Vitamin D leads A major role in enjoying health; As it works to strengthen bones and immunity. Vitamin D is called the “sunshine vitamin,” because sunlight represents the main source of supplying the body with this vitamin, in addition to eating foods rich in it, such as fatty fish. Such as: salmon.
German nutrition expert Daniela Creel explained that vitamin D is of great importance to health. It is important for both bones and muscles, in addition to hormonal and immune function.
Creel added that the body can be supplied with vitamin D by eating foods rich in it, such as fatty marine fish. Such as: salmon and mackerel, in addition to dairy products and vegetable oils.
For his part, German Professor Johannes Wexler said that nutrition only meets about 10% of the need for vitamin D, indicating that the body needs sunlight to meet the rest of the need. Therefore, vitamin D is called the sunshine vitamin.
The head of the Professional Association of Clinical Nutritionists in Germany explained that sunlight helps the body produce vitamin D itself, indicating that for this purpose, the face, arms and hands should be exposed to sunlight at a rate of two to three times a week.
Be careful not to apply sunscreen cream to these parts, otherwise the cream will prevent the sun's rays from penetrating the skin. However, one should – at the same time – not exceed 12 minutes of exposure to the sun without sunscreen cream, in order to limit Risk of skin cancer.
Risk of oversupply
Professor Wexler pointed out that in the case of severe deficiency, as is the case in bedridden people and people suffering from severe obesity, nutritional supplements containing vitamin D can be used, provided that they are taken under the supervision of a doctor.
For its part, the Federal Institute for Risk Assessment in Germany warned of the danger of excessively supplying the body with vitamin D. This leads to hypercalcemia, explaining that in this process calcium is withdrawn from the bones and stored in the blood, which leads to nausea and headaches, and in the long term the risk of kidney damage increases.
