Before analyzing the reasons for the “disappearance” of calcium in the bone tissue, in this chapter we will find out what the biological role of calcium in metabolism is, and also consider the norms of its consumption for different age groups of people.

First, it should be noted that 99% of calcium is found in bones and teeth, where it is not only their main component, but is also stored for the needs of the whole organism. Secondly, the amount of calcium in the bones can change, but its content in the blood serum is STRICTLY CONSTANT – 1% of the total blood composition. It is the importance of maintaining this indicator – 1%, that can lead to leaching of calcium from the bones. Why? Read on. Lack of calcium leads to hundreds of diseases as:

1. Calcium ions are involved in the processes of hematopoiesis. Only this impaired function will cause an avalanche of negative health consequences.

2. Calcium regulates the growth and activity of cells in all types of tissues. And for connective tissue, which includes bones, teeth, cartilage and ligaments, calcium is the main supporting element.

3. Creates resistance to infections, having anti-inflammatory properties, being an integral part of the appropriate hormones and enzymes.

4. Reduces meteorological dependence, because the so-called “play of vessels” when atmospheric pressure changes causes a lot of trouble to its owner.

5. Helps reduce vascular permeability by forming bonds between fats and proteins – the structural elements of the membranes of all cells, including vascular ones. If the gums bleed, then the same symptom appears in the depths of our body. We just don’t see it, but we clearly feel weakness, fatigue, etc.

6. SA ions are necessary for the transmission of nerve impulses. In children, a violation of this process is manifested in increased nervous excitability, whims, outbursts of irritation, a tendency to bite nails, and often move legs and arms. In adults, cramps of the calf muscles occur, blood pressure rises.
7. Calcium prevents the accumulation of strontium-90 and lead in the body, as it is their antagonist. These elements are enough in the environment to take its place in the crystal lattice of the same bone or dental tissue in the absence of calcium. In the periodic table, these metals stand side by side, therefore, they have parameters similar to calcium. But in in a living organism, they cannot fulfill its biological duties.

8. Calcium alkalizes the internal environment of the body. Next, we will dwell on this important duty of calcium in detail.

What are the intake rates for calcium?

We have seen how diverse the biological role of calcium in our body. This is understandable if you remember how widely it is represented in nature. And “we are what we eat” – agree that it is difficult to disagree with this statement, which came to us from healers from the depths of centuries.

So, children under 3 years of age require 600 mg of calcium per day, adolescents from 1000 to 1200 mg, adults – 800 – 1200, and during pregnancy and lactation up to 2000 mg of calcium. Moreover, milk and dairy products, contrary to popular belief, are not the main sources of calcium. Recall that the biological role of calcium is significantly reduced during the heat treatment of food. The city dweller does not imagine the taste of milk “from under the cow” at all. And another example. The Japanese practically do not use milk in their diet, however, the frequency of fractures or joint diseases in them is even less common than in the average European or American.

In science, the minimum daily allowance is determined in accordance with the amount of excretion of a particular substance from the body. So, calcium is excreted daily in the urine in the amount of 150-200 mg, with feces 100-150 mg. Slightly excreted with sweat. Thus, the daily physiological loss of calcium is no more than 300 mg.
