Macronutrients and Their Roles in Aging

Macronutrients are the essential nutrients that are needed in high amounts for healthy aging. Several acute and chronic illnesses such as diabetes, hypertension, atherosclerosis, other cardio-vascular disorders, dementia, bone morphological disorders, etc. are strongly linked to aging. Further, age-related morphological and functional changes are observed in every cell/organ in almost all living organisms. To cope with age-related illnesses, macronutrients such as carbohydrate, protein, and fat have to be supplemented in an ideal manner. Macronutrient supplementation must be planned as per age group, sex, ethnicity, country of origin, etc. to achieve successful aging. The various diet patterns, like the Mediterranean diet, the Japanese diet, the Okinawa diet, etc., strongly suggest that they contain different ratios of macronutrients. Thus, supplementation with the proper ratio of macronutrients in association with other strategies is the best way to achieve healthy aging.
