title: Dietary modulators of lipid metabolism in the Indian diet-heart study (I.D.H.S.).
abstract: Of the 621 adults (25 to 65 years of age, 531 males) with either risk factors or with coronary heart disease (CHD) 310 subjects were given a cardiovasoprotective (CVP) diet (group A) and 311 subjects a normal diet (group B) in a randomized, single blind and controlled fashion. Risk factors and incidence of CHD were comparable between the two groups. The intervention group received a significantly higher percentage of calories in relation to complex carbohydrates, vegetable proteins, polyunsaturated fatty acids and high P:S ratio diet as compared to the control group. The control group received higher saturated fat and cholesterol. Compliance was assessed by dietary questionnaire during the follow-up. After 8 weeks of dietary trial, there was a significant decrease in mean serum total cholesterol (8.2 vs 2.1%), low density lipoprotein (LDL) cholesterol (9.8 vs. 2.7%) and triglyceride (11.2 vs 5.8%) in the intervention group compared to baseline levels and changes in control subjects. Body weight and physical activity at the entry to study and during the trial were similar in both groups. The decrease in mean HDL cholesterol were insignificant both in the intervention (4.3%) and control group (5.0%). There were no adverse effects of diet during the 8 weeks of trial. It is possible that a diet with 27.5% energy from total fat including 10.1% energy from monounsaturated fatty acids, P:S ratio 1.38, 120 mg dietary cholesterol, 26.0 g dietary fibre per 1000 kcal would modulate the lipid metabolism resulting in a significant reduction in serum total cholesterol, LDL cholesterol and triglyceride with no reduction in HDL cholesterol. This diet may be capable of reducing CHD incidence and mortality in the long term Indian diet-heart study (IDHS).
