Abstract
Walnut (Juglans regia L.) is described as an anticancer, tonic, blood purifier, and detoxifier agent. It is said that nuts have favorable fatty acids and nutrients. This study was performed to determine the lipid-lowering properties of walnut in a population in Shiraz, Southern Iran. In a randomized case-control study, 52 volunteers were divided into 2 groups: Group A consumed walnuts, 20 grams per day for 8 weeks and the control group (group B) consumed no walnuts. Triglycerides, total high-density lipoprotein (HDL), and low-density lipoprotein (LDL) levels were checked for each subject prior to, after 4 weeks, and at 8 weeks after the beginning of the study. In group A, the mean plasma TG level dropped by 17.1% from the baseline and HDL cholesterol also increased significantly by 9%. It was shown that frequent consumption of nuts in the daily diet was associated with a potentially decreased risk of coronary artery disease by decreasing the level of triglyceride and increasing the level of HDL.
