HEI Scores for Americans
The Center for Nutrition Policy and Promotion (CNPP) uses the Healthy Eating Index (HEI) to provide a data-driven understanding of diet quality in the United States over time. The HEI-2015 can be used to see how well the diets of Americans align with the 2015-2020 Dietary Guidelines for Americans.
We use nationally representative survey data called What We Eat in America (WWEIA). The WWEIA is the dietary intake interview component of the National Health and Nutrition Examination Survey (NHANES), in which Americans report the types and quantities of foods and beverages they consume in a 24-hour period. Nutritionists at CNPP calculated average HEI-2015 scores for the American population using this information.
An ideal overall HEI score of 100 suggests that the set of foods reported is in line with the Dietary Guidelines recommendations. The average HEI-2015 score for Americans is 59 out of 100. This score indicates that average diets of Americans do not align with the dietary recommendations. A comparison of HEI scores looking at various age categories showed that HEI-2015 scores varied by age group:
- Older Americans ages 65 and over have the highest diet quality.
- Children ages 6-17 have scores that are lower than the population average.
- For all Americans regardless of age, overall HEI scores are far from the maximum of 100 points.

A data table titled Average Healthy Eating Index-2015 Scores for Americans by Age Group, WWEIA/NHANES 2015-2016 (shown below) shows how the HEI-2015 total scores and component scores vary. The dietary data came from the WWEIA portion of the 2015-2016 NHANES.
More information about how the scores are calculated is provided on the How the HEI is Scored page.
