Fifty diabetic patients with mild hypertension were treated by a high fibre, low fat and low sodium diet or bendrofluazide for a three-month period. These two well-matched groups had a similar highly significant decrease in both systolic (P less than 0.001) and diastolic blood pressure (P less than 0.001). Both groups lost weight, the weight loss being greater in those receiving dietary therapy. Only dietary therapy was associated with a significant elevation of HDL2 level (P less than 0.05) and decrease in glycosylated haemoglobin (P less than 0.01). Bendrofluazide therapy resulted in significant elevation of glycosylated haemoglobin level (P less than 0.05) and at the end of the study this group had significantly higher glycosylated haemoglobin level (P less than 0.05) than the diet treated group. In those patients who were also hyperlipidaemic, 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 (P less than 0.01) while bendrofluazide treatment tended to elevate these levels. We conclude that a high fibre, low fat and low sodium dietary regimen lowers blood pressure, improves several other coronary risk factors and appears free of side-effects. This modified diet may be an attractive alternative to thiazide diuretic therapy in the mildly hypertensive diabetic subject.
