    Abstract:
    Fifty subjects with peripheral vascular disease were randomly assigned to either the American Heart Association Hyperlipidemia Diet C (AHA, N = 23) or a higher fiber, low fat diet based on the Pritikin maintenance diet (HFD, N = 27) and studied for a 12-month period. Diet counseling was provided, and the subjects were encouraged to exercise regularly, to decrease their consumption of salt, alcohol, and caffeine, and to restrict cigarettes as much as possible. Dietary intake data showed that energy distribution was approximately 49% and 64% carbohydrate, 20% and 22% protein, and 31% and 14% fat for the AHA and HFD groups, respectively. Cholesterol and dietary fiber intakes averaged 201 mg and 23 gm per day, respectively, for the AHA group and 108 mg and 43 gm per day, respectively, for the HFD group. Generally, both groups showed tendencies toward decreased serum triglycerides, cholesterol, and LDL cholesterol and increased HDL cholesterol. The HFD group achieved a significant decrease in serum cholesterol (at month 12) (p less than .01). The only significant between-group difference was in serum cholesterol at 4 months (p less than .01), with the lower value in the HFD group. There was a consistent negative correlation between dietary fiber and serum cholesterol levels (p less than .01). Average weight loss was 4.1 kg for the AHA group and 6 kg for the HFD group. We concluded that both dietary regimens, combined with exercise, can be of benefit to patients with peripheral vascular disease.
