The new study says most nutritional supplements are ineffective

A new study in the United States shows that almost all vitamins, minerals and other nutritional supplements have no health benefits, but are also harmless to humans; only low-salt diets, omega-3 fatty acids and folic acid supplements are good for the health of some populations.
researchers at Johns Hopkins Medical Center in the United States collected data from nearly 1 million subjects worldwide and conducted 277 clinical trials to assess the correlation between 16 nutritional supplements such as vitamins and minerals and death and cardiovascular disease. The researchers also analyzed the health effects of eight diets, including a low-fat diet, a low-salt diet, and a Mediterranean diet that is rich in fruits and vegetables, fish, grains, and nuts.
found that most nutritional supplements, including multivitamins, selenium, vitamin A, vitamin B6, vitamin C, vitamin E, vitamin D, pure calcium and iron, do not have the health effect of preventing heart disease or prolonging life, but are harmless to the human body. Only low-salt diets, omega-3 fatty acids (fish oil) and folic acid supplements are good for the health of some populations, while calcium-vitamin D supplements may slightly increase the risk of stroke.
the findings have been published in the new issue of the American Anthology of Internal Medicine.
It's true that dietary supplements are not a panacea, despite the ongoing exploration," said study senior author Erin Mianjos. (Source: Xinhua News Agency, Peng Xi)
