Why does the body need food with a balanced vitamin D content?
A person needs a whole range of complex vitamins and microelements for the normal functioning of the body, but some of them play a special role in our body’s vital activity.
Calcium is needed for bones and teeth, without it, the body will not get stronger. In addition, it takes part in the muscles, immune and nervous systems, by contributing to blood clotting. Phosphorus is also necessary for bones and teeth, and for muscles, it participates in the reproduction and division of cells, reduces the likelihood of sand and kidney stones, and is involved in all bodily processes. But the human body is not able to absorb calcium and phosphorus without vitamin D. This is what my post is about today.
Due to a lack of vitamin D, bones become weak, immunity goes down, and a variety of diseases can develop, including cardiovascular and cancerous ones. Its deficiency leads to health problems ending in death.
In many countries, the shortage is compensated by special treatment with ultraviolet rays of some products: milk, mushrooms, cottage cheese, kefir. This allows you to exclude some health problems among the population. Countries are particularly at risk where, due to climatic conditions, there is a clear lack of sun.
It is very important at an early age to give children enough Vitamin D, otherwise, in the first months of life, rickets can begin to develop, leading to serious complications. In adulthood, a person needs 600 IU per day of vitamin D, children need 400 IU, and older people up to 800 IU.
It is possible to provide the body with this substance in several ways: by means of direct exposure of the skin to ultraviolet rays, by taking multivitamin complexes, and also by adjusting the diet.
To saturate the body with vitamin D, you need to be in the open sun for about an hour a week, without using protective agents. Ultraviolet rays, reaching the open skin, help a person to synthesize this substance.
With food, it is problematic to fully supply the right amount, but still, the diet needs to be diversified with products having a high content of this substance. These products include chicken, eggs, sardines, tuna, mackerel or salmon.
If you take vitamin D as a separate component, then there is a risk of overdosing, which also adversely affects health, leading to intoxication. Therefore, sunbathing is considered the best option, but too much is also harmful. It is enough to be in the sun 2-3 times a week for 15-20 minutes.
