  1. تغذیه سالمندان

  2. Age-related body changes that influence nutrient needs • Muscle mass decreases so energy requirements decline; physical activity fewer calories • Slower uptake of vitamin A by peripheral tissues, so higher circulating levels • Decline in immune function with increased susceptibility to infection and malignancy ;this may be counteracted with increased intake of vitamins and minerals • Skin synthesis of vitamin D diminishes • Vitamin B6 utilization diminishes • One-third of people over 70 have limited secretion of stomach acid which affects absorption of vitamin B12, folic acid, Ca, Iron and zinc, and partly explains the tendency to depletion and the possible need for supplements of these nutrients
