Antioxidants Nutrietion

What Are Antioxidants?

Antioxidants are chemicals that occur naturally in foods. They help fight the potentially harmful effects of unstable substances known as free radicals. Free radicals are compounds formed during the body’s normal metabolic processes and through general wear and tear on body cells. Infections, UV light (from both the sun and artificial tanning machines), cigarette smoke, pollution and even exercise can all generate free radicals.

What Do Antioxidants Do?

Antioxidants come to the rescue of healthy body cells by destroying some of the free radicals that would otherwise harm and damage our healthy cells.

Our bodies make their own antioxidants, but they also make use of antioxidants in the foods we eat. Studies have shown there are many benefits from eating plenty of antioxidant-rich foods which, together with an active and balanced lifestyle, can help reduce the risk of certain cancers and heart disease.
