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.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
