Total fluid intake of younger men (YM), older men (OM), younger women (YW), and older women (OW) with comparisons to recommended (Rec) fluid intakes. The total fluid intake included water consumed ad libitum and from the foods and beverages provided. The third National Health and Nutrition Examination Survey (NHANES III) 50th percentile is the median total fluid intake for the respective groups. These values for the YM and YW are used as the “adequate intake” of water set by the Food and Nutrition Board for all adults, independent of age (2). Rec 1 = 30 mL/kg body wt (13, 14); Rec 2 = 1 mL/kcal energy consumed (15); Rec 3 = 100 mL/kg for first 10 kg, 50 mL/kg for next 10 kg, and 15 mL for each additional kilogram of body weight (16).
