An antioxidant is a substance that helps to protect cells from damage caused by free radicals, which are unstable molecules that can harm cellular structures. Free radicals are generated in the body through metabolic processes, environmental factors (like pollution, radiation, and cigarette smoke), and certain foods.
Antioxidants can neutralize free radicals by donating an electron, thereby preventing them from causing cellular damage. This protective effect may reduce the risk of chronic diseases, such as heart disease, cancer, and neurodegenerative disorders, and may also play a role in slowing the aging process.
Antioxidants can be found in various foods, particularly fruits, vegetables, nuts, seeds, and whole grains. Some well-known antioxidants include vitamin C, vitamin E, beta-carotene, selenium, and flavonoids. While antioxidants are beneficial, it's essential to consume them as part of a balanced diet rather than in excess, as high doses of certain antioxidant supplements can have adverse effects.
