The two main threats to your health are:

1/ Invasion by bacteria and viruses

2/ Attack by free radicals, and antioxidants are your major defence against this attack.  

What are antioxidants?
Antioxidants protect your cells from damage caused by unstable molecules called free radicals. Free radicals are naturally produced when your body cells use oxygen and when they breakdown food. It also occurs during stress, and the process of detoxification. External factors such as exhaust fumes, smoking, radiation, sunlight and frying or barbecuing food also contribute to free radical damage.

The balance between your in take of antioxidants and free radical exposure may be the balance between life and death.
You can change this by including antioxidant foods to your diet and by routinely taking quality antioxidant supplements
