美国（US）粮食系统主要是一项经济事业，具有深远的健康、环境和社会影响。评估食品系统的许多影响，包括食品系统提供健康饮食基本要素的总体质量和程度的一个关键数据来源是食品供应数据系统。本研究的目的是更新早期的研究，评估美国食品供应与最新的联邦饮食指南的一致程度，使用当前的健康饮食指数（HEI）-2010和2010年的食品供应数据。HEI-2010应用于40年的食品供应数据（1970-2010），以检查整体食品供应的趋势以及与健康饮食相关的特定成分，如水果和蔬菜。HEI-2010的总体综合评分在所有评估年份的最佳值的一半左右徘徊，从1970年的48分增加到2010年的55分（满分为100分）。大多数个别组成部分的分数波动并没有导致持续的趋势。目前的研究继续表明，联邦饮食指导和食品供应之间存在相当大的差距。在人口中与饮食有关的慢性病发病率很高的情况下，这种脱节是令人不安的，并表明需要不断监测食品供应的质量。迈向一个更有利于健康饮食的食品体系需要考虑一系列影响食品供求的因素。
The United States (U.S.) food system is primarily an economic enterprise, with far-reaching health, environmental, and social effects. A key data source for evaluating the many effects of the food system, including the overall quality and extent to which it provides the basic elements of a healthful diet, is the Food Availability Data System. The objective of the present study was to update earlier research that evaluated the extent to which the U.S. food supply aligns with the most recent Federal dietary guidance, using the current Healthy Eating Index (HEI)-2010 and food supply data extending through 2010. The HEI-2010 was applied to 40 years of food supply data (1970–2010) to examine trends in the overall food supply as well as specific components related to a healthy diet, such as fruits and vegetables. The HEI-2010 overall summary score hovered around half of optimal for all years evaluated, with an increase from 48 points in 1970 to 55 points (out of a possible 100 points) in 2010. Fluctuations in scores for most individual components did not lead to sustained trends. The present study continues to demonstrate sizable gaps between Federal dietary guidance and the food supply. This disconnect is troublesome within a context of high rates of diet-related chronic diseases among the population and suggests the need for continual monitoring of the quality of the food supply. Moving toward a food system that is more conducive to healthy eating requires consideration of a range of factors that influence food supply and demand.
