Bandodkar, H. No. 346/A, Cavorim, Chandor, Salcete, Goa - 403714, India. E-mail: shreyacolvenkar@gmail.com Perfect health is a prize that has been the goal of mankind throughout all ages. Nutrition provides substrates essential for expression of genetic heritage. It follows therefore, that nutrition might influence the occurrence and severity of degenerative diseases that are associated with aging. Nutritional problems may result from changes associated with aging process itself, from disease or other medical conditions, from interactions with medications, or from all of these. This review summarizes articles that describe the changes in diet associated with aging.
