Explanation: 

Detailed explanation-1: -Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.” The body makes some of the antioxidants that it uses to neutralize free radicals. These antioxidants are called endogenous antioxidants.

Detailed explanation-2: -Antioxidants can play a role in cancer prevention. Antioxidants work by tracking down free radicals and neutralizing their harmful effects. That helps keep more of the body’s cells healthy and less susceptible to becoming cancerous.

Detailed explanation-3: -Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural “off” switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.

Detailed explanation-4: -Antioxidants are the molecules that reduce the chance of ageing by diminishing or maintaining the level of oxidants with or without free radical activity. Therefore, to many people, “antioxidants” and “anti-aging” go hand-in-hand.

Detailed explanation-5: -Antioxidants are substances that may protect your cells against free radicals, which may play a role in heart disease, cancer and other diseases. Free radicals are molecules produced when your body breaks down food or when you’re exposed to tobacco smoke or radiation.
