Omega-3 fatty acids, folic acid, and CoQ10 reduce the risk of cardiovascular disease.

Some nutritional components benefit cardiovascular health, but others have no effect on cardiovascular health or may even harm it, according to a recent study. Nutritional components providing the greatest benefit include omega-3 fatty acids, folic acid, and coenzyme Q10 (CoQ10), a vitamin-like compound produced in the body.

Researchers analyzed the findings of more than 880 trials involving more than 880,000 participants that investigated the benefits of various macronutrients, micronutrients, and bioactive compounds on cardiovascular health.

They found that the nutritional components had varied effects on cardiovascular health. For example, while omega-3 fatty acids, folic acid, and CoQ10 reduced the risk of cardiovascular disease, selenium and vitamins C, D, and E had no effect on the risk for either cardiovascular disease or type 2 diabetes (which often coincides with cardiovascular disease). On the other hand, beta-carotene (a vitamin A precursor) increased the risk of death from all causes. The researchers did not investigate the effects of the various nutritional components in combination versus alone.

This analysis demonstrates that nutrition plays important roles in maintaining cardiovascular and metabolic health and supports the findings of large, epidemiological studies that have demonstrated that adherence to dietary patterns that are rich in omega-3 fatty acids, folic acid, and CoQ10, such as the Mediterranean Diet, for example, improves cardiometabolic health.
