Many people take vitamin supplements every day. But vitamin supplements are useless for most people except for certain groups who must consume them due to nutritional deficiencies or pregnancy, a report by a US government agency has found.

According to the latest report from the U.S. Special Committee on Disease Prevention (USPSTF), some studies suggest that multivitamins may slightly lower the risk of cancer, but broadly, there is enough evidence to conclude that vitamin supplements help prevent heart disease and cancer. there is no

The US Centers for Disease Control and Prevention is an independent governmental body.

However, there is ample evidence that beta-carotene supplementation may increase the risk of lung cancer and death from heart disease, especially in high-risk groups, according to the report. Additionally, vitamin E has not been shown to help prevent cancer or heart disease.

The US Centers for Disease Control and Prevention recently changed its stance on vitamins in 2014 like this.

“This is not a negative message, and I am not saying that vitamins and minerals do not have any cancer or heart disease prevention benefits,” said Dr. He is the director of the Medical Decision Program at Massachusetts General Hospital.

These new recommendations are based on a review of 84 studies published between January 2013 and February 2022. These studies looked at supplements, including multivitamins, and cardiovascular disease and cancer risk in healthy, non-pregnant adults.

The study found that people taking a multivitamin had a 7% lower risk of cancer than those taking a placebo (fake pill). However, this study had limitations, such as a short follow-up period.

The committee emphasized that the new recommendations do not apply to people with known or suspected nutritional deficiencies, pregnant women with special needs, or those who need to take folic acid because of possible pregnancy.

This recommendation was published in the online edition of the Journal of the American Medical Association and introduced by the American health media ‘Health Day’.

“Vitamin and mineral supplements are not a panacea for healthy people,” said Jenny Jia, a general internal medicine lecturer at Northwestern University Medical School, who wrote an editorial for the American Medical Association about the new study.

Instead of vitamins, she stresses that attention should be paid to a balanced diet rich in fruits and vegetables, regular exercise and screening tests that help prevent heart disease and cancer. “Vitamins and minerals are distracting and offer little or no benefit to healthy adults,” she said.

However, Dr. Mark Moyard (preventive and alternative medicine) at the University of Michigan Medical Center said, “A multivitamin taken daily can reduce cancer, and even a small reduction is by no means small.”

In particular, the US Council for Responsible Nutrition, representing the vitamin supplement industry, took issue with the new report.

“Americans are deficient in several key nutrients,” the committee said in a statement. It was also reminded that the Food and Drug Administration (FDA) and Dietary Guidelines for Americans 2020-2025 have identified insufficient intake of calcium, potassium, fiber and vitamin D as a public health problem in the United States.

Andrea Wong, vice chairman of the Committee on Responsible Nutrition, said, “Multivitamins can help slow cognitive decline in older people.”
