College campuses provide an expansive food environment, which may contribute to elevated risk of excess energy intake and weight gain among college students. All-you-can-eat style cafeterias often expose students to hyper-palatable foods (HPF), which may promote overeating. This study aimed to examine the availability of HPF in an all-you-can-eat college cafeteria, and to examine HPF intake during meals among undergraduates.
Publicly available cafeteria menu data from a Midwestern university were analyzed and included 25 meals. To determine the availability of HPF within the cafeteria meals, the standardized definition of HPF by Fazzino et al. (2019) was used, which specifies combinations of palatability-inducing nutrients at quantitative thresholds that may induce hyper-palatability. Participants (N = 225) who ate in the cafeteria in the past 24 h were presented with a list of all menu items for their corresponding cafeteria meal, and self-reported all items consumed.
On average, 40 % (SD = 1.4) of total food items available per meal were HPF, with 68 % (SD = 3.6) of items with elevated fat and sodium. Regarding intake of HPF among students, approximately 64 % (SD = 31.4) of foods consumed were HPF, and 51 % (SD = 32.3) of items consumed had elevated fat and sodium.
Findings indicated that college students may be regularly exposed to HPF in all-you-can-eat college cafeteria environments, and that students may consume cafeteria meals that are primarily comprised of HPF.
大学校园提供了广阔的食物环境，这可能导致大学生摄入过多的能量和体重增加的风险增加。自助餐式食堂通常会让学生接触到高能量食物（HPF），这可能会导致暴饮暴食。本研究旨在检查自助式大学食堂中 HPF 的供应情况，并研究大学生在用餐时对 HPF 的摄入情况。
分析了一所中西部大学公开的食堂菜单数据，共包括 25 份餐食。为了确定食堂餐食中 HPF 的供应情况，使用了 Fazzino 等人（2019 年）标准化的 HPF 定义，该定义规定了在定量阈值下可能引起高味觉的诱食营养素的组合。在过去 24 小时内在食堂用餐的参与者（N=225），他们会收到一份对应食堂餐的所有菜单项目清单，并自行报告所有食用的项目。
平均而言，每顿饭提供的总食物中，HPF 占 40%（SD=1.4），其中 68%（SD=3.6）的食物脂肪和钠含量较高。关于学生对 HPF 的摄入情况，约 64%（SD=31.4）的食物是 HPF，51%（SD=32.3）的食物脂肪和钠含量较高。
研究结果表明，大学生可能经常在自助式大学食堂环境中接触到 HPF，并且学生可能会选择主要由 HPF 组成的食堂餐。
