Sugar is known as immune suppressant. No matter what form it takes, sugar paralyzes the immune system in many ways; It reduce the germ killing ability of white blood cells. It reduces production of antibodies against foreign invaders. It interferes with the transport of Vitamin C, one of the important element for immune function. It causes mineral imbalances and allergic reactions and both of they weaken immune system. The reduction in taking sugar and sugar products and refine carbohydrates may help to achieve good health.
