What are micronutrients?
Micronutrients are the vitamins and minerals found in food that nourish your body and help keep you healthy.
According to the U.S. Department of Agriculture (USDA), adult Americans do not typically get enough of the following nutrients:
- Vitamins A, C and E
Try to incorporate more of these nutrients in your daily diet. Keep in mind that it's best to consume a variety of foods, instead of just taking a multivitamin, to make sure that your body is able to absorb the micronutrients properly. If you are unable to get all the nutrients you need from food alone, ask your doctor if dietary supplements are right for you.
