This discrepancy may be related to the studied samples, which were partially in treatment, but also to the fact that previous studies tested for an approach bias under low cognitive load. Therefore, the present study assessed the food-specific approach behavior in an untreated sample with BED under high and low cognitive load, in comparison to a weight-matched and a normal weight control group. To this end, 50 individuals with BED, 20 individuals with overweight and 21 individuals with normal weight completed an approach avoidance task. In each trial, participants were instructed to either push or pull a slider device, dependent on the orientation of an arrow, which was superimposed on a picture. The underlying picture either depicted a high calorie food item or a neutral stimulus. Cognitive load was manipulated by two flanking arrows that either pointed in the same or the opposite direction to the task-relevant central arrow. First, and contrary to our hypothesis, the food-specific approach bias was not stronger in the group with BED compared to both control groups. Post-hoc tests further revealed no food-specific approach bias in any of the three groups. Moreover, and contrary to our hypothesis, cognitive load did not show a group specific impact on the food approach behavior. However, cognitive load did increase the food approach behavior across groups. The results of this study, in conjunction with previous studies suggest, that there is no clear food approach bias in individuals with BED, at least when movement direction is not explicitly contingent on picture content.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"219 ","pages":"Article 108434"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145800133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Italy is a nation characterised by a traditional culture of food that serves as a significant catalyst for collective identification and national pride. However, the country is experiencing significant changes that are precipitating a diversification of dietary habits and a transformation of the cultural identity of its citizens. A structured interview was administered to 156 participants (85 women) aged 19 to 68. A framework analysis of the interview data yielded three overarching themes: 'Veganism as a deficit', 'Veganism as naturalness', and 'Veganism as a threat'. The analysis demonstrated the pervasive negative perceptions of the vegan diet as a deficiency and a potential threat to cultural identity, alongside a concomitant stigmatisation of individuals who adhere to a vegan diet. This stigmatisation is rooted in the normative perspective of carnism, even in a country whose diet is not meat-centric. Notwithstanding this predominantly negative perception, one of the themes presented in this study offers a positive assessment of veganism, centred on its naturalness. The present analysis illuminates and deepens the multifaceted and somewhat contradictory nature of the social perception of veganism within a context characterised by contrasting features and relevant social changes.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"219 ","pages":"Article 108411"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145699506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores how hypoxia - whether environmental, as experienced at high altitude, or constitutive, as observed in older adults - affects taste function, with implications for nutrition under both extreme and age-related conditions. The research was structured in two parts: i. an investigation of taste perception during a high-altitude. Himalayan expedition, and ii. a cross-sectional comparison of taste sensitivity across age groups. In the first part, 17 healthy adults underwent taste tests at low altitude (Kathmandu, 1450 m), high altitude (Pyramid Lab, 5050 m), and again at low altitude after descent. In the second part, 103 participants were grouped by age (18–40, 41–64, and over 64 years) to assess age-related differences in taste function. Preliminary findings suggest that high-altitude exposure may moderately reduce taste sensitivity, particularly for sweet stimuli, requiring higher concentrations for correct identification. Similarly, ageing appears to impair taste perception, though the effect is not uniform across all taste qualities-salty taste, for instance, remains relatively preserved. These results point to a possible shared mechanism: the role of hypoxia in modulating sensory function. While the hypoxia encountered at high altitude is acute and environmental, older adults may experience a form of chronic, low-grade hypoxia due to physiological ageing. This parallel invite a broader reflection on how the body adapts to oxygen-limited conditions, and how such adaptations might inform nutritional strategies in both extreme environments and geriatric care.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"219 ","pages":"Article 108414"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145719990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify whether outlet healthiness rating tools and food menu characteristics can explain variance in energy consumed during OOH food eating occasions. Customers (N = 3718) were asked to recall their food orders upon exiting a range of OOH outlets across four local authorities in England during 2021 and 2022.

Random forest models and robust linear regression models clustered by outlet were used to identify whether outlet healthiness scores and individual menu characteristics were associated with kcal consumed. Energy consumed during OOH outlet visits was negatively associated with universal health rating scores (−28.3; 95 % CI -44.8 to −11.8; p = .003) but not associated with deep learning scores. Menu characteristics with the greatest importance and therefore contributing the most to predictive accuracy for energy consumed were the percent of savoury main menu items over 600 kcal and 1345 kcal, the number of desserts, the number of unique vegetables, and the percent of drinks over 100 kcal.

Second, there is a tendency to operationalize the term in ways that lead to large internal variations.

Third, there has been limited scientific discussion about the issues pertaining to the term ‘flexitarian’, which means that it is still unclear whether ‘flexitarians’ can usefully be viewed as a distinct consumer group.

General and generalized linear models evaluated associations between food insecurity (predictor variable) and disordered eating (outcome variables), adjusted for race, ethnicity, gender, age, education, and employment status.

Exploratory gender-stratified models suggested that the relationship between food insecurity and disordered eating behaviors, such as purging and night eating, may be stronger in veteran men than women. U.S. veterans with food insecurity demonstrate greater disordered eating, particularly night eating and purging behaviors, than those with food security. Gender differences suggest that disordered eating may function differently in men and women with food insecurity.
