The purpose of this research was to compare food-based recommendations and nutrient values of three food guides: the US Department of Agriculture's MyPyramid; the National Heart, Lung, and Blood Institute's Dietary Approaches to Stop Hypertension Eating Plan, and Harvard University's Healthy Eating Pyramid. Estimates of nutrient values associated with following each of the food guides at the 2,000-calorie level were made using a composite approach. This approach calculates population-weighted nutrient composites for each food group and subgroup, assuming average choices within food groups. Nutrient estimates were compared to the Dietary Reference Intakes and other goals and limits. Recommendations were similar regarding almost all food groups for both the type and amount of foods. Primary differences were seen in the types of vegetables and protein sources recommended and the amount of dairy products and total oil recommended. Overall nutrient values were also similar for most nutrients, except vitamin A, vitamin E, and calcium. These food guides were derived from different types of nutrition research, yet they share consistent messages: eat more fruits, vegetables, legumes, and whole grains; eat less added sugar and saturated fat; and emphasize plant oils.
美国农业部的“我的金字塔”；美国国家心肺血液研究所的“终止高血压膳食疗法饮食计划”，以及哈佛大学的“健康饮食金字塔”。采用综合方法对在2000卡路里水平遵循每种食物指南相关的营养价值进行了估算。该方法为每个食物组和亚组计算人群加权营养素组合，假设食物组内为平均选择。将营养素估算值与膳食参考摄入量以及其他目标和限值进行了比较。对于几乎所有食物组，在食物的类型和数量方面，建议都相似。主要差异体现在推荐的蔬菜和蛋白质来源类型以及推荐的乳制品和总油量方面。除了维生素A、维生素E和钙之外，大多数营养素的总体营养价值也相似。这些食物指南源自不同类型的营养研究，但它们传达了一致的信息：多吃水果、蔬菜、豆类和全谷物；少吃添加糖和饱和脂肪；并强调植物油。
