Ever heard of the saying, too much of a good thing, well this is the case for iron. Hemochromatosis is when the body has too much iron in its system. Iron attracts bacteria because it is what helps organisms live. We do have defense mechanisms. Chelstors are proteins that lock up iron so infection cannot reach them. A nonchromatic person has more iron, so their macrophages accidentally give bacteria an upper hand. Hemochromatosis is thought to have come from Vikings in Oder to help them come with iron deficiency. Blood letting helps solve hemochromatosis because it reduces the amount of iron in the system.
