Consumption of argan oil improves anti-oxidant and lipid status in hemodialysis patients

Abstract

Objective: Virgin Argan oil (VAO) is of interest in oxidative stress and lipid profile because of its fat composition and antioxidant compounds. We investigated the effect of VAO consumption on lipid profile and antioxidant status in hemodialysis patients after a 4-week period of consumption. Methods: In a crossover, controlled trial, 37 patients (18 men, 19 women) with end-stage renal disease on maintenance hemodialysis, were randomly assigned to a 4-week VAO diet. Fasting plasma lipids, vitamin E and oxidized LDL (ox-LDL) were analyzed. Malondialdehyde (MDA) was determined before and after hemodialysis session. Results: There was no significant change in serum total cholesterol and ox-LDL. However, VAO consumption decreased the levels of triglyceride (p-=-0.03), total cholesterol (p-=-0.02) and low-density lipoprotein (p-=-0.03) and increased the levels of high-density lipoprotein (p-=-0.01). Plasma vitamin E contents significantly increased from baseline only in VAO-group (p-
