Milk is one of the most important food commodities in the world and its consumption has grown, particularly in developing countries which have exp erienced strong economic growth and urbanization in recent decades. As a substantial source of several nutrients such as pr oteins, enzymes, fats, vitamins and essential elements (also known as minerals), mi lk plays a key role during all phases of human life. Rapid growth during infancy and early childhoo d creates high demand for the nutrients that milk provides. This development phase requir es a balanced amount of different elements, as mineral deficiencies may impair body devel opment whilst excessive mineral intake may increase the osmotic load and cause complicati ons in the developing kidneys of a child. Essential elements such as Ca, K, Mg, Na and P have several physiological functions in the tissue struct ure of humans and other animals, su ch as maintaining osmotic/electrolyte balance, and acting as a cofactor for many enzymes. Deficiencies in these essenti al elements causes disturbances
