Pumpkin seed oil (PSO) is high in unsaturated fatty acids and plant sterols, which have numerous cardiovascular benefits. The study explores the hypothesis by investigating effects of consumption of 1000 mg of PSO on total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), systolic (SBP) and diastolic (DBP) blood pressure ((BP). PSO has high oxidative stability and contains favorable essential fatty acids profile along with sterols and tocopherols. One hundred and

One hundred and twenty-seven participants 39 to 63 years old, with varying degree of one or multiple medical conditions including dyslipidemia, hypertension, diabetes and obesity were randomly selected and assigned among case and control groups. Both groups were biochemically, anthropometrically and clinically assessed pre and post intervention. Group 1 (cases) (n=63) was administered 1000 mg of PSO along with recommendations for healthy diet and lifestyle whereas Group 2 (controls) (n=64), was only provided with dietary and lifestyle changes. Analysis of cases baseline and endpoint data revealed advantageous effect of intervention. Cases data showed a significant reduction in endpoint LDL and DBP values along with a likewise significant increase in HDL cholesterol. Experiment results revealed PSO possessed hypolipidemic and anti-hypertensive activity as it lowered DBP and LDL and increased HDL levels. Keywords: pumpkin seed oil; low density lipoproteins; hypertension; blood pressure. Practical Application: 1000 mg of cold extracted Pumpkin seed oil can be used as adjuvant nutrition for balancing lipids and alleviating early onset of hypertension.
