Aging: Minimizing Free Radical Damage

Aging is the accumulation of changes that increase the risk of death. The major contributors after age 28 years are the endogenous chemical reactions that, collectively, produce aging changes that exponentially increase the chances for disease and death with age. These reactions constitute the "inborn aging process." This process is the major risk factor for disease and death of the 98% to 99% of cohorts still alive at age 28 in developed countries, where living conditions are now near optimum. The Free Radical Theory of Aging (FRTA) and, simultaneously, the discovery of the ubiquitous, important involvement of endogenous free radical reactions in the metabolism of biologic systems, arose in 1954 from a consideration of aging phenomena from the premise that a single common process, modifiable by genetic and environmental factors, was responsible for the aging and death of all living things. The FRTA postulates that the single common process is the initiation of free radical reactions. These reactions, how...
