背景建议在购买时贴上营养标签，以改善食物选择，但食物选择并不总是转化为食物消费。重要的是要了解标签使用，食物选择，服务和消费之间的关系。以往的研究，这依赖于自我报告的摄入量或推断标签使用或摄入量的基础上销售data.Objective没有充分回答这个问题，联合收割机调查和膳食摄影数据比较标签用户和nonusers.Design食客之间的食物选择，服务，和消费进行了调查，在2014年秋季学期的两个横截面波。食物的选择被记录下来，用餐前和用餐后的照片被拍摄下来。照片被编码，以确定选择，服务，和消费的MyPlate食品categorys.Participants/setting方便样本的1,069食客（39%的女性，53%的新生）在两所大学的霍尔斯。学生必须年满18岁，并且刚刚开始用餐才能参加。主要结果测量标签使用者和非使用者的MyPlate食物类别的选择，服务和消费。通过X2检验检验食物选择的差异，并通过t检验检验调整后的最小二乘均值的差异。结果选择营养标签使用者的比例更大，水果、蔬菜和豆类，与不使用者相比，选择的土豆更少。此外，更少的标签使用者选择油炸食品和添加糖的食品（所有P值
Background Nutrition labels at the point of purchase are recommended to improve food choice, yet food choice does not always translate into food consumption. It is important to understand the relationship between label use, food selection, servings, and consumption. Previous research, which has relied on self-reported intake or inferred label use or intake based on sales data, has not adequately answered this question.Objective To combine survey and meal photographic data to compare food selection, servings, and consumption between label users and nonusers.Design Diners were surveyed in two cross-sectional waves during the fall 2014 semester. Food selections were recorded, and pre-and postmeal photographs were taken of diners' plate. Photographs were coded to identify the selection, servings, and consumption of MyPlate food categories.Participants/setting Convenience sample of 1,069 diners (39% women, 53% freshman) in two university dining halls. Students had to be older than age 18 years and just beginning their meal to participate.Main outcome measures Selection, servings, and consumption of MyPlate food categories for label users and nonusers.Statistical analyses performed Differences in food selection were tested via X2 tests, and differences in adjusted least squares means for servings and consumption were tested via t tests.Results A greater proportion of nutrition label users selected fruits, vegetables, and beans and fewer selected potatoes compared with nonusers. In addition, fewer label users selected fried foods and foods with added sugars (all P values
