Old age nutrition

  • Effects of aging:
  • Energy needs decline.
  • 67% due to decreased physical activity
  • 33% due to decreased BMR (loss of muscle mass due to inactivity)

This can lead to insufficient essential nutrient content in meals that are calorically adequate. Vitamin, mineral absorption may change, leading to changing dietary requirements.Fat distribution patterns change, so skinfold thickness becomes a less accurate measure of total body fat. In the young fat is mostly subcutaneous.In the elderly it is mostly intra-abdominal and intramuscular. Special nutritional problems are also associated with aging.
