Effect of walnut (Juglans Regia) consumption on hyperlipidemic adults

Abstract Present study was aimed to assess effect of walnut kernel with different dose on individuals with hyperlipidemia. Study was conducted at Fatima Memorial Hospital (FMH), Shadman, Lahore, Pakistan and 90 hyperlipidemic individuals were divided into 3 groups having no other disease. Total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were estimated in all three groups on 0 day (at start) 30th day and on 56th day of study. A significant (p < 0.05) result was observed and blood lipid profile of individuals were seen to improve by consuming walnuts. Group B who were fed 25 g walnuts kernel per day for 56 days a decrease of 21.6% in serum TC, 28.9% in serum TG, 26.5% in LDL-C; and an increase of 27.1% in HDL-C was observed as compared to control group. Whereas group C individuals who were fed 50 g walnut kernel per day showed a decrease of 30.3% in serum TC, 37.2% in serum TG, 33.8% in LDL-C and an increase of 50.0% in HDL-C was observed. It was concluded that consumption (25 g and 50 g) of walnut kernel showed significant (p < 0.05) improvements in lipid profile of hyperlipidemic individuals when consumed for 56 days.
