Frank Hu is a Chinese-American nutrition and diabetes researcher. He chairs the Department of Nutrition at the Harvard T.H. Chan School of Public Health and is a professor at Harvard Medical School.
He uses large, long-running cohorts such as the Nurses’ Health Study and the Health Professionals Follow-up Study to examine how diet and lifestyle relate to diabetes, cardiovascular disease and mortality.
A well-known analysis (Circulation, 2018) showed that Americans with five healthy habits — not smoking, healthy weight, enough exercise, moderate alcohol and a healthy diet — had a life expectancy at age 50 more than ten years longer.
He has published widely on red and processed meat, sugary drinks, whole grains and plant-based eating patterns.
He served on the advisory committee for the 2015 US Dietary Guidelines and wrote the textbook Obesity Epidemiology.
For longevity, his work shows how much can be gained from ordinary lifestyle choices that add up.
Takeaway: don’t chase one superfood; focus on an overall pattern of healthy habits you can keep for years.
