Toxic byproducts of metabolism and biological aging
The chemical reactions of normal everyday physiology produce byproducts. In particular, cellular energy production produces reactive oxygen species as a byproduct, which can damage DNA, proteins, and lipids. Although we have natural antioxidant defenses, oxidative damage can still occur, especially if we don’t take in adequate antioxidants from our diet.3 Oxidative damage accelerates aging. Read more...
