Since 2009, the overall diet quality among Americans based on the healthy eating index score has stayed relatively the same.
The Healthy Eating Index (HEI) is a scoring measure that may be employed to assess both the general quality of a diet as well as the quality of various dietary components.
The U.S. Dietary Guidelines for Americans can be followed when using the HEI, which is a measure of diet quality independent of quantity (DGAs).
