Antioxidants

Definition

Antioxidants are molecules that inhibit the oxidation of other molecules, preventing cellular damage and promoting overall health. They play a vital role in traditional dietary practices by neutralizing harmful free radicals, which can lead to chronic diseases and aging. Many foods rich in antioxidants, such as fruits, vegetables, nuts, and whole grains, have been integral to various cultural diets, linking them to health benefits and enhanced longevity.
