Background: It is a common observation among doctors working in SKIMS Hospital, Srinagar (the main hospital in the valley) that the incidence of IHD is steadily increasing for the last 10-30 years. This increase is not only due to proper diagnosis but also paid to rapid change in socio-economic status, change in dietary habits, and high spread prevalence of hypertension. Though the staple diet of Kashmir’s is rice, they include meat almost every day in their diet. This study is an attempt to find the effect of non-vegetarian diet on serum cholesterol and blood pressure. The present study was done to assess the influence of non-vegetarian diet on serum cholesterol and blood pressure of general population in district Ganderbal. Objective: To determine dietary habits and dietary intake of fats and oils of sample, to determine the total serum cholesterol and blood pressure in non-vegetarian and vegetarians and to observe the effect of serum cholesterol on vegetarian diets. Design: The study was done on 100 adults among general population living in district Ganderbal. The sample was assessed clinically as well as interviewed to obtain required data regarding physical activity, dietary intake and their general information. Out of 100 50 were vegetarian and 50 were non-vegetarian. Results and Discussion: Results of the study clearly shown that mean serum cholesterol was significantly higher in non-vegetarians (238.4mg %) than in vegetarians (198.8mg %) while mean serum HDL-cholesterol of non-vegetarians (31.6mg %) was low as compared to vegetarians (34.4mg %). Mean serum cholesterol increased with increase in age and was high in sedentary workers (232.0mg %) with lowering of HDLcholesterol (30.6mg %) and was highest in subjects using ghee (270.9mg %). Mean systolic diastolic pressure was almost normal but increased with advancing with advancing age and sedentary life style. Conclusion: The data collected from the study indicated that all though the low iron intake of non-vegetarian and vegetarians was similar, more the vegetarians had the feelings of tiredness and pale-conjunctiva. Serum cholesterol was significantly higher in non-vegetarians as compared to vegetarians with lowering of HDLcholesterol, due to inverse relationship. This trend was also seen in subjects consuming more of saturated fat and sedentary workers. Blood pressure was normal in both the groups and not significantly different.
