Author Description

The core of this thesis describes the results of a 17-week randomized placebo controlled intervention trial in frail elders (n=161). The effects of nutrient dense foods (enriched with 25-100% of the Dutch RDA of multiple vitamins and minerals) vs regular foods, and an all-round exercise program vs a social program on indicators of the nutritional and health status have been investigated. Indicators such as sensory performance, appetite, dietary intake, body composition, blood nutrient and functional biochemical health indices were examined. Additionally, the nutrient dense foods were evaluated on hedonic aspects.
