Long F, Ooi CS, Gui T, Ngah AH. Examining young Chinese consumers' engagement in restaurant food waste mitigation from the perspective of cultural values and information publicity. Appetite 2022; 175:106021. [PMID: 35395361 DOI: 10.1016/j.appet.2022.106021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 03/14/2022] [Accepted: 03/25/2022] [Indexed: 11/02/2022]
Abstract
Food waste is a serious problem with regard to social equity and environmental challenges across the world. In recent decades, a dramatic growth of restaurant food waste has been seen in China. This study integrated the norm activation model (NAM), Chinese cultural values (i.e. face saving and group conformity) and information publicity to examine young Chinese consumers' food waste behaviors in a dining-out context. By drawing data from 311 respondents from Shenyang, Northeast China, this research finds that Chinese cultural values significantly influence personal norms and food waste practices. Meanwhile, publicized information could effectively shape cultural values and food waste behaviors. This study advances our understanding of young Chinese consumers' food waste behaviors from the perspective of cultural values and information publicity, which sheds light on how to mitigate the food waste challenge for policy makers, relevant NGOs, food service providers and even individuals.

Abstract
The rising popular belief that gluten is unhealthy has led to growth in gluten avoidance in people without coeliac disease. Little information is available on their dietary profiles and their dietary behaviours. Our aim was to compare the consumption of organic foods between gluten avoiders and non-avoiders, and their places of food purchase. We described their sociodemographic and dietary profiles. The study population included participants of the NutriNet-Santé cohort who completed both a food exclusion questionnaire and an organic semi-quantitative FFQ (n 23 468). Food intake and organic food consumption ratios were compared using multivariable adjusted ANCOVA models. Associations between gluten avoidance and organic food consumption as well as places of food purchase were investigated with multivariable logistic regression. Participants avoiding gluten were more likely to be women and had a healthier dietary profile. Organic food consumption was higher among gluten avoiders (48·50 % of total diet for total avoiders, 17·38 % for non-avoiders). After adjustments for confounders, organic food consumption and purchase in organic stores were positively associated with gluten avoidance: adjusted OR (aOR)Q5 v.Q1 organic food = 4·95; 95 % CI 3·70, 6·63 and aORorganic stores v.supermarkets = 1·82; 95 % CI 1·42, 2·33 for total avoiders. Our study highlights that individuals avoiding gluten are high organic consumers and frequently purchase their foods in organic stores which propose an extended offer of gluten-free food. Further research is needed to determine the underlying common motivations and the temporality of the dietary behaviours of healthy people avoiding gluten.

Abstract
BACKGROUND Little is known about celiac disease (CeD) diagnosis and management in China. AIM This pilot aimed to be the first study to describe, quantitatively and qualitatively, how individuals living in China navigate CeD and the gluten-free diet (GFD). METHODS Participants were 13 adults and four parents of children with reported CeD, recruited from 11 mainland China cities via an online GFD support group. CeD-specific quality of life (CD-QOL and CD-PQOL) and diet adherence (CDAT) were assessed. In-depth interviews addressed experiences with CeD and the GFD. RESULTS Six of 17 participants reported biopsy- or serology-confirmed CeD. The mean (SD) adult CDAT score was 15.2 (3.6), > 13 indicating inadequate GFD adherence. The mean adult CD-QOL score was 62.1 (24.1) out of 100, in the "medium" to "good" range. Results were similar in children. Major interview themes included: (1) a challenging journey to obtain diagnosis; (2) social and structural barriers to maintaining the GFD; and (3) reliance on self in management of CeD. CONCLUSION Obtaining a diagnosis, maintaining a GFD, and living with CeD can be extremely challenging in mainland China. Results suggest an urgent need for CeD-specific education and Asian-adapted GFD guidance for both healthcare practitioners and patients.

Appetite 2021; 163:105220. [PMID: 33785430 DOI: 10.1016/j.appet.2021.105220] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 02/26/2021] [Accepted: 03/14/2021] [Indexed: 12/11/2022]
Abstract
This study aimed to identify individual, household and sociodemographic factors associated with changes in food consumption that lead to changes in the diet quality, in the context of the COVID-19 pandemic concerning Brazilian adults. Improvements or worsening in diet quality (IDQ or WDQ) were verified using an exploratory online survey which investigated whether participants (n = 4780) increased or decreased their consumption of food subgroups that mark positive or negative food patterns. Respondents also agreed or disagreed with their beliefs about food safety, cooking skills, family support, home characterization, feelings and behaviors. All factors of influence on the IDQ or WDQ groups were always compared against the general participants (who did not change their diet sufficiently to be classified into these groups). Individuals from the IDQ group spent more time on food (81.4% versus 62.0%), started to cook more often (91.4%), were more confident with their cooking skills (p < 0.01) and positive feelings were at least 2.5 times more prevalent. Adjusted analysis showed the chance to improve diet was 1.39 higher among those who did not feel overworked and increased 1.07 in each additional cooking chore shared between household members. For each additional positive feeling, the odds were 1.41 to IDQ and 0.67 to WDQ. Moreover, for each additional negative feeling the chances for WDQ were 1.21 and 0.90 for IDQ. Those in the WDQ group were more unaware of issues related to contagion during meals, they were not afraid of eating food prepared outside their home and agreed that industrialized food is safer (OR = 1.85). These results highlight the associated factors in improving or worsening diet patterns as a consequence of the COVID-19 pandemic, supporting messages presented in Dietary Guidelines.

