What is HEI (Healthy Eating Index)?
Diet ID uses an objective measurement of diet quality known as the Healthy Eating Index (HEI) 2020. This method is the most robustly researched and validated tool for measuring diet quality in the US (it has been validated in other countries as well). Based on the Dietary Guidelines for Americans, HEI is particularly useful as it correlates strongly to disease risk and projected healthcare costs. Diet quality is stratified among all diet types and is represented visually as well as quantitatively. Visit this page for more about the HEI.
