Minerals represent from 0.2% to 0.3% of the total intake of all nutrients in the diet. They are so potent and so important that without them the organism would not be able to utilize all the other food components. The main mass of these minerals constitute the

macroelements

, and the

trace elements

constitute less than one-hundredth of one percent of the total mass of daily eaten nutrients. Foods that are good sources of some minerals are given in Table 4.1. Dietary minerals are necessary for maintenance of normal cellular metabolism and tissue function.
