ABSTRACT

A total of 64 male obese subjects were randomized to observe the effect of 40 g of walnut in daily breakfast on lipid profile and Body Mass Index (BMI), total Cholesterol (CHO), Triglyceride (TG) High Density Lipoprotein (HDL) cholesterol and Low Density Lipoprotein (LDL) cholesterol in obese male subjects of various ethnics i.e. Baloch (B), Pathan (P), Hazara (H) and Punjabi (PU) residing in Quetta region of Balochistan for this purpose four weeks controlled study was designed. A batch of 32 obese male subjects 8 from each ethnic group as a control and another batch of 32 obese males 8 from each ethnic group as treated were selected. Twelve hour fasting blood samples a day after stoppage of walnut were taken from obese control and obese treated subjects. Daily walnut consumption in obese male subjects evidently demonstrated reduced BMI in all ethnic groups. Walnut supplementation in obese exhibited significant reduction in cholesterol level in Baloch (P < 0.001) and Punjabi (P < 0.01) males. There was profound and statistically significant [B (P < 0.05), P (P < 0.05), H (P < 0.01) and PU (P < 0.05)] elevation in HDL-C in all male ethnic groups. In male sub-population LDL-C was significantly [P (P < 0.01), H (P < 0.001) and PU (P < 0.05)] reduced in these groups. In these subjects walnut supplementation showed pronounced reduction [B (P < 0.001), P (P < 0.05), H (P < 0.001) and PU (P < 0.001)] in triglyceride levels. The constructive influence of walnut on lipid profile suggests that walnut rich diet may have advantageous effects beyond changes in plasma lipid level.
