An egg a day doesn't risk your heart

Due to their cholesterol content, their reputation has been perceived as "bad" for quite some time, but now eggs are back in the game with a new study revealing that they don't increase the risk of heart attack.

The University of Eastern Finland study shows that a relatively high intake of dietary cholesterol or eating one egg every day is not associated with an elevated risk of incident coronary heart disease.

Furthermore, no association was found among those with the APOE4 phenotype, which affects cholesterol metabolism and is common among the Finnish population.

In the majority of population, dietary cholesterol affects serum cholesterol levels only a little, and few studies have linked the intake of dietary cholesterol to an elevated risk of cardiovascular diseases. Globally, many nutrition recommendations no longer set limitations to the intake of dietary cholesterol.

The study did not establish a link between dietary cholesterol or eating eggs with thickening of the common carotid artery walls, either.

The findings suggest that a high-cholesterol diet or frequent consumption of eggs do not increase the risk of cardiovascular diseases even in persons who are genetically predisposed to a greater effect of dietary cholesterol on serum cholesterol levels.

The findings are published in the American Journal of Clinical Nutrition.
