Minerals
The role of minerals in the political transformation of matter is definitely wider than the role of vitamins. Mineral components are necessary in the system for building purposes (Especially in bone tissue), are part of the body fluids, some enzymes, high -energy relationships, etc.. They also affect the regulation of organ and systemic activities. The special role of minerals is maintained in maintaining homeostasis conditions (acid-base balance, osmotic pressure).
Macro- and microelements contained in food and in drinking water compensate for the losses of minerals in excretion and political secretions, in exfoliating epithelium etc.. The economy of some mineral components of basic importance for the system, e.g.. calcium, punish, potassium, is subject to strict hormonal control. The regulatory function is also fulfilled by interdependencies existing between individual components, e.g.. Between calcium and phosphorus or soda and potassium.
Taking into account only quantitative relations, it was accepted to divide minerals into macro- and microelements. Ingredients include the macroelements necessary for human food, for which the daily demand is over 100 mg. They belong to them: calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulfur. Some also include iron here, Despite the much lower demand compared to the elements mentioned above.
List of microelements necessary in nutrition (so -called. trace elements) It is not fully established so far. We belong to them: copper, zinc, mangan, iodine, fluor, kobalt, harness, molybdenum, chrom. The possibility of including the following elements in this list is still being considered: nickel, tin, They are, silicon. You can only judge about the importance of some of these microelements in human physiology (as before) based on indirect data. Apart from iodine, there is no reliable levels of microelements. This gap is filled with so -called. recommendations, based on approximate estimation of needs.
Determining the role and levels of the demand for microelements is currently a leading task in the field of human nutrition physiology and in medical sciences.
