The world is in the midst of a global aging trend with the number of individuals over 65 years of age outnumbering those under 5 years of age this decade. In thirty years, the world population over the age of 80 will approach 400 million individuals which is over three times the current number. Research studies have explored a number of scientific approaches over the last century to fight the inevitable outcomes of aging. These efforts can be divided into those that address the basic process of aging as if it was a chronic disease at the cellular and molecular level, and those that approach anti-aging research using methods to prevent or delay chronic age-related diseases of aging to improve the health of individuals as they age. Aging processes are sometimes also classified as intrinsic aging which is the basic process of aging and extrinsic aging consisting of all of the external factors including diet and exercise that influence aging. The rate of aging varies among individuals and “inflammaging” affected by overweight, obesity, and diet has been identified as a potential modifier of the rate of aging. Protein impacts protein synthesis in muscle cells and may be able to reduce the rate of muscle loss and the development of sarcopenia-associated metabolic diseases.
This session will focus on the emerging nutrition science related to the mechanisms of age-related declines in function and metabolism and will detail the effects of protein supplementation, the overall diet, and exercise as anti-aging strategies. A group of recognized experts in the field will review what is known about the links between aging, sarcopenia, muscle cell metabolism, protein synthesis, diet and exercise in terms of impacts on biological aging.
