NOTE: Data are limited to individuals who provided a complete and reliable 24-hour dietary recall on day 1. Estimates represent the unadjusted distribution of the intake reported per individual (the distribution of the data does not meet the assumptions of the Iowa State University method, i.e., the C-Side program). The mean and percentiles for all distributions were calculated using SAS PROC UNIVARIATE. All sample weights greater than 40,000 were truncated to 40,000 to reduce the influence of extreme intake patterns. Food composition data are from the NDS-R Food and Nutrient Database, Version 30, 1999, Nutrition Coordinating Center, University of Minnesota. Infants and children fed human milk and females who had “blank but applicable” pregnancy and lactating status data or who responded “I don’t know” to questions on pregnancy and lactating status were excluded from all analyses. Females who were both pregnant and lactating were included in both the Pregnant and Lactating categories. The sample sizes for the Pregnant and Lactating categories were very small so their estimates of usual intake distributions are not reliable.
