Addressing factors such as competencies, self-efficacy and social norms enables sustainable positive change in nutrition behaviour. This study assesses the feasibility, acceptability, and preliminary effectiveness of a lay-led FL intervention for Arabic and Hebrew-speaking women in community settings, utilizing a train-the-trainer model. Feasibility was assessed through recruitment, attrition, and attendance rate, while acceptability and satisfaction were evaluated using participant feedback-forms. Preliminary effectiveness was evaluated using pre-post surveys measuring changes in FL level and Mediterranean diet adherence using validated scales (the adapted Short Perceived Food Literacy Scale (adapted SPFL, scale range 22-62) and the Israeli Mediterranean diet adherence screener (I-MEDAS, scale range 1-17)), utilizing the generalized estimating equations model. Outcomes of Hebrew and Arabic-speaking participants were compared using chi-square tests. Twenty-six lay-leaders were trained and subsequently conducted FL workshops for over 260 participants within 6 months. The 8-session workshop curriculum addressed multiple FL domains and was culturally adapted for Hebrew and Arabic-speaking populations. The intervention demonstrated feasibility with 77% attendance rate and 15% attrition rate. High acceptability was indicated by participant satisfaction with workshop content, length, structure, and lay-facilitators. The intervention demonstrated preliminary effectiveness with a three-point increase in FL level, as measured by the SPFL, from 48.66(±6.45) to 51.70(±6.13) (p < 0.001) post intervention. This change was seen in both Arab and Hebrew-speaking participants. Although overall I-MEDAS did not change significantly, Arabic-speaking groups showed a significant 0.75-point increase, and 50% of participants reported making dietary changes. The study demonstrates that lay-led FL interventions in the community utilizing a train-the-trainer model were feasible, well-accepted, and potentially effective in improving FL levels among diverse communities of women.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"107885"},"PeriodicalIF":4.6,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143035486","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 provides a comprehensive review of the relationship between taste preferences and personality traits, focusing on the five basic tastes (sweet, bitter, sour, salty, and umami) and spiciness. Through a systematic review of the literature from the past 30 years, 24 of 2182 articles were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol. This review identifies stable associations between certain tastes and specific personality traits. For instance, a preference for sweetness is linked to neuroticism and agreeableness, whereas preferences for bitter and sour tastes are associated with antisocial personality traits, such as Machiavellianism. Spiciness preference is closely related to sensation-seeking, extraversion, and impulsivity. Additionally, this review explores the potential physiological and psychological mechanisms underlying these associations, including (1) the direct impact of personality factors, (2) the role of brain functions (e.g. the insula), (3) the embodied metaphor theory, and (4) the potential effects of eating behaviour on personality. Despite these findings, the reliability of existing research is limited by small sample sizes and inconsistent measurement tools. Future studies should expand the sample diversity, develop more standardised measurement instruments, and further investigate the long-term effects of taste preferences on personality traits. This review offers new insights into the complex relationship between taste and personality and provides insights for future research and practical applications in real life.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"107875"},"PeriodicalIF":4.6,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021355","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}

Integrated nudging strategies are effective in promoting healthy eating behaviours. Therefore, this study aimed to investigate the effect of an integrated nudging intervention to promote plant-based meals and determine its effect on promoting sustainable food consumption behaviour. The effects of two versions of a meal on the frequency of choosing a plant-based meal were tested through a quasi-experimental pre-post intervention at three educational context canteens. During the intervention, the priming tools were strategically positioned between the meat meal and the plant-based target meal. In total, 3870 purchases were analysed to observe their choices. Additionally, a total of 508 consumers completed a pre- or post-intervention survey. Approximately 60.5 kg (133.4 lbs) less of food waste was generated during the intervention compared to the baseline with a reduction of 6.5 % per plate. The purchase of plant-based meals increased by about 38% from pre-to during-intervention, while meat-based meals decreased by about 19%. The grams of meal consumed per meat-based plate differed significantly from pre-to post-intervention, while that of plant-based did not differ significantly. The environmental assessment reveals that adopting a more plant-based diet and minimizing food waste for each plate significantly reduces the overall environmental impact of the meal. The integrated nudging strategy indirectly influenced sustainable food consumption behaviour through its effect on attitudes and subjective knowledge. Price-health-conscious consumers exhibited higher sustainable food consumption behaviour. These findings suggest that integrated nudging interventions can effectively shift consumer choices towards sustainable food options by influencing their attitudes and knowledge, eventually benefiting environmental sustainability and public health.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"107874"},"PeriodicalIF":4.6,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996736","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}

Interested participants completed questionnaires assessing habitual water intake, other health behaviours and several behavioural and psychological variables. Those who met the eligibility criteria for low daily water intake (N = 977) were invited to participate in a behaviour change challenge to increase water intake over 4 weeks (Phase 2). Additional online surveys were completed at baseline, week 2, and week 4 of the challenge with water intake assessed again at week 4. Participants were categorised into 7 groups based on expressed interest in participating, reasons for not wanting to participate, perceived current success with water intake, and their level of improvement during the challenge. Factor analysis of the behavioural and psychological variables identified four latent factors. We labelled these factors as Good Resources, Health Orientation, Driven Type, and Positive Energy.

We then wanted to determine whether the history of dieting was associated with higher reliance on external eating cues (such as emotional eating, uncontrolled eating, or ending a food intake because of the stomach overfullness or the plate emptiness) in individuals with obesity, and to examine whether these associations differed between subjects with different weight history. We included 1093 subjects with obesity from the GECCOS study and examined the association between external eating cues and dieting history (if < 3 diets or ≥ 3 diets) in the sample and in clusters (defined by hierarchical ascending classification on their weight history (based on current BMI, BMI at 20 years old and age of 1st diet)). Three clusters were obtained: a \"early-onset obesity\" group, a \"late-onset obesity\" group and an \"intermediate\" group.

This research examines how French consumers' responses to a FOP nutrition label-Nutri-Score-are influenced by their initial expectations regarding the overall healthiness of products. Based on expectancy-disconfirmation theory, we hypothesize that when products have a worse-than-expected Nutri-Score, the display of the FOP label will enhance guilt perception and reduce purchase intention. Conversely, when products have a better-than-expected score, the label display will diminish guilt perception and increase purchase intention. A pilot study, two controlled lab experiments, and one field study test our proposition. While in Studies 1 and 2 participants were randomly assigned to the label conditions (Nutri-Score vs. control), the prior expectations of healthiness were a non-randomized factor (Studies: Pilot, 1, and 2). Study 1 (N = 128) validates our proposition with judgments of an unhealthy food item (Nutri-Score-D). Study 2 (N = 147) extends these findings to both healthy and unhealthy food products. When the Nutri-Score grade was better-than-expected, it reduced guilt and boosted purchase intention, even for low nutritional quality foods (Nutri-Score-D). Conversely, a worse-than-expected Nutri-Score increased guilt and lowered purchase intention, even for healthier products (Nutri-Score-B).
