Minerals are essential compounds (exogenous), and therefore must be delivered to the body with food. Body needs at least 14 minerals to work properly. Although they do not serve the energy, but are building material, and they are involved in transporting oxygen to the cells, maintaining acid-base balance, and part of the cells, hormones, enzymes and body fluids.
Minerals account for about 4% of body weight.
In the human body recovered about forty of chemical elements, of which the vast majority occur in teeth and bones - about 55% of the total amount of magnesium, 85-95% phosphorus and 99% calcium. The amount of the elements present in the body depends on the type of tissue and the function they perform. The largest amounts of sulfur are in the hair, nails and skin.
In cells the most popular mineral is potassium, iodine dominates in the thyroid, iron dominates in hemoglobin, and in body fluids dominating in sodium. Due to the amount of minerals in the body we divide them into macro-and microelements. For macroelements we include those whose daily needs of more than 100mg.
MICROELEMENTS: zinc, molybdenum, chromium, iron, copper, manganese, iodine, fluorine, selenium.
MACROELEMENTS: calcium, phosphorus, magnesium, potassium, chloride, selenium, sodium.
Is necessary to build healthy teeth and strong bones, promotes blood clotting and affects normal muscle contractility. Its deficiency may lead to decalcification of body. The calcium contained in plant foods (cabbage, broccoli) is absorbed more difficult than that contained in animal products because the best source of calcium include cheese, fish and milk.
Magnesium is important for proper formation of bones and teeth, proper functioning of the nervous system and cardiovascular system. Its deficiency may lead to cardiovascular disorders, attention deficit hyperactivity disorder, convulsions or cardiac disorders. It may also cause a condition called tetany.
Sources of magnesium include green leafy vegetables, corn, bananas, germ of cereals, bran, almonds, nuts, chocolate.
He is involved in the metabolism of carbohydrate and energy metabolism. He is responsible for proper muscle contraction, acid-base balance, as well as conduction of nerve tissue.
Potassium is often observed in foods, and the content of this element in the human food exceeds demand. Potassium is present in vegetables and fruits, meat and offals, grains. Its deficiency can occur as a result of diarrhea, fasting, use of diuretics, or excessive sweating.
