Deep Nutrition: Why Your Genes Need Traditional Food

Medical school doesn’t teach doctors to address the root of the problem. It teaches doctors to treat the problem. It’s a practical science with practical aims.

Take, for instance, physics, which has built a body of deep knowledge by always digging down to get to the roots of a problem. Physicists have now dug so deep that they are grappling with one of the most fundamental questions of all: How did the universe begin? But medicine is different from other sciences because, more than being a science, it is first and foremost a business.
