VITAMIN D BENEFITS AND LACKS
Vitamin D is very important for the health of the organism and plays a fundamental role especially for the deposition of these minerals in the bones.
Vitamin D also contributes to the health of:
- nervous system,
- immune system
- muscles, including the heart muscle.
Therefore, when vitamin D is lacking, there are negative effects on the general health of the organism, but be careful even an excess can be harmful.
Vitamin D therefore improves the overall health of the body.
Among the fundamental functions of vitamin D are the protection and strengthening of the bones and the immune system.
Vitamin D contributes to the absorption of calcium, which is essential for bones and the body’s supporting structures, and to the maintenance of the correct levels of phosphorus in the blood. Its action is also essential for the prevention of cancer and multiple sclerosis.
Vitamin D also treats osteoporosis, muscle aches, hypertension, diabetes, psoriasis and muscle weakness.
Vitamin D lack
Vitamin D lack/deficiency has negative effects especially on the bones; it can, in fact, cause rickets in children or osteomalacia in adults; and promotes osteoporosis.
When there is a lack of vitamin D, there is an abnormal absorption of calcium in the intestinal tract and a retention of phosphorus in the kidney, resulting in a defect in mineralization of the skeleton.
A vitamin D lack also has negative effects on the muscles.
Furthermore, the importance of vitamin D for the immune system; in fact it has been observed in several studies that a vitamin D deficiency is associated with a higher vulnerability to viral and bacterial infections and there is even talk of a possible association between vitamin D deficiency and some types of neoplasms.
Vitamin D benefits and lacks/deficiencies
To prevent a lack of vitamin D, you should above all be sufficiently exposed to the sun, taking advantage of spring and summer, when the body stores vitamin D to be used even in winter.
However, a balance must be found between the need to guarantee the body adequate levels of vitamin D and that of protecting the skin from the aggression of the sun’s rays; it is therefore necessary to follow some rules:
- avoid exposing yourself for too long and during the hottest hours;
- for fair-skinned people an exposure of about 10-15 minutes is sufficient, while those with dark skin need three to six times longer, depending on the colour of the skin.
