Manganese is a mineral which is important for the activation of various enzymes in the body, that are involved in energy metabolism. It is also necessary for the development of bone tissue. Manganese is an antioxidant: it protects the cells in the body from free radicals. Free radicals play a role in aging processes.
Manganese is found in cereals, rice and nuts. Other sources are (leafy) vegetables, fruits, meat, fish and tea. Pineapple is high in manganese.
