These fact sheets are part of a series that will be posted here. Each undergoes extensive scientific review by recognized experts from the academic and research communities. The information is also reviewed for scientific accuracy and for consistency with the Dietary Guidelines for Americans by the Nutrition Education Subcommittee of the NIH Nutrition Coordinating Committee, the U.S. Department of Agriculture Dietary Guidance Working Group, and the Department of Health and Human Services Nutrition Policy Board Committee on Dietary Guidance.
