The authors assessed the accuracy of college students' use of the Food Guide Pyramid (FGP) in their diets and evaluated sources of error and nutritional adequacy of the pyramid. Students enrolled in an undergraduate nutrition class (N = 346) completed 3-day dietary records that were analyzed, using computer software, to determine individual recommended dietary allowance (RDA) values and the extent to which the students' diets met those values. The students' most common error in using the FGP was underestimating serving sizes. Only 8% of the students consumed the minimum recommended number of servings for all food groups, but diets that satisfied FGP recommendations also tended to satisfy RDA requirements. Less than 2% of the students who met the minimal number of FGP servings did not satisfy their RDA values, but less than 45% of the survey participants, regardless of gender or residence, met the recommended intake for dietary fiber. The FGP was judged to be a good indicator of dietary adequacy.
作者评估了大学生在饮食中使用食物指南金字塔（FGP）的准确性，并评估了该金字塔的误差来源和营养充足性。参加本科营养课程的学生（N = 346）完成了3天的饮食记录，这些记录使用计算机软件进行分析，以确定个人推荐膳食摄入量（RDA）值以及学生饮食满足这些值的程度。学生在使用FGP时最常见的错误是低估食用量。只有8%的学生摄入了所有食物组推荐的最低食用份数，但符合FGP建议的饮食也往往满足RDA要求。达到FGP最低食用份数的学生中，不到2%未满足其RDA值，但无论性别或居住地点如何，不到45%的调查参与者达到了膳食纤维的推荐摄入量。FGP被认为是饮食充足性的良好指标。
