Frequently Asked Questions

What is the Healthy Eating Index (HEI)?

HEI-2020 is a USDA-developed scoring system that measures how well a diet aligns with the Dietary Guidelines for Americans. It scores 13 components from 0-100, with higher scores indicating better diet quality.

What is a good diet score?

The average American scores about 58/100. Scores of 71-80 are "Good", 81+ is "Excellent" (top 5% globally). Mediterranean populations like Greece score ~72 on average. Japan and Okinawa score 73-78.

Does diet quality really affect life expectancy?

Yes. Research from Tufts (2023) shows each +10 point increase in HEI score is associated with approximately 1.5 additional years of life expectancy. A high-quality diet reduces all-cause mortality by up to 25%.

What is the Mediterranean diet?

A diet rich in vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, with moderate dairy and limited red meat. PREDIMED trials showed it reduces cardiovascular events by 30% and is one of the most evidence-backed diets for longevity.
