摘要

The finalized USDA Dietary Guidelines are anticipated next spring. The committee reported low dietary intakes of vitamin E among children, and vitamins A, C, E and folate were considered low enough to be of concern among adults. The difficulties with keeping everyone in the food segment happy starts with the second paragraph of the Nutrient Intake Goals, where the report notes, "One premise of the Dietary Guidelines Advisory Committee is nutrients consumed should come primarily from foods." The commentary notes studies show consumers who eat a diet rich in beta-carotene, the natural precursor of vitamin A, have a lower rate of several kinds of cancer. In contrast, studies have not shown taking beta-carotene in pill form decreases the risk of cancer.
