Abstract

A high-fat diet is a major factor contributing to lipid metabolism disorders through increased synthesis and accumulation of cholesterol in the circulation. Hypercholesterolemia is closely associated with elevated oxidative stress, characterized by increased malondialdehyde (MDA) levels as a product of lipid peroxidation, thereby increasing the risk of cardiovascular disease. Omega-3–enriched eggs have been developed as functional foods containing omega-3 fatty acids with potential antioxidant properties that may reduce oxidative stress. This study aimed to determine the difference in blood malondialdehyde levels in high-fat diet–induced rats given omega-3 eggs compared to those given non–omega-3 eggs. This laboratory experimental study employed a post-test only with control group design using male Rattus norvegicus induced with a high-fat diet. The subjects were divided into a healthy control group, a high-fat diet control group, an omega-3 egg treatment group, and a non–omega-3 egg treatment group. After the intervention period, blood malondialdehyde levels were measured using the enzyme-linked immunosorbent assay (ELISA) method and analyzed using one-way ANOVA followed by Tukey’s HSD post hoc test. The results showed a difference (P < 0,05) between the omega-3 egg group and the non–omega-3 egg group, indicating that omega-3 eggs exert a protective effect by attenuating the increase in MDA levels compared to non–omega-3 eggs. Administration of omega-3 eggs resulted in lower malondialdehyde levels compared to non–omega-3 eggs, suggesting that omega-3 content plays a role in suppressing the increase in blood malondialdehyde levels.
