The effect of highly purified sardine proteins was compared with that of casein on serum and lipoproteins lipid peroxidation and reverse cholesterol transport. Lecithin:cholesterol acyltransferase (LCAT) activity, high density lipoproteins (HDL2 and HDL3) composition and serum lipid and lipoproteins peroxidation were determined in rats fed a cholesterol-rich diet. Hypercholesterolemic rats were divided into two groups fed diets enriched with cholesterol and containing 20% of highly purified sardine proteins (SPc) or casein (CASc) for 28 days. A control group was fed a standard diet (CAS). Compared with CAS and CASc, the thiobarbituric acid reactive substances (TBARS) concentrations of low density lipoprotein (LDL)–HDL1 in SPc were 3.5- and 1.7-fold higher compared with casein diets. TBARS in HDL2 and HDL3 were, respectively, 2.3- and 1.6-fold lower in SPc compared with CASc. In SPc group, LCAT activity was higher compared to CASc and CAS (P < 0.05). Purified sardine proteins had no beneficial effects on LDL-cholesterol and lipid peroxidation. However, they reduced HDL oxidation and improved reverse cholesterol transport, in the hypercholesterolemic rat.
► We examine the effect of sardine protein on reverse cholesterol transport in the rat.
► Sardine protein has no beneficial effects on LDL cholesterol and lipid peroxidation.
► It reduces HDL oxidation in rats fed a cholesterol-rich diet.
► In the hypercholesterolemic rat, sardine protein enhances LCAT activity.
► We conclude that the sardine protein improves reverse cholesterol transport.
