What you need to know about calcium and its benefits to the body
Calcium in the products of everyday nutrition is incredibly important for the human body. This natural mineral, which accounts for the largest proportion, is mainly concentrated in the teeth and bone tissue. It is found in the blood and extracellular fluids: here it is not more than one percent, but it does not diminish its significance for life and health, because it reduces the permeability of the vessel walls, being a protection against the penetration of allergens and viruses into the cell, and helping the blood to clot.
All organs and systems need calcium, so the body will try to get it by all means, even literally sucking out the required volumes from the bones, replenishing the reserves in the blood. Therefore, in order to protect bones from fragility, doctors strongly recommend to eat food rich in calcium
What is necessary to know about the digestibility of this element:
- If the level of calcium in the blood drops, it does not mean that the diet is low in the foods from which it comes. This can talk about other problems – with the parathyroid gland or kidneys. A low level of calcium in the blood can also be provoked by a deficiency of magnesium or vitamin D. However, whatever the calcium deficiency may cause, it can lead to osteoporosis due to the loss of bone mass.
- Food is the ideal source of this mineral, and it is theoretically possible to get it in the right norms. However, taking into account today’s eating habits of a person, the result is the indicators that are twice lower than the required. Absorption of calcium from mixed foods is only 40% of its content.
- Even the knowledge of the products that are rich in calcium is not yet a guarantee of its qualitative assimilation. In particular, in cereals, there are substances that form compounds with calcium that the body can not absorb. To get this mineral, it must be dissolved by the gastric juice, and this is interfered by carbohydrates, for example, from sweets, because to be digested, they require the production of alkali, interfering with the processing of calcium.
- To ensure that calcium is absorbed, it is necessary to replenish vitamin D3. Vitamin D, called solar, is produced in the body in the sun. In foods it is found in rather scant amounts. It is in fish, liver, and egg yolks.
- To find out whether this important element is getting enough into the body with food every day, it will take at least a week to keep a diary and calcium calculator. For such a period, the standard diet will be fully displayed in the records, and it will be possible to give an objective assessment of how calcium intake corresponds to age and sex.
