U.S. Dietary Intake Data from the Third National Health and Nutrition Examination Survey, 1988–1994
TABLE D-1 Mean and Selected Percentiles for Usual Daily Intake of Total Water (mL): United States, NHANES III, 1988–1994
NOTE: Total water intake reflects the sum of plain drinking (tap) water and the water content of all foods and beverages consumed. 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.

TABLE D-3 Mean and Selected Percentiles for Usual Daily Intake of Drinking and Beverage Water (mL): United States, NHANES III, 1988–1994
a M = male, F = female, P/L = pregnant and/or lactating. NOTE: Plain drinking and beverage water intake reflects the sum of plain drinking (tap) water and the water content of all beverages consumed (including 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.

TABLE D-4 Mean and Selected Percentiles for Usual Daily Intake of Food Water (mL): United States, NHANES III, 1988–1994
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.

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.
TABLE D-5 Mean and Selected Percentiles for Usual Daily Intake of Potassium (mg): United States, NHANES III, 1988–1994
F, Pregnant
F, Lactating
NOTE: Data are limited to individuals 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. 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 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.

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

The intake distributions for infants 2–6 and 7–12 months, children 1–3 years of age, and lactating females 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. 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.

TABLE D-9 Mean and Selected Percentiles for Usual Daily Intake of Sodium (mg) by Non-Hispanic Whites: United States, NHANES III, 1988–1994
NOTES: Data are limited to individuals who provided a complete and reliable 24-hour dietary recall on Day 1.

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.
