Effect of a high fibre, high carbohydrate dietary regimen on serum lipids and lipoproteins in type II hypertensive diabetic patients.
Fifty Type II diabetic patients with mild hypertension were treated by a high cereal fibre, low fat and low sodium diet in a controlled trial for a 3-month period. The modified diet and control diet groups were well matched although the control group had significantly increased levels of HDL2-cholesterol (p less than 0.05). The modified diet group had a significant reduction of mean serum triglyceride (p less than 0.05) and elevation of HDL2 (p less than 0.05) levels. There was also a reduction of systolic (p less than 0.001) and diastolic blood pressure (p less than 0.001), weight (p less than 0.01) and glycosylated haemoglobin (p less than 0.001). No changes were observed in the control group. In those patients with added hyperlipidaemia, dietary therapy resulted in a significant decrease of mean serum cholesterol (p less than 0.02), triglyceride (p less than 0.01) and glycosylated haemoglobin levels (p less than 0.01). The control group had a significant reduction of HDL-cholesterol (p less than 0.02). We conclude that a high cereal fibre, low fat and low sodium dietary regimen is associated with improvement in cardiovascular risk over a 3-month period, especially in those with hyperlipidaemia. Contrary to previous reports, no deleterious effect on serum triglyceride, HDL- and HDL2-cholesterol levels were recorded in this study. These data add further support to the recent dietary recommendations of several Diabetic Associations.
