Changes in nutritional needs as you age
Reduces the ability to absorb certain nutrients
As you get older, the ability to absorb, use certain nutrients becomes less effective.
Because the body produces fewer digestive substances. For example, older people may have problems absorbing vitamin B12 due to a decrease in acid levels in the stomach.
Besides, some drugs change the way nutrients are absorbed or metabolized. For example, anticonvulsants can reduce folate absorption.
