Antioxidants are molecules that neutralize free radicals, unstable molecules that can harm your cells. Free radicals are constantly being formed in your body.
Without antioxidants, free radicals would cause serious harm very quickly, eventually resulting in death.
However, free radicals also serve important functions that are essential for health. For example, your immune cells use free radicals to fight infections. As a result, your body needs to maintain a certain balance of free radicals and antioxidants. When free radicals outnumber antioxidants, it can lead to a state called oxidative stress.
Prolonged oxidative stress can damage your DNA and other important molecules in your body. Sometimes it even leads to cell death. Damage to your DNA increases your risk of cancer, and some scientists have theorized that it plays a pivotal role in the aging process.
