Among the elements that make up our body, calcium ranks fifth after carbon, oxygen, hydrogen and nitrogen, according to Pannochka, an online publication for girls and women aged 14 to 35.. net Calcium is part of the skeleton, teeth, nails, hair. The body normally contains about 1200 g of calcium, 99% of this amount is concentrated in the bones.

Two processes are constantly going on: the resorption of bone substance with the release of released calcium and phosphorus into the bloodstream and the deposition of phosphorus-calcium salts in bone tissue. In growing children, the skeleton is completely renewed in 1-2 years, in adults - in 10-12 years..

In an adult, up to 700 mg of calcium is excreted from the bone tissue per day and the same amount is deposited again.. Thus, the bone tissue, in addition to the supporting function, plays the role of a depot of calcium and phosphorus, from where the body extracts them with a lack of intake from food.. For example, when atmospheric pressure drops, the body needs more calcium than usual to maintain balance.. If there are no reserves in the blood, then it is intensively extracted from the bones. When the process goes beyond the norm, pathology develops, more often in the elderly, and they say: “Oh, how the bones hurt! This is bad weather."

When little calcium enters the body for a long time, it can be replaced by strontium, since their molecular structures are similar. And yet the molecular lattice of strontium is larger than that of calcium. From here there are changes in the bones and joints - " These processes are especially active after 35-40 years, when the body begins to " And as a result - osteoporosis (resorption of bone tissue), numerous diseases of the nervous and cardiovascular systems.

Calcium also neutralizes harmful acids. The less foods that give an acidic blood reaction (meat, cheese, white flour products, refined sugar and animal fats) in food, the less the need for calcium, the better the condition of bones and teeth..

Scientists note two more features associated with calcium. A good calcium reserve, “earned” in youth, keeps the body in a healthy state for many years.. The higher the calcium concentration in the blood serum, the greater the patient's chances of recovery..

Calcium maintains vascular tone by influencing the tone of smooth muscles located in the walls of blood vessels. Controls contraction and relaxation of skeletal muscles. Being a sodium antagonist (which retains water in the body), it promotes the excretion (along with water) of salts of heavy metals and radionuclides. In addition to the above, calcium is a powerful antioxidant and anti-stress.

The main signs of calcium metabolism disorders:.

• dysplasia in children;

• rickety changes in the proportions of the skull due to softening of the bones ("

• flattening of the pelvic bones with a change in its transverse dimensions, which in the future may have serious consequences for women in labor and their children due to the difficulty in passing the baby's head through the birth canal;

• curvature of the spine, bones of the lower extremities (O-shaped or X-shaped legs);

• sweating, irritability, early baldness, dull hair color;

• tendency to allergic rashes;

• violation of the growth of teeth, early destruction of enamel;

• poor blood clotting, tendency to prolonged bleeding;

• multiple bruises on the body due to bleeding from tissue capillaries;

• tendency to convulsive reactions, muscle cramps;

• frequent constipation.

The daily requirement for calcium varies with age, from 1500 mg for nursing mothers, 1200 mg for children aged 6-7 years to 800 mg for everyone else.

Calcium absorption is negatively affected by dietary excess of phosphorus, magnesium and potassium, as well as excess or lack of fat..

Some acids (inositol-phosphoric, oxalic) form strong insoluble compounds with calcium that are not absorbed by the body. In particular, calcium from sorrel, spinach, wheat and other cereal products containing a significant amount of inositol-phosphoric acid is poorly absorbed - only 20-30% of the total amount taken.. Until recently, milk and cheese were thought to be the best sources of calcium.. It is now known that milk contains a calcium that is unusual for the human body..

In order to assimilate it, you need to spend a lot of energy, including part of your own calcium supply..

Cheeses tend to be loaded with fats, salt, and dyes.. Therefore, natural foods should be considered the main sources of calcium: fish liver, seafood, raw egg yolk, beans, cabbage, celery, cottage cheese, apricots, currants, grapes, oranges, pineapples, parsley, spinach. These products contain not only calcium, but also phosphorus, as well as vitamins D, C, B.
