According to pathologist Dr. Mohammed Al-Bayati, “Damage to the immune system is rapidly reversible after removal of the true insulting agent or treatment of the true causes.” A healthy immune system is a function of a healthy life and one of its greatest depressors is malnutrition. “Atrophy in the lymphoid tissue in people suffering from malnutrition has been known since 1925. Malnutrition causes severe atrophy in the thymus and lymphoid organs and impairs the function of the T cells. These changes are reversible by feeding. The size of the thymus in malnourished children increased from 20% of normal to 107% of normal, following nine weeks of feeding,” reports Al-Bayati.
