A healthy diet is rich in easy-to-eat foods amino acids, omega-3 fatty acids and vitamin CBut exactly how these micronutrients affect cardiovascular health has long been controversial. Now a new meta-analysis published in the Journal of the American College of Cardiology provides some clarity.
The researchers systematically reviewed a total of 884 studies available at the time on micronutrient intake for dietary supplements and analyzed their data. They have identified several micronutrients that reduce cardiovascular risk, as well as others that provide no benefit or even have a negative effect. More than 883,000 patients participated in the combined studies.
“We have developed the first comprehensive evidence-based, integrative table that identifies and quantifies the potential effects of micronutrient supplementation on cardiometabolic outcomes,” he said. Simin Liu, MD, MS, MPH, ScD, professor of epidemiology and medicine at Brown University. and the study’s principal investigator. “Our study highlights the importance of micronutrient diversity and balancing health risks and risks.”
The clinical findings could be used as a basis in future trials to study specific combinations of micronutrients and to say their impact on cardiovascular health.
Easy
Easy supply has long been thought to play a role in the heart health. Therefore, these nutrients work to reduce oxidative stress, a known contributor to many cardiovascular diseases. Heart-healthy diets, such as the Mediterranean diet and the Dietary Approaches to Hypertension (DISH), include foods that are naturally occurring. the rich in the easy things. However, it is not inconsistent with studies of antioxidant supplements, a single-system approach not yet widely adopted in preventive cardiology.
“Research on micronutrient supplementation has focused mainly on the health effects of one or a few vitamins and minerals,” said Liu. “We decided to take a comprehensive and systematic approach to evaluate all publicly available and available studies on all micronutrients, including phytochemicals and antioxidant supplements, and their effects on cardiovascular risk factors and multiple cardiovascular diseases.”
The researchers looked at the randomized controlled intervention trials that were evaluated 27 different antioxidant supplements. Strong evidence has been found to provide several cardiovascular benefits. These include:
They also showed evidence of reduced cardiovascular risk;
Not everything is convenient
Not all supplements were helpful. Vitamin C, vitamin D, vitamin E, and selenium showed no effect on long-term cardiovascular disease outcomes or type 2 diabetes risk. Beta carotene supplements all cause increased mortality.
According to the researchers, the findings point to the need for more personalized and precision-based cleaning interventions related to specific combinations of health supplements. More studies, including large, high-quality intervention trials, are needed to investigate the long-term effects of certain micronutrients on health.
“It is optimal to know the micronutrient mix, because not all of them are beneficial and even have harmful effects,” said Liu.
