Oxidation is a natural chemical process in which molecules lose electrons, often as a result of reacting with oxygen. In the body, oxidation occurs naturally during metabolism when cells convert food into energy.
However, excessive oxidation can produce free radicals - unstable molecules that can damage cells, proteins, and DNA, contributing to aging and diseases such as cancer and heart disease.
A diet rich in antioxidants (like fruits and vegetables) is beneficial to aid with management of free radicals.
