They discover some micronutrients that can help you prevent heart disease

The antioxidants are nutrients widely known for their cardiovascular benefits.

Usually the healthy diets that are recommended as beneficial for the heartsuch as the Mediterranean diet and the dietary approach to stop hypertension, more commonly known as the DASH diet, already include foods that are naturally rich in antioxidants.

However, the world of antioxidant-based supplements it is much more unknown.

For years, researchers have believed that antioxidant-based supplements are essential for maintaining good heart health. In part, that may be true, as these nutrients are beneficial for oxidative stress, a known contributing factor in many cardiovascular diseases.

Despite this, existing studies they are inconsistent, that is why supplements with antioxidants are not yet used and recommended in preventive cardiology.

At this point, it is known that healthy diets are rich in antioxidants such as amino acids, omega-3 fatty acids, and vitamin C, but it is not entirely true that these micronutrients alone are good for health. cardiovascular.

With this, a group of experts has carried out a meta-analysis of more than 884 studies that has revealed that omega-3, folic acid and coenzyme Q10 (CoQ10) would be three of the micronutrients that do help reduce the risk of cardiovascular disease as published in the magazine Journal of the American College of Cardiology.

There are some micronutrients that would be beneficial for the heart

This group of researchers has reviewed a total of 884 available studies on micronutrients taken as dietary supplements. Through these analyses, identified several micronutrients that do reduce cardiovascular risk, but they also saw that there are others that offer no benefit or even some that have a negative effect.

As Simin Liu, professor of epidemiology and medicine at Brown University, in the United States, and principal investigator of the study, explains, for the first time “a comprehensive and integrative evidence-based map for characterize and quantify the potential effects of micronutrient supplementation on cardiometabolic outcomes.

On this point, the study has highlighted “the importance of micronutrient diversity and the balance of health benefits and risks.”

Thus, these findings could serve as the basis for future clinical trials to study specific combinations of micronutrients and their impact on cardiovascular health.

Were all the antioxidant supplements beneficial?

As Liu explains, they looked at different randomized controlled intervention trials evaluating 27 different types of antioxidant supplements and found strong evidence that several offered cardiovascular benefits.

Between the antioxidant supplements that offered benefits for the heart were the omega-3 fatty acid, which reduced mortality from cardiovascular diseases; folic acid, which decreased the risk of stroke; and coenzyme Q10, an antioxidant sometimes marketed as CoQ10, which reduced all-cause mortality.

In addition, omega-6 fatty acid, L-arginine, L-citrulline, vitamin D, magnesium, zinc, alpha-lipoic acid, melatonin, catechin, curcumin, flavanol, genistein, and quercetin were also some of the supplements that “showed evidence of reduced cardiovascular risk”.

However, “not all supplements were beneficial.” For example, vitamin C, vitamin D, vitamin E, and selenium did not show any effect on long-term cardiovascular disease outcomes or type 2 diabetes risk.

Likewise, some were harmful such as beta-carotene supplements, which increased all-cause mortality.

With these data, the researchers believe that “more personalized and precise dietary interventions that include specific combinations of beneficial supplements.”

Thus, further studies are neededsince the antioxidant micronutrients that are beneficial must be well identified, since some may even have harmful effects, the experts conclude.
