This report summarizes findings from the fourth School Nutrition Dietary Assessment Study, which collected data from nationally representative samples of school districts and schools in school year 2009-10. 

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.
