Decrease in the Inflammatory Marker TNF-α after Consumption of Flaxseed by Hypercholesterolemic Rabbits

Abstract Background: Functional foods such as flaxseed have been commonly consumed to prevent atherosclerosis. Objectives: To assess the effects of flaxseed in atherogenesis in rabbits consuming a high-cholesterol diet. Methods: Thirty male albino rabbits were randomized to three groups based on a 12-week dietary treatment: control group (G1), standard diet; high-cholesterol diet (G2), standard diet plus 0.25% cholesterol from lyophilized eggs; and high-cholesterol plus flaxseed (G3), similar diet as G2 plus flaxseed. Biochemical (total cholesterol [TC], high-density lipoprotein [HDL-C], low-density lipoprotein cholesterol [LDL-C], and triglycerides) and immunohistochemical (intercellular adhesion molecule 1 [ICAM-1] and tumor necrosis factor alpha [TNF-α]) analyses were performed in all groups.
