market phenomenon affecting a wide range of economic sectors, particularly the agro-food sector. Although its economic impact has been repeatedly stressed from different points of view (policy, economy, culture, etc.), systematic scientific knowledge regarding its social–psychological bases is lacking. Three studies carried out in three different countries (Italy, China, and USA) address this literature gap. Different consumer groups (both native and/or non-native) are targeted regarding major product categories pre-selected categories, which are the major Italian food goods within the specific country according to piloting (oil and/or pasta). In each study, the main independent variable (product version) has been manipulated by presenting real product images (previously pre-selected within the tested food category in each country market), whose "Italianness" degree is effectively manipulated by the main study variable (product version) across three or four levels (Protected Designation of Origin Made in Italy, Made in Italy, Italian Sounding, and Generic Foreign). Main hypotheses are tested via a survey with the specific product images administered to samples in Italy (N = 204, 148 Italians and 56 non-Italians), China (N = 191, 100 Chinese and 91 non-Italian expatriates in China), and the USA (N = 237 US citizens). Across the three studies, results show that Made in Italy products, compared to the other ones, are advantaged in terms of the main dependent variables: reputation profile, general reputation, attitude, and willingness to pay (WTP). Moreover, Italian Sounding products are endowed with corresponding significant advantages when compared to the Generic Foreign by non-Italian samples (although to a different degree according to the different sub-samples). Results reveal the specific social–psychological profile of Italian Sounding products in terms of either weaknesses or strengths when compared to both Made in Italy products and Generic Foreign ones, differently in the eyes of Italian and non-Italian consumers across different countries. Finally, consistently across the three studies, the extent to which a food product is perceived to be Italian increases consumers' WTP for that product, and this effect is consistently mediated by the product's reputation.

Backgrounds: Previous reports of foreign-body ingestion focused primarily on accidental ingestion and very few studies focused on intentional ingestion of foreign body (FB) in China. Our study aimed to compare the prevalence of different age, gender, types, locations and management of FB ingested between intentional ingestion and accidental ingestion of FB in Northern China.Methods: A retrospective case series studied all patients with suspected FB ingestion in Digestive Endoscopy Center of Beijing Friendship Hospital, between January 2011 and January 2019. The patients were divided into 2 groups. Group A included the patients who intentionally ingested FBs, and Group B included the patients who accidentally ingested FBs. Patients' database (demographics, past medical history, characteristics of FB, endoscopic findings and treatments) were reviewed. Statistical analyses were conducted using SPSS software.Results: Group A consisted of 77 prisoners, 2 suspects and 11 psychologically disabled persons. Group B consisted of 1020 patients with no prisoners, suspects or psychologically disabled persons. In Group A, there were no food-related foreign bodies, and the majority of FBs were metallic objects (54.44%). However in Group B, food-related FBs were the most common (91.37%). In Group A, 58 cases (64.44%) were located in the stomach, while in Group B, 893 cases (87.55%) were located in the esophagus (P < 0.05). 1096 patients successfully underwent endoscopic removal and 14 failed, including 9 cases in Group A and 5 cases in Group B. The duration of FBs impaction was longer in Group A than that in Group B (P < 0.05).Conclusions: In our study, the patients who intentionally ingested FB were mainly prisoners, FBs were mostly sharp metallic objects, the duration of FBs impaction was longer, and the rate of successful endoscopic treatment was lower than that of the general population. Attention should be focused on these patients. [ABSTRACT FROM AUTHOR]

Objective: Numerous systematic reviews of prospective studies on the association of stroke risk with the consumption of various food groups have been published. A review of the evidence across the existing systematic reviews and meta-analyses of prospective studies was conducted to provide an overview of the range and validity of the reported associations of food groups with stroke risk.Design: The PubMed, EMBASE and Cochrane Library databases were searched for articles published up to September 2015 to identify systematic reviews of prospective studies.Results: A total of eighteen studies published from 2008 to 2015 were eligible for analysis. Overall, thirteen specific foods were studied for an association with stroke outcome, including nuts, legumes, fruits and vegetables, refined grains, whole grains, dairy products, eggs, chocolate, red and/or processed meat, fish, tea, sugar-sweetened beverages and coffee. Whereas a high consumption of nuts, fruits, vegetables, dairy foods, fish and tea, and moderate consumption of coffee and chocolate demonstrated a protective effect, a high consumption of red and/or processed meat was associated with increased stroke risk. Refined grain, sugar-sweetened beverage, legume, egg and whole grain intake showed no effect on stroke outcome.Conclusions: The current overview provided a high level of evidence to support the beneficial effect of specific foods on stroke outcome. Clinicians and policy makers could inform clinical practice and policy based on this overview. [ABSTRACT FROM AUTHOR]

