The Official Website of Dr. William Li - Bringing the latest discoveries of Food as Medicine into everyday practice to transform your health.

“Eating to beat disease empowers you to help yourself and the people you care about. You can love your food to love your health.”

– Dr. William Li, MD

I’m Dr. William Li. Years ago, when I first set out on my journey to study food as medicine, I realized what I was up against. The food industry did not care about health, and the health industry did not care about food. I am a medical scientist, and my mission is to bridge both of those worlds to help people everywhere become healthier while enjoying — and not being afraid of — their food.
