The purchase and consumption of multivitamin supplements and supplements to reduce the risk of diseases would be an unnecessary expense for healthy adults and women who are not pregnant, based on scientists and recommendations of the United States Preventive Services Task Force. Good nutrition and exercise would be the key.
In 2021, people in the US spent close to $50 billion on vitamins and dietary supplements. The most commonly cited reason they have for using supplements is for health, general wellness, and to fill in nutrient gaps in the diet.
Northwestern Medicine scientists say that for healthy Americans and non-pregnant women, vitamins are a waste of money because There is not enough evidence that they help prevent cardiovascular disease or cancer.
“[Los pacientes] they’re wasting money and focused on thinking there has to be a magic set of pills that will keep them healthy when we should all be following the evidence-based practices of eating healthy and exercising,” says Dr. Jeffrey Linder, professor of medicine at Northwestern University.
Linder and other scientists support the recommendations of the United States Preventive Services Task Force (USPSTF) published in JAMA.
“The USPSTF advises against the use of beta-carotene or vitamin E supplements for the prevention of cardiovascular disease or cancer…Current evidence is insufficient to assess the balance of benefits and harms of the use of multivitamin supplements, single or combined nutrients for disease prevention cardiovascular or cancer.
Some studies have associated vitamin D intake with a lower risk of cancer. However, the statement published in JAMA notes that studies must be of sufficient duration to detect an effect on this outcome.
The task force reviewed 84 studies that tested vitamins on nearly 700,000 people.including 52 new studies on the subject.
The new guidelines do not apply to pregnant people
The new USPSTF guidelines do not apply to people who are pregnant or trying to get pregnant, said Dr. Natalie Cameron, co-editorial author of JAMA.
Health experts recommend getting nutrients from food
The dietary guidelines for Americans, people should get most of their nutrients from food and drink.
Eating fruits and vegetables is associated with a long life and a decreased risk of cardiovascular disease and cancer. Scientists explain that whole fruits and vegetables contain a mix of vitamins, phytochemicals, fiber, and other nutrients that likely act synergistically to provide health benefits.
People who are deficient in vitamins can benefit from taking supplements
Dr. Jeffrey Linder professor of medicine at Northwestern University points out that dietary supplements, such as calcium and vitamin D, have been shown to prevent fractures and perhaps falls in older adults.
“Food contains vitamins, minerals, dietary fiber and other components that benefit health. In some cases, fortified foods and dietary supplements they are useful when it is not possible to meet the needs of one or more nutrients (for example, during specific stages of life, such as pregnancy”shares the NIH Office of Dietary Supplements.
