Pritikin vs AHA diet: No difference for peripheral vascular disease
1981
Korcok, Milan
An investigation of claims that the high-fiber, low-fat Pritikin diet has a beneficial effect on peripheral vascular disease was undertaken with 50 patients suffering claudication and atheroma. Each subject was assigned to either the Pritikin or the American Heart Association diet and was given intensive food preparation training; subjects were urged to exercise 45 minutes a day, and to restrict alcohol, coffee, and salt consumption and cigarette use. Vascular assessments were made at 2-month intervals for 1 year; actual nutrient intakes were assessed monthly. The Pritikin group consumed half the fat and cholesterol, 67% more fiber, 14% more carbohydrate, and the same amount of protein as the AHA group. Treadmill walking was improved in both groups. No significant differences were found for lipid changes, and no improvements were noted for blood flow in the limbs of either group. (cj)