Background: Local people in the Himalayan region use a wide range of wild and non-cultivated edible plants (WNEPs) for food, spice, medicinal, and cultural purposes. However, their availability, use, status and contribution to livelihood security are poorly documented, and they have been generally overlooked in recent agro-biodiversity conservation and management programmes. The study aimed to investigate WNEP diversity and current status in a part of the Kailash Sacred Landscape--a transboundary landscape shared by Nepal, India and PR China--in terms of collection, use, management and conservation initiatives. Methods: Multiple methodologies and tools were used for data collection. A series of participatory tools (45 key informant interviews, 10 focus group discussions, a crop diversity fair, direct observation of species through a transect walk and rapid market assessments) was followed by a household survey (195 respondents) and complemented by a literature review. Results: The study recorded 99 WNEPs belonging to 59 families of which 96 were angiosperms, one gymnosperm and two pteridophytes. Species were used for food, spice, medicine, rituals and income generation. Thirty-five species had multiple uses, including these: 40 species were used for fruit and 31 for vegetables. WNEPs contribute significantly to daily food requirements, especially the vegetables. The use value of Dryopteris cochleata was found highest (0.98) among frequently used vegetable species. The values of informant consensus factor were found maximum for worms in the stomach (0.99) and minimum for skin disease treatment (0.67). Nearly 85% of households depended exclusively on WNEPs for at least more than a month per year. Results on the importance and use of different species, gender roles in WNEP activities and conservation approaches are presented. Conclusions: People living in the Kailash Sacred Landscape depend significantly on WNEPs, and this is especially critical in times of food shortage. The WNEPs have considerable potential as an important supplement to cultivated food crops. Farmers prioritise species with multiple use values and popular vegetables. However, there are numerous challenges and interventions needed to ensure conservation and management of species and their continued availability to support food security and local livelihoods.

Food and beverage marketing contributes to poor dietary choices among adults and children. As consumers spend more time on the Internet, food and beverage companies have increased their online marketing efforts. Studies have shown food companies' online promotions use a variety of marketing techniques to promote mostly energy-dense, nutrient-poor products, but no studies have compared the online marketing techniques and nutritional quality of products promoted on food companies' international websites. For this descriptive study, we developed a qualitative codebook to catalogue the marketing themes used on 18 international corporate websites associated with the world's three largest fast food and beverage companies (i.e. Coca-Cola, McDonald's, Kentucky Fried Chicken). Nutritional quality of foods featured on those websites was evaluated based on quantitative Nutrient Profile Index scores and food category (e.g. fried, fresh). Beverages were sorted into categories based on added sugar content. We report descriptive statistics to compare the marketing techniques and nutritional quality of products featured on the company websites for the food and beverage company websites in two high-income countries (HICs), Germany and the United States, two upper-middle-income countries (UMICs), China and Mexico, and two lower-middle-income countries (LMICs), India and the Philippines. Of the 406 screenshots captured from company websites, 67·8% depicted a food or beverage product. HICs' websites promoted diet food or beverage products/healthier alternatives (e.g. baked chicken sandwich) significantly more often on their pages (25%), compared to LMICs (14·5%). Coca-Cola featured diet products significantly more frequently on HIC websites compared to LMIC websites. Charities were featured more often on webpages in LMICs (15·4%) compared to UMICs (2·6%) and HICs (2·3%). This study demonstrates that companies showcase healthier products in wealthier countries and advertise their philanthropic activities in lower income countries, which is concerning given the negative effect of nutrition transition (double burden of overnutrition and undernutrition) on burden of non-communicable diseases and obesity in lower income countries.

Background: Xishuangbanna of Yunnan Province, southwest of China belongs to a global biodiversity and cultural hotspot. Agrobiodiversity plays an essential role in local livelihoods and traditional culture in the region. However, preliminary studies suggest that diversity of crop plants and livestock species is declining. We hypothesized that agrobiodiversity and traditional means of preserving agrobiodiversity are threatened because of changes in government policy in favor of commercial plantations, land use change and changes in traditional agricultural practices. We investigated whether or not agrobiodiversity was declining, the specific causes, and signs of active biodiversity conservation practices in ethnic minority communities of Xishuangbanna which could form the basis for extensive in situ conservation programmes. Methods: A series of field studies to document trends in agrobiodiversity were conducted in different ethnic minority communities in Menghai County, Mengla County and Jinghong City of Xishuangbanna of Yunnan Province, southwest of China between July 2015 and February 2016. Data was obtained through the use of semi-structured questionnaires, field observation and participatory rural appraisal (PRA) tools. A total of 360 ethnic households provided information on current status, functions, characteristics, changes, and threatened factors of farming crop and livestock resources. Some measures for in situ conservation of agricultural biological resources were also researched using PRA methods. Results: Two hundred twenty-six crop varieties belonging to 31 families, 71 genera and 101 species were identified in Xishuangbanna, which included 83 vegetable crops, 77 food crops, 24 spice crops, 22 fruit crops, 13 cash crops, 6 oil crops, and 1 cloth crop, respectively. There were 15 livestock varieties, belonging to 6 major species: cattle, pigs, goats, chickens, ducks, and geese. Different crop and livestock resources had their own characteristics, functions and threatened factors. Since 2002, agroecosystem, crop diversity and livestock diversity have declined greatly over the Xishuangbanna region as a whole under implementation of the Sloping Land Conversion Program (SLCP). Swidden agriculture was completely eliminated under this program and gradually replaced by large land areas devoted to rubber, tea and banana plantations. Villager numbers engaging in farming production and population of crops and livestock were greatly decreased, particularly in terms of production of local traditional varieties. However, some in situ conservation measures such as seeds preservation, planting of traditional crops and raising livestock have played an important role in local agrobiodiversity conservation. Conclusion: Abundant agricultural resources and agrobiodiversity are critical to the local livelihood and maintenance of traditional culture in Xishuangbanna. However, agrobiodiversity and related traditional culture have been greatly impacted by implementation of the SLCP since 2002. Therefore, in future conservation of agrobiodiversity, incorporating some sustainable protection measures based in local communities such as convening seed exchange fairs, conserving traditional varieties in permanent plots, making a visual documentary of indigenous cultivation, and providing traditional agricultural products to tourists should be carefully considered and adopted.
