Nutrition and aging: dietary intake of "apparently healthy" elderly (Dutch Nutrition Surveillance System).

The dietary intake (assessed through dietary history) of 539 apparently healthy, independently living elderly aged 65-79 years, was evaluated in a nationwide random sample. Except for pyridoxine, the intake of vitamins, minerals, and water was adequate according to the Dutch recommended dietary allowances. Fat intake (40 energy%) as well as P/S ratio (0.41) was assessed as being unfavorable, whereas the intake of vitamin B6 was marginal. The prevalence of obesity was higher among the women, while food selection was healthier as reflected in the higher nutrient density than among the men. Food consumption of elderly men (26%) and women (33%) on a dietary regimen was more prudent and nutrient density higher than among the elderly not on a diet. Our results are in accordance with previous food consumption studies among elderly in The Netherlands, but differ substantially from dietary intake figures for American elderly. Although the intake of energy and nutrients was lower among elderly men than among younger men, we conclude that age per se is not an important determinant of dietary intake among Dutch apparently healthy elderly aged 65-79 years.
