The onset of senescence brings about several non-communicable diseases, most of which are directly related to the shortage of certain nutrients in the ageing bodies. Several older people are at a risk of developing nutrient deficiencies, which can result in chronic diseases decreasing life expectancy or quality of living.
Up until now, there were several misconceptions about the nutrient requirements for the elderly citizens, mostly because health data required for nutrient estimation was not directly derived from the senile generation, but was extrapolated from the studies performed on younger people. However, recent studies have thrown new light on the nutritional requirements of the elderly. Scientific studies now aim to estimate not only the amount of nutrients required for preventing a deficiency, but also the nutrition necessary for preventing a chronic non-communicable disease or its symptoms.
