本文测量了目前膳食指南和估计食物摄入量之间的食物消费差距。关于美国饮食对指南的遵守情况的信息来自两个来源：个人食物摄入量持续调查（CSFII）和美国农业部的年度食品供应数据（FSD）系列。我们回顾了以前的研究，并补充这些与我们自己的分析1994年CSFII和食品供应数据与食品指南金字塔服务的建议。这些分析表明，最大的相对差距出现在水果和奶制品类别以及添加糖;其他食物类别的差距较小。我们还考虑了未来的人口变化将如何影响这些差距的大小。如果目前的饮食模式在每个年龄、性别和种族类别中保持不变，那么我们预测未来大多数食物类别的总食物供应水平的差距将大幅增加。目前的摄入量与金字塔建议之间的差距之大表明，如果要缩小这一差距，就需要继续提高农业生产力，增加资源利用，并提高国际贸易水平。(C)1999爱思唯尔科技有限公司。保留所有权利。
This paper measures the current gap in food consumption between dietary guidelines and estimated food intakes. Information on the adherence of the US diet to the guidelines comes from two sources: the Continuing Survey of Food Intakes by Individuals (CSFII) and the USDA's annual Food Supply Data (FSD) Series. We review previous studies and supplement these with our own analysis of the 1994 CSFII and Food Supply data with Food Guide Pyramid serving recommendations. These analyses show that the greatest relative gaps occur in the fruit and dairy groups, and added sugars; smaller gaps exist for the other food groups. We also consider how future demographic changes will influence the size of these gaps. If current dietary patterns are maintained in each category of age, sex, and ethnicity, then we project substantial future increases in the gap at the aggregate food supply level for most food groups. The magnitude of the gap between current intakes and the Pyramid recommendations suggests the need for continued increases in agricultural productivity, higher resource use, and greater levels of international trade if the gap is to be closed.
