Highly processed foods (e.g., pizza, chocolate) have been more associated with indicators of food addiction than have minimally processed foods (e.g., fruits, vegetables), although findings have been primarily self-reported. The present study utilized behavioral methods from the addiction literature to assess whether (a) foods differ in their associations with subjective experience indicators of abuse liability and (b) individual differences in subjective experiences and eating behavior emerge using the Yale Food Addiction Scale 2.0 (YFAS 2.0). Women (n = 44) with overweight or obesity, 38.6% with YFAS 2.0 food addiction, rated facets of subjective experience (e.g., craving) during a taste test task and ad libitum consumption period. A hierarchical linear model assessed whether foods were differentially associated with each subjective experience (Level 1) and individual differences by food addiction (Level 2). Associations between subjective experiences and eating behavior were also examined. Highly processed, relative to minimally processed, foods were more associated with indicators of abuse liability, although individuals with food addiction reported decreased enjoyment for and intentions to consume highly processed foods. Subjective experiences were associated with greater consumption of highly processed foods for participants with food addiction. The present work provides further support for the rewarding nature of highly processed foods, evidenced by closer associations with subjective experiences reported for drugs of abuse compared to minimally processed foods. In addition, highly processed food intake was related to elevated subjective experience reports for these foods for those with food addiction, paralleling findings in individuals with a substance-use disorder for the relevant drug.

高度加工食品(例如披萨、巧克力)与食物成瘾的指标更为相关,而最低限度加工食品(例如水果、蔬菜)则不然,尽管这些发现主要是自我报告的。本研究利用成瘾文献中的行为方法来评估(a)食物在与滥用倾向的主观体验指标的关联方面是否存在差异,以及(b)使用耶鲁食物成瘾量表 2.0(YFAS 2.0)是否会出现个体差异的主观体验和饮食行为。超重或肥胖的女性(n=44,38.6%患有 YFAS 2.0 食物成瘾)在味觉测试任务和随意进食期间对主观体验的各个方面(例如渴望)进行了评分。分层线性模型评估了食物是否与每个主观体验(第 1 级)以及食物成瘾(第 2 级)的个体差异存在差异。还检查了主观体验与饮食行为之间的关系。与最低限度加工食品相比,高度加工食品与滥用倾向的指标更为相关,尽管食物成瘾者报告对高度加工食品的享受度和摄入量减少。对于有食物成瘾的参与者,主观体验与高度加工食品的摄入量增加有关。本研究进一步支持了高度加工食品的奖赏性质,与药物滥用相比,高度加工食品与报告的主观体验更密切相关。此外,对于那些有食物成瘾的人来说,这些食物的主观体验报告与高度加工食品的摄入量有关,这与相关药物中物质使用障碍个体的发现相似。(PsycINFO 数据库记录(c)2019 APA,保留所有权利)。
