Requirement for mineral elements

Mineral substances are an obligatory component of food which includes over 60 various chemical elements. In an organism they are necessary for normal functioning of many systems. So, iron, copper, manganese, nickel, cobalt participate in krovetvorenii; phosphorus and calcium are structural elements of a bone fabric, without them regeneration of fabrics is impossible; fluorine participates in development and growth of a teeth; sodium and kaly support kislotno the basic balance of an organism.

The Usual diet to the full sates an organism with necessary mineral substances, except chloride of sodium which it is artificial is entered into food.

All mineral substances share on two groups - macro-and microcells. The maintenance of macrocells (calcium, phosphorus, kalija, sodium, magnesium) in organism fabrics makes more than 0,01/kg Microcells contain in small amounts - 0,01-0,00001/kg To them concern iodine, fluorine, nickel, cobalt, copper.

For an organism not indifferently parity of some mineral elements with each other. For example, calcium and phosphorus should arrive with food in the ratio 1:1,5, and calcium and nagny - in the ratio 1:0,5. Such parity promotes good mastering of these elements in an organism.

The Lack or surplus of those or other mineral elements of food or potable water can cause pathological changes in an organism. With them connect development endemicheskih the diseases depending on geographical district where microcells are absent in soil and consequently, and in foodstuff more often. It concerns iodine, copper, iron, nickel, fluorine, etc. For example, at a lack of iodine food arises endemichesky a craw, at absence or an iron lack - anemias, with sh vyshennym the fluorine maintenance in food connect development fljuoroza etc.

Calcium is a constant component of blood, participates in maintenance of nervously-muscular excitability. The role of calcium in the course of blood curling is well-known. The great value has calcium in formation, growth and development of a bone fabric.

Calcium contains in many products, but is better it is acquired at the use of milk and dairy products where it is well balanced with phosphorus and magnesium. Besides, presence of milk and dairy products at a food allowance is capable to raise comprehensibility of calcium and other elements. In other products (bread, meat) it is in an adverse parity with phosphorus and magnesium that stirs to good mastering. The small maintenance of calcium in meat and fish. Daily requirement of calcium - 800 mg.

Phosphorus plays the big role in metabolism processes. He participates in brain activity, in muscular reductions.

The phosphorus Considerable quantity contains in dairy products, eggs, a liver, meat, fish. The requirement of the adult person for phosphorus makes 1200 mg, children of 1500 1800 mg a day.

Kaly participates in maintenance of the kislotno-core of balance of blood, raises deducing from an organism of a liquid and sodium salts. Its daily requirement - 2,5 5 mg. Kaly contains in dry fruit, in peas, a string bean and a potato. Are less rich kaliem cereal, meat and fish products.

Magnesium stimulates peristaltiku guts and raises bile allocation, normalises excitability of nervous system, participates in a cholesteric exchange, reducing its maintenance in blood. Daily requirement - 400 mg. A magnesium source are bread, groats, bean.

Iron participates in krovetvorenii, synthesis ferritina (the squirrel of a liver), haemoglobin. The lack of iron of food leads to an anaemia. Iron possesses ability kumulirovatsja in an organism that serves as reliable protection against an anaemia. Daily norm of consumption of 10-18 mg. Almost all products making a diet, contain iron. Most of all it is in a liver, bean (a string bean, peas), oat groats.

The Food arriving in an organism, has sour reaction which is provided with such products as bread, krupjanye, pasta, meat, fish, eggs, etc. more often. Shift of the kislotno-core of balance in the sour party in an organism adversely affects on health, i.e. Contributes to atherosclerosis development. To normalise the kislotno-core balance, it is necessary to use products with alkaline radicals. Vegetables concern them ^ fruit, milk and dairy-sour products.
