The diets of most Americans fall short of the Dietary Guidelines for Americans. This exploratory analysis examines dietary patterns of low-income individuals classified as healthy and less healthy eaters based on their score on the Healthy Eating Index (HEI)-2005. The HEI-2005 is a 100-point score that measures how well populations adhere to the Dietary Guidelines for Americans. 

In 2006, FNS asked the Institute of Medicine to review the WIC food packages.

The IOM recommended that FNS conduct an impact study evaluating the birth month breastfeeding changes to the WIC food packages.
