Dietary intake of selected vitamins for the United States population: 1999-2000.

This report presents dietary intake estimates for selected B-vitamins, carotenes, and vitamins A, C, and E from the National Health and Nutrition Examination Survey, 1999-2000, for the U.S. population. Vitamin intakes are estimated from one 24-hour dietary recall interview. Population means, medians, and standard errors of the mean are weighted to produce national estimates, and are presented by sex and age groups. Assessment of dietary intakes is an important part of monitoring the nutritional status of the U.S. population.
