The immune system protects the body by helping it to ward-off and recover from various diseases. While stress reduction and regular exercise are known to assist in strengthening the immune system, the types of food consumed make the largest contribution to a healthy immune system. Eating a well-balanced diet including a variety of healthful foods will boost this system's effectiveness like nothing else.

The chief destructive force that the immune system has to contend with is free radicals. Free radicals damage healthy cells by causing cell alterations (mutations) which can lead to serious illnesses such as Heart disease and Cancer. However, certain substances present in food can destroy free radicals. These substances are called antioxidants.
