Nutrients to Know

The body's primary source of energy comes from carbohydrates. Complex carbohydrates are nutrition dynamos loaded with vitamins, minerals, and dietary fiber. Most young adults require 6-9 ounces per day. For more information,  use http://www.choosemyplate.gov/

Grains: rice, oatmeal, cold cereals, quinoa, and cornmeal
Whole grain breads: whole wheat, rye, pumpernickel breads, bagels, and muffins
Pasta: whole wheat pasta, couscous, macaroni and spaghetti  
Starchy vegetables: potatoes, sweet potatoes, corn, peas, and beans

A plant and whole grain based diet is the best way to obtain dietary fiber. Dietary fiber has been shown to help control digestion disorders such as constipation, and irritable bowel syndrome. Aim for fruit and vegetables twice a day with half of your complex carbohydrates coming from whole grain sources. Be sure to drink plenty of fluids when eating high fiber foods.

The best know of all the carotenoids, beta-carotene is a powerful antioxidant that may help protect the body against cancer. The body also converts beta-carotene into Vitamin A, which is essential for promoting good vision, and for maintaining healthy skin, mucous membranes, teeth, skeletal and soft tissues. Aim for fruits and vegetables that are dark green, yellow orange, or red in color.

A multivitamin and mineral supplement cannot replace the disease-fighting properties found in complex carbohydrates, fruits and vegetables or turn an unhealthy eating pattern into a healthy one. You still need to make wise food choices most of the time.

Getting all the health promoting nutrients we need from food is ideal - but not always possible. If you choose to take a vitamin and mineral supplement, keep these important points in mind.

Select a multivitamin and mineral supplement that contains about 100% of the Recommended Daily Allowance (RDA). Mega dosing is not necessary, and may be harmful.
Avoid taking individual vitamins and minerals, unless recommended by a health professional. Vitamins and minerals interact with each other in a delicate balance. Overloading on one or two individual vitamins or minerals can interfere with the body's ability to use other vitamins and minerals.
Take your multivitamin and mineral supplements with meals to increase absorption.
