Dietary Supplements Provide No Health Benefits, Could Increase Death Risk

Nutritional Supplements Aren't Necessarily Nutritious Some vitamin supplements can increase risk of a stroke, study finds

"Except to prevent or specific deficiencies" similar to low vitamin D levels, or in specific circumstances similar to being pregnant, "there's usually a good agreement that dietary supplements shouldn't be recommended to the general population."The new analysis, which involved nearly one million sufferers overall, additionally discovered limited proof that a low-salt diet might reduce the danger of death, however, in an editorial following the review, specialists known as that a "peculiar and controversial finding". The remaining 13 supplements studied showed no benefit or harm.

Still, the authors conclude that there's enough evidence to suggest that people shouldn't start taking supplements just because they want to prevent heart problems.

"People should focus on healthy diet from nutritional food sources, not vitamins or supplements, in combination with healthy lifestyle which includes regular physical activity and not smoking", said Dr. Safi Khan, lead study author and a researcher at West Virginia University School of Medicine in Morgantown.

Dietary supplements provide no health benefits, could increase death risk.

"These tests are grossly overused, with limited utility in select patients", he said. Supplements that turned out with positive outcomes were omega-3 unsaturated fats and folic corrosive, which were found to secure against heart sicknesses and stroke. They looked at the effects of 16 nutritional supplements and eight dietary interventions on cardiovascular health and mortality.

Dietary supplements are popular among much of the urban populace of the world. They also noted that following a Mediterranean diet, reducing saturated fat intake, modifying fat intake, reducing dietary fat intake, and increasing the quantity of dietary omega-3 and omega-6 were not beneficial.

Not all supplements and diets are worthless, the review found. Folic acid supplements reduce the risk of a stroke, and omega-3 fatty acids were linked to reducing myocardial infraction (MI) and coronary heart disease. People with hypertension are already at risk for various cardiovascular events.

Satjit Bhusri, MD, a cardiologist with Lenox Hill Hospital in New York City, argues that "more powerful, diet specific trials" have demonstrated heart-protective gains from the Mediterranean diet. Reduced salt intake seems to lower blood pressure, according to a 2013 review, and "the science behind sodium reduction is clear", according to the American Heart Association. Vegetarian diets have also been tied to a lower risk of heart disease.

On the negative side, Khan and his colleagues note that their research found that calcium together with vitamin D might raise the risk for stroke.

The researchers hope that the study findings urge further investigation on the intake of nutritional supplements and the practice of certain dietary interventions, especially for those who are at risk for heart disease and stroke.
