NIH: What’s the Scoop? Common Misconceptions About Vitamins and Minerals
Misconception: Recommended dietary allowances (RDAs) refer to the amounts of vitamins and minerals you need from dietary supplements, such as multivitamins.
Fact: RDAs refer to the amounts of vitamins and minerals you need from all sources––food, beverages, and if you take them, dietary supplements. In most cases, whether you need a vitamin or mineral supplement depends on how much you get from the foods and beverages you consume each day. For example, the RDA for calcium is 1,000 milligrams per day for many adults. If you get that much from foods and beverages, you shouldn’t need a calcium supplement unless your health care provider recommends it. There are some exceptions for certain vitamins and minerals. For example, if you could become pregnant, you should get 400 micrograms a day of folic acid from dietary supplements and/or fortified foods in addition to what you get naturally from foods. This helps reduce the risk of serious birth defects, called neural tube defects. For more information about RDAs, see our vitamin and mineral fact sheets.
2025-2030 dietary guidelines will ‘meet personal & cultural preferences.’
BOSTON — In this video, Janet M. de Jesus, MS, RD, a nutrition advisor at the HHS’ Office of Disease Prevention and Health Promotion, provides an update on the development of the Dietary Guidelines for Americans, 2025-2030 edition.
de Jesus recently presented this update during a session at NUTRITION 2023. She said the guidelines provide “science-based advice on nutrition intake to meet nutrient needs, promote health and prevent chronic disease.”
“They are written for a professional audience, including health care providers, and they provide a customizable framework for healthy eating that can be tailored and adapted to meet personal and cultural preferences and budgetary considerations,” she said.
de Jesus also discussed how primary care physicians can incorporate the current edition of Dietary Guidelines for Americans into practice, which include recommendations for all stages of life.
“This includes all the way from birth and infants … pregnant and lactating people, all the way to older adulthood,” she said. “Therefore, health care professionals can find dietary guidance for all life stages, organized by chapters in the full dietary guidelines document.”
