Document Summary
Vitamins are organic compounds essential in the diet to promote growth and health maintenance. Water-soluble vitamins include the b vitamins and vitamin c. B vitamins were originally thought to be one chemical substance but are actually many different substances. Added nutrients are generally not found in the food or are added in much larger amounts, such as fortifying orange juice with calcium. Enrichment: adding nutrients back to foods that habe lost nutrients dur to processing. Dietary supplements can be another source of viatmins in the modern diet. Dietary supplements contain some combination of vitamins, minerals, herbs, botanicals, amino acids, enzymes or extracts. Dietary supplements cannot replace the benefits of a diet containing a wide variety of foods. Vitamins must be absorbed by the body in order to perform their functions. Approxminately 40-90% of vitamins are absorbed in the small intestine. Fat-soluble vitamins require fat in the diet to be absorbed.
