Adherence to the Healthy Eating Index-2015 (HEI-2015) dietary pattern is associated with a significantly reduced risk of all-cause, cardiovascular disease, and cancer mortality in multiethnic adult populations.
To lower your risk of dying from heart disease, cancer, or other causes, aim for a diet that closely follows the 2015 Dietary Guidelines. This means eating more fruits, vegetables, whole grains, and lean proteins, while limiting refined grains, sodium, added sugars, and saturated fats. You do not need a perfect diet; simply moving from a low-quality diet to a higher-quality one (as measured by the HEI-2015) significantly reduces your mortality risk over the long term.
High HEI-2015 scores were inversely associated with risk of mortality from all-cause, CVD, and cancer for men and women (p-trend <0.0001 for all models).
Why this rating
Large prospective cohort (n > 215,000), long follow-up (17-22 years), multiethnic, adjusted for major confounders.
