Abstract

Introduction: It has been established that omega 3 fatty acids have cardio-protective effects through modulation of cardiometabolic risk factors via multiple mechanisms. The aim of this study was to investigate the effects of flaxseed oil on anthropometric indices and lipid profile in patients with coronary artery disease (CAD). Methods: A randomized, double-blind, placebo-controlled trial was performed in 44 patients with CAD. The subjects were randomly assigned to receive either 200 ml of 1.5% fat milk supplemented by 5 g of flaxseed oil (containing 2.5 g α-Linolenic acid) as intervention or 200 ml of 1.5% fat milk as placebo group for 10 consecutive weeks. Anthropometric indices and lipid profile were assessed at baseline and post-intervention. Results: The results indicated that supplementation with flaxseed oil had no impact on anthropometric indices. Weight, body mass index, waist circumference and hip circumference decreased statistically significant within groups, but not between groups. At the end of the intervention, diastolic blood pressure (DBP) decreased significantly (P = 0.022) in the intervention group. Moreover, the triglyceride (TG) level decreased significantly in the intervention group from 173.45 (49.09) to 139.33 (34.26) (P < 0.001). Other lipid profile indices including total cholesterol, low density lipoprotein and high density lipoprotein did not differ significantly within and between groups. Conclusion: We observed that supplementation of flaxseed oil improved TG and DBP but had no effect on other lipid profiles and anthropometric indices in patients with CAD.
