The effects of consumption of walnut on serum lipids amount of normolipidemic and hyper lipidemic human

摘要

The objective of this study was accessing to the results of consumption of walnut with various amounts and during different consumption time on serum lipids amount. The number of researches on useful effects of walnut consumption on humans are few. Inthis study desirable and effective amounts of walnut and the results of its continued consumption are considered in both normolipidemic and hyperlipidemic groups. 130 persons randomly selected and after doing blood fatness tests they divided into two groups (60 persons with hyper lipidemic and 70 persons normo lipidemic statistical) and were tested by different amounts of walnut for one or two months.The average amount of total cholesterol, LDL-C,HDL-C/LDL-C, triglyceride and VLDL in all the patients were 219,134,215,39 mg percent before beginning of walnut consumption, that at the end of study after consuming walnut these figures were declined to 180(p<0.001), 107 (p<0.001), 3.12,173(p<0.005)and 30.9 (p<0.017) mg that showed significant decrease. The change of serum lipids spectrum remained in both group till one month after stopping walnut consumption and the average amount of cholesterol,LDL-C, LDL-C/HDL-C never reached to the amounts before beginning of walnut consumption walnut consumption have birary effect on hyper triglyceridimic.The present study results show that walnut consumption has useful effects on spectrum change of serum lipids. Its effect in hyperlipidemic persons and average consumption amount of 79 g daily is more desirable. Continuation of consumption again decreasesharmful lipid levels of blood and even its effect remains 1 month after stopping walnut consumption. The walnut diet was well tolerated, planned and observed diets were closely matched. Therefore, it is recommended that walnut can be used as lowering blood cholesterol in humans.
