Some individuals may have an addictive-like response to certain foods, possibly contributing to problematic eating. Highly processed foods, with added fats and/or refined carbohydrates, are suggested to be most associated with addictive-like eating. The incentive sensitization theory suggests that wanting (e.g. craving) may drive compulsive drug use rather than liking (e.g. enjoyment), but it is unknown whether highly processed foods elicit similar wanting and liking patterns as drugs of abuse, or whether individual differences exist. The current study examines the association of highly processed foods with craving and liking, and whether these relationships differ by food addiction symptomology, cognitive restraint, or body mass index (BMI). Participants (n = 216) reported craving and liking for 35 foods and completed the Yale Food Addiction Scale (YFAS) and Three Factor Eating Questionnaire (TFEQ). Highly processed foods were craved more overall. Craving of highly processed foods was predicted negatively by restraint and positively by YFAS score. Liking of highly processed foods was predicted negatively by restraint and positively by BMI. In conclusion, craving and liking appear distinct with respect to highly processed foods, and may be influenced by addictive-like eating, cognitive restraint, and BMI. This suggests that the incentive sensitization framework may also be relevant for problematic food consumption, especially for individuals reporting food addiction symptoms.
一些人可能会对某些食物产生类似成瘾的反应,这可能导致饮食问题。高脂肪和/或精制碳水化合物的高加工食品被认为与类似成瘾的饮食最为相关。动机敏感化理论认为,渴望(如渴求)可能会导致强迫性药物使用,而不是喜好(如享受),但尚不清楚高加工食品是否会引发与滥用药物类似的渴望和喜好模式,或者是否存在个体差异。当前的研究考察了高加工食品与渴求及喜好之间的关联,以及这些关系是否因食物成瘾症状、认知抑制或体重指数(BMI)而有所不同。参与者(n = 216)报告了对35种食物的渴求及喜好,并完成了耶鲁食物成瘾量表(YFAS)和三因素饮食问卷(TFEQ)。总体而言,对高加工食品的渴求更多。对高加工食品的渴求受到抑制的负向预测,以及YFAS得分的正向预测。对高加工食品的喜好受到抑制的负向预测,以及BMI的正向预测。总之,对于高加工食品,渴求与喜好似乎是不同的,并且可能受到类似成瘾的饮食、认知抑制和BMI的影响。这表明动机敏感化框架可能也适用于有问题的食物消费,特别是对于报告有食物成瘾症状的个体。
