The 1999-2000 National Health and Nutrition Examination Survey (NHANES
99-00) provides the most recent dietary data from a large nationally
representative sample. Trends in energy and nutrient intake across the
life span are described. Energy intake decreases considerably with
age, resulting in substantial declines in nutrient intake, especially
in certain demographic groups. Food group patterns and vitamin
supplement usage also vary with age. Certain serum nutrient levels are
described, and compared with data from NHANES, 1988-94.
