Manganese is an essential trace mineral that is concentrated primarily in the bone, liver, pancreas, and brain. Manganese is a component of a variety of enzymes involved in critical body functions.
Deficiencies: Manganese deficiencies in animals produce abnormalities in brain function, glucose tolerance, reproduction, and skeletal and cartilage formation. In humans, gross deficiencies have not been documented but studies suggest the mineral is important to maintain the integrity of the skin, bone, and menstrual cycle, and in cholesterol metabolism.
Food sources: Excellent sources of manganese include pecans, peanuts, pineapple fruit and juice, oatmeal, shredded wheat, and raisin bran cereal. Good sources are beans (pinto, lima, navy), rice, spinach, sweet potato, and whole wheat bread.
