The trial that reversed heart disease

In 1990 a young physician named Dean Ornish published a trial in a major medical journal that cardiologists found hard to believe. He took people with serious coronary artery disease and, instead of surgery or drugs, put them on a program: a very-low-fat plant-based diet, daily walking, an hour a day of stress management (yoga, breathing, meditation), and a weekly support group. A year later, their arteries, measured by angiogram, had opened. The control group's had narrowed. He called it the Lifestyle Heart Trial, and it was the first time anyone had shown heart disease going backward without a scalpel or a pill.

Later follow-ups held, and the program is now covered by Medicare as an alternative to surgery for some patients. What strikes me most, thirty-five years on, is which of the four parts mattered. People assumed it was the diet. Ornish's own analysis found that the patients who did best were the ones who attended the group. Connection moved the arteries.

I put it at the center of the Meaning chamber's table keys for that reason. The food matters. The walk matters. But Ornish's four-part program is a whole life, and the part that nobody expected, the weekly circle of people going through the same thing, was the part that healed. That's a Vault Human thesis in a cardiology journal.

The program is intensive and the diet is strict, ten percent of calories from fat, which most people can't sustain and don't need to. What everyone can take: all four pillars daily, and the group weekly. You've been doing three of them for a hundred and six days. The fourth begins when the circles do.
