Effects of walnut on serum lipids and lipoproteins in girls

Authors

Abstract

Opting an appropriate dietary regime has been and will be one of the simplest ways of providing health for and preventing disorders of human beings. Cardiovascular diseases-one of the most prevalent causes of morbidity and mortality worldwide-are in particular related to diet. Atherosclerosis, the most common pathogenic process of cardiovascular disease, is closely connected with food ingredients, specifically with the type of fat. Many experimental and clinical studies have shown the helpful effects of unsaturated vegetable oils, especially poly unsaturated fatty acids (PUFA) on serum lipids and lipoproteins. Walnut is a rich source of PUFA. The hypothesis in this research is that walnut ingestion could reduce the level of unfavorable serum lipids.
To determine the effect of walnut on serum lipids and lipoproteins, we carried the research out on 48 girl students having a mean age of 20.04, mean weight of 52.85 with no previously detected symptoms of any specific disease, they were divided into two groups; a case group of 25 and control group of 23. Before administering walnut, age, weight, serum lipids and diets of the population were thoroughly and analytically studied which illustrated no significant difference or variation. For 28 days, the case group ingested 40 grams of walnut a day along side with their regular diet, and at the same time, their serum levels of cholestrol, TG, LDL and HDL measured.
With the 28 days of walnut regime 40 grams daily the serum level of T.G and LDL was measured the result of which showed a statistically, significant drop (P<0.05) in the serum parameters, howere level of HDL showed an infenitesimal rise and the level of total cholestrol was of minimal fall, statistically insignificant.
The results earned supported the hypothesis that adding walnut into dietary regime could decrease harmful serum lipids.
