**15. Minerals**

Minerals are inorganic elements present in the soil and water and are important for the body to stay healthy. According to the human body demands, dietary minerals are two types, such as macro-minerals those are required in large amounts (e.g. calcium, phosphorus, magnesium, sodium, potassium, and sulfur), and micro- or trace-minerals those are required very small amounts (e.g. chromium, copper, cobalt, iron, fluorine, manganese, iodine, molybdenum, zinc, and selenium) [144].
