New research from Columbia University Medical Center (CUMC) has shown that fish-oil rich diets can prevent the accumulation of fat in the aorta, even when total dietary fat intake remains high.

Their research showed that mice fed a high fat diet that was also high in fish oil accumulated much less fat in their aortas, the main artery leaving the heart, than controls not given the fish oil. They suggest that the fish oil markedly inhibited the entry of Low Density Lipoproteins (LDLs, ‘bad cholesterol’) into the arteries by decreasing the amount of lipoprotein lipase, a protein that traps LDLs in the arterial wall.

This is a new explanation of the mechanism by which omega-3 fatty acids (the fats found in fish oil) have a beneficial effect on heart health.

Fish oil, as you are no doubt well aware, is available practically everywhere in supplement form. Personally, I take 6g/day.
