The Lifestyle Heart Trial

The Lifestyle Heart Trial was a randomized clinical trial conducted from 1986 to 1992 (1). People with moderate to severe coronary heart disease were randomized to an intensive lifestyle change group or to a usual-care control group. The intensive lifestyle changes diet included a 10% fat, whole foods vegetarian diet (mostly vegan), aerobic exercise, stress management training, smoking cessation, and support groups.

In the lifestyle changes group, the atherosclerosis in their arteries actually decreased 4.5% after one year and 7.9% after five years. In contrast, the atherosclerosis in the control group increased by 5.4% after one year and 27.7% after five years.

Total cholesterol levels in the lifestyle diet group went from 225 mg/dl to 188 mg/dl after five years, and they had a 74% reduction in frequency of angina. Twenty-five cardiac events occurred in 28 lifestyle change patients vs. 45 events in 20 control group patients.

This Lifestyle Heart Trial indicates that a whole foods vegetarian (and probably vegan) diet can be effective as part of a lifestyle change to reduce atherosclerosis and heart disease.
