Michael Greger is an American physician and New York Times bestselling author. He focuses on a whole foods plant-based diet to prevent and reverse major chronic diseases.

As a kid, he was inspired to get into medicine when his grandma reversed her advanced heart disease by switching to a plant-based diet. She went from being in a wheelchair on death’s door to walking 10 miles a day within three weeks of the switch.

"If [you are] over the age of 10, the question isn't whether or not to eat healthy to prevent heart disease, it's whether or not you want to reverse the heart disease you already have."

In 2011, he founded the nonprofit website NutritionFacts.org which was funded by the Jesse & Julie Rasch Foundation. On his site, he compiles information from the latest nutrition journals into articles and YouTube videos for free to the public.

In 2015, he released his book How Not To Die where he talks about how to eat your way to optimal health. He also recommends his daily dozen list of foods including beans, berries, greens, flax, turmeric, and many other nutrition packed foods.
