Dean Ornish Is Born
A doctor born in Dallas would spend his career proving that beans, oats, and a lot less fat could do what bypass surgery couldn't, until an insurer finally had to agree.

Dean Ornish was born on July 16, 1953, in Dallas, Texas. Trained as a physician, he spent the 1980s running small, rigorous trials asking a blunt question: could heart disease reverse itself if patients ate less fat, moved more, and dealt with their stress, without a single pill or scalpel? The data said yes, and his Program for Reversing Heart Disease combined a very low-fat, mostly plant-based diet with exercise, meditation, and support groups. In 1993 it became the first non-surgical, non-pharmaceutical therapy for heart disease to qualify for insurance reimbursement, and, chiropractic aside, the first alternative medical technique outside standard medical training to win approval from a major insurer. For a health system built on bypass surgery and cholesterol drugs, that was the moment a diet got treated like medicine.

With the exception of chiropractic care, it was the first alternative medical technique, not taught in traditional medical-school curricula, to gain approval by a major insurance carrier.

Why it still matters
Ornish gave plant-based eating something rare in medicine: a randomized trial and a paycheck. Once an insurer paid for the diet, doctors could prescribe it instead of just suggesting it.
