a M = male, F = female, P/L = pregnant and/or lactating.

NOTE: Food water intake reflects the water content of all foods consumed (excluding water from foods reported in a beverage combination). Data are limited to individuals who provided a valid response to the question “How much plain drinking water do you usually drink in a 24-hour period? Include only plain tap or spring water,” and who provided a complete and reliable 24-hour dietary recall on Day 1. The intake distributions for infants 2–6 and 7–12 months and children 1–3 years of age are unadjusted. Means and percentiles for these groups were computed using SAS PROC UNIVARIATE. For all other groups, data were adjusted using the Iowa State University method to provide estimates of usual intake. Means, standard errors, and percentiles were obtained using C-Side. Standard errors were estimated via jackknife replication. Each standard error has 49 degrees of freedom. Infants and children fed human milk and females who had “blank but applicable” pregnancy or lactating status data or who responded “I don’t know” to questions on pregnancy or lactating status were excluded from the analysis.
