Across four online experiments, this research examines how GenAI communication style influences consumers' responses to alternative-protein recommendations. The findings suggest that, in a baseline recommendation context, unhedged communication is associated with greater willingness to choose alternative proteins through lower consumption discomfort. However, this effect depends on the recommendation framing. Under benefit-oriented framing, hedged communication is more effective when environmental value is emphasized, whereas unhedged communication is more effective when personal health value is emphasized. Under barrier-oriented framing, unhedged communication performs better when alternative proteins are assimilated into familiar food schemas, whereas hedged communication is more effective when consumers are invited to accommodate novel protein options. Using construal level theory as a theoretical lens, this research develops a fit account in which communication effectiveness depends on whether linguistic certainty fits the psychological task emphasized by the recommendation frame. The findings advance research on alternative protein acceptance and provide guidance for designing GenAI recommendations that encourage sustainable food choices.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"108827"},"PeriodicalIF":4.2,"publicationDate":"2026-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149369758","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}

For that, we conducted a think-aloud ranking task to examine 26 packaged foods under two experimental conditions (n_naturalness = 75, n_processing = 75) in the German-speaking part of Switzerland. Our results indicated a very high correlation between processing and naturalness perceptions, suggesting that these constructs overlap for laypeople. Furthermore, the participants used the same cues to assess both processing level and naturalness, consistently mentioning ingredient-related cues. Specifically, we observed strong correlations between the products' number of ingredients and their processing and naturalness assessments. For other cues, such as the number of food additives, much lower associations were observed. Hence, the use of the number of ingredients can be viewed as a heuristic that consumers use when evaluating food products. Reliance on this heuristic may not necessarily result in biased decisions, but it can lead to suboptimal choices from a sustainability and nutritional perspective.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"108810"},"PeriodicalIF":4.2,"publicationDate":"2026-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149284544","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}

Binge eating – a core feature of Binge Eating Disorder and Bulimia Nervosa – is frequently triggered by acute stress. One proposed mechanism is that stress increases the motivational salience of food cues, which could promote craving and food intake. To test this idea experimentally, this study examined how stress affects attentional bias toward food, and how such changes relate to food craving and food intake in individuals with binge eating behaviors compared with individuals without binge eating. Using a mixed experimental design, 130 participants (68 with binge eating, 62 without binge eating) completed sessions with and without stress induction via a video-conference Trier Social Stress Test. Attentional bias was assessed via the Dot Probe Paradigm and eye tracking, food craving was measured via self-reports, and food intake was measured behaviorally. Stress did not significantly change attentional bias toward food, nor did it affect food intake. Stress did increase craving in the group with binge eating, indicating that stress enhanced the motivational value of food. The absence of corresponding changes in attentional bias suggests that heightened craving under stress does not necessarily translate into measurable shifts in attentional allocation toward food cues, or that stress may influence motivational processes without altering overt attentional patterns. Another possibility is that methodological restraints specific to our study design limited the detection of stress-related changes in attentional processes. Further research is needed to clarify the role of attentional processes in stress-related eating, especially regarding binge eating.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"221 ","pages":"Article 108472"},"PeriodicalIF":3.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146043547","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}

The goal of the present study was to examine the role of emotion regulation in the relationship between ACEs and food addiction.

This pre-registered within-subject study investigated whether combining exposure with positive or negative reinforcement (using non-food rewards) enhances intake and liking of unfamiliar vegetables compared to exposure alone or a control condition. Sixty-two children aged 4–6 years participated in a 10-day school-based intervention involving all four conditions: positive reinforcement (tasting earned a cartoon card), negative reinforcement (tasting prevented card loss), exposure (tasting without rewards), and a control condition. Intake and liking of four unfamiliar vegetables (purple carrot, yellow beetroot, blue meat radish, and rutabaga) were measured on days 1 and 10, with intake also recorded during the intervention (days 2–9). Conditions and vegetable order were counterbalanced. The potential influences of reward sensitivity (RS) and punishment sensitivity (PS), and picky eating were also examined. Results from repeated-measures ANOVAs showed that positive reinforcement led to the highest post-intervention intake, followed by negative reinforcement, exposure, and control, with significant differences between all conditions. For liking, only positive reinforcement showed a significant improvement over the other conditions. RS and PS did not moderate outcomes, but higher picky eating was associated with lower intake and liking across all conditions. In conclusion, adding positive reinforcement to exposure most effectively increases young children's intake and liking of unfamiliar vegetables. This low-cost, easily implementable strategy can support parents and educators in promoting healthier eating habits in early childhood.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"221 ","pages":"Article 108469"},"PeriodicalIF":3.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146015740","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}