Abstract
Non-celiac gluten or wheat sensitivity (NCWS) is a "clinical entity induced by the ingestion of wheat leading to intestinal and/or extraintestinal symptoms that improve once the wheat-containing foodstuff is removed from the diet, and celiac disease and wheat allergy have been excluded". This mostly accepted definition raises several points that remain controversial on this condition. In the present review, the authors summarize the most recent advances in the clinic and research on NCWS through an accurate analysis of different studies. We screened PubMed, Medline, Embase, and Scopus using the keywords "non-celiac gluten sensitivity", "non-celiac wheat sensitivity", and "diagnosis". We would like to emphasize two main points, including (A) the controversial clinical and etiological aspects in different trials and experiences with particular attention to the Salerno criteria for the diagnosis of NCWS and (B) the histological aspects. The etiology of NCWS remains controversial, and the relationship with irritable bowel syndrome is obscure. Histologically, the duodenal mucosa may show a variable pattern from unremarkable to a slight increase in the number of T lymphocytes in the superficial epithelium of villi. The endorsement of this disease is based on a positive response to a gluten-free diet for a limited period, followed by the reappearance of symptoms after gluten challenge. The Salerno expert criteria may help to diagnose NCWS accurately. Social media and inaccurate interpretation of websites may jeopardize the diagnostic process if individuals self-label as gluten intolerant.

Abstract
Oats are increasingly popular among consumers and the food industry. While data exist on sensory characteristics of oats as such, previous studies focusing on the pleasantness of oats, and especially investigations of a wide range of oat products by European and Asian consumers, are scarce. An online questionnaire was organized in Finland (n = 381; 83.7% Finnish) focusing on the liking and familiarity of oat products, followed by sensory tests in Finland (n = 65 and n = 73) and China (n = 103) using the Check-All-That-Apply method and hedonic ratings. A questionnaire revealed that the Finnish consumers rated the pleasantness and familiarity of several oat product categories, such as breads and porridges, higher compared to participants of other ethnicities. Sensory tests showed both similarities, e.g., porridges were described as “natural”, “healthy” and “oat-like”, and differences between countries, e.g., sweet biscuits, were described as “crispy” and “hard” by Finnish consumers and “strange” and “musty” by Chinese consumers. Sweet products were unanimously preferred. The ethnicity had an important role affecting the rating of pleasantness and familiarity of oat product categories, whereas food neophobia and health interest status also had an influence. The proved healthiness of oats was a crucial factor affecting the choices of consumers and their acceptance in both countries.

Abstract
AbstractThe number of people avoiding gluten is growing in many Western countries. However, little information is available on their sociodemographic and dietary profiles. We aimed to describe sociodemographic, behavioural and dietary profiles of participants avoiding gluten in the NutriNet-Santé cohort. Participants of the NutriNet-Santé cohort – excluding coeliac patients – who completed a questionnaire about food exclusions, with complete data on sociodemographic characteristics and dietary intake were included (n 20 456). Food group consumptions and nutrient intakes according to self-reported avoidance of gluten were estimated using ANCOVA adjusted for age, sex and daily energy intake. Based on principal component analysis, three dietary patterns (DP) were identified. Association between DP and avoidance of gluten was investigated using multivariate logistic regression. All data were weighted on the French census. A total of 10·31 (95 % CI 9·90, 10·73) % of the participants declared avoiding gluten, of which 1·65 % totally. They were more likely to be women, older persons, non-smokers, to have a lower educational level and declared more food intolerances. They had higher consumption of fruit, vegetables and lower consumption of dairy products, salty/sweet and fatty foods and alcohol. After adjustments on confounders, a healthy dietary pattern was positively associated with total gluten avoidance (ORQuintile5vsQuintile1 = 14·44, 95 % CI 8·62, 24·19). Our study highlighted that, in this population, individuals who avoid gluten from their diet tend to have a diet more favourable to health. These results can serve as a basis for future studies investigating the potential consequences of a gluten-free diet in non-coeliac population.

Abstract
The importance of a gluten-free diet (GFD) in the treatment of celiac disease and other gluten-related disorders is undisputable. However, strict GFD often lead to nutritional imbalances and, therefore, to deficiencies. One of the most common deficiencies from a GFD are an insufficient amount of Ca, Fe, Mg, and Zn. This is mainly because the most of popular gluten-free (GF) raw materials are poor in minerals. Although the popularity of GFD is constantly growing, the data on minerals in GF products are still limited. More importantly, an access to the data is even more restricted. Therefore, the paper reviews the Ca, Fe, Mg, and Zn contents in hundreds of grain GF products available worldwide. The data for 444 products from categories of flours, mixes for cooking, bakery products, cereals, groats, rice, and pasta are obtained from research papers and nutritional databases. The calculation of the realization of mineral requirements from a portion of each product with its graphical classification as rich/average/poor source of each mineral is given. The review is a handbook of minerals for people on a GFD, dietitians, and food producers.

Abstract
Gluten-related disorders (GRD) affect millions of people worldwide and have been related to the composition and metabolism of the gut microbiota. These disorders present differently in each patient and the only treatment available is a strict life-long gluten-free diet (GFD). Several studies have investigated the effect of a GFD on the gut microbiota of patients afflicted with GRD as well as healthy people. The purpose of this review is to persuade the biomedical community to think that, while useful, the results from the effect of GFD on health and the gut microbiota cannot be extrapolated from one population to others. This argument is primarily based on the highly individualized pattern of gut microbial composition and metabolic activity in each person, the variability of the gut microbiota over time and the plethora of factors associated with this variation. In addition, there is wide variation in the composition, economic viability, and possible deleterious effects to health among different GFD, both within and among countries. Overall, this paper encourages the conception of more collaborative efforts to study local populations in an effort to reach biologically and medically useful conclusions that truly contribute to improve health in patients afflicted with GRD.
