Lesson 4

• With age, intracellular fluid is lost, resulting in decreased total body fluids. Whereas water comprises approximately 60% of body weight in younger adults, it constitutes 50% or less of body weight in older adults.
• The Institute of Medicine recommends fluid intake for men over the age of 50 years of 3.7 L/day

  For Women of the same age group 2.7 L/day (equivalent to 11 to 15 glasses containing 8 oz).

  Some health conditions may require less fluid Intake.
