Define Nutritional Requirement and Dietary Modifications in the Diet of the Elderlu?

The nutritional status influences the age-related rate of functional decline in many organ systems. The progressive changes in body composition associated with ageing,Such as loss of bone and lean body mass are affected to a great extent by the nutritional status of an individual. Moreover, the evidence is now undisputed that diet and nutrition are directly linked to many of the chronic diseases afflicting older adults.  A consideration of recommended dietary allowances (RDAs) for older adults must recognize each of these aspects of the relationship between nutrition and ageing.

The nutritional requirements for elderly that are presently used have to rely on extrapolation from data collected on younger people. A growing body of scientific Literature provides ample evidence that nutrient requirements are altered for the ageing individuals and a need exists for redefining or RDAs. Further, the nutrient requirements may not be readily met through dietary intakes which are very often inadequate in older adults, therefore consumption of nutrition supplements may need to be endorsed.
