Nutrients and Nutraceuticals in Aging

Aging is accompanied with the incidence of wide range of disease. The best strategy to combat aging and related deteriorative pathologic conditions is nutraceutical interventions. Several dietary compounds and nutraceuticals (dietary fibre, probiotics, fatty acids, antioxidant vitamins, polyphenols, spices, and essential trace elements, etc.) have proven to be beneficial in abating age-related diseases and decelerating aging process. The protective mechanism of these compounds are related to their activities in improving intestinal microbial balance, reducing blood cholesterol, increasing defence systems against oxidative damage in living cells, as well as their role in normal cellular structure and function regulated by enzymes, transporters, sensors and metal-binding molecules.
