Abstract

Nutrition plays a strong role in aging. Therefore, the absorption and metabolism of nutrients along with diet are a strong risk factor for aging related diseases. The nutritional requirements for the elderly are different as compared to the younger adults due to factors like drug and nutrient interactions, aging associated conditions, socioeconomic factors, etc. The amount and dosage of minerals, vitamins, and macronutrients are different in the elder population. Assessment of proper nutritional diet is important because in this age group, many people are malnourished that leads to various age-related disorders. Different nutraceuticals like the phytochemicals, carotenoids, vitamin B, D, E, various plant extracts have been reported to have rejuvenating properties. The use of nutraceuticals has beneficial effect on the metabolic and immune systems as they possess anti-oxidant properties.
