Vitamin D is produced from the skin by sunlight, are in fact sufficient 15 minutes a day because the body can produce the necessary quantity, also the "excess" produced during the summer, is stored and used in the winter months.
It can integrate it in the case where, for climatic conditions or habits of life, where there is less chance of exposure to sunlight, among the foods most useful for the formation of vitamin D include: milk, butter, egg yolk, cod liver oil, mackerel, salmon, tuna and vegetables.
Integration is recommended when:
- Children, to help the formation and growth of teeth and bones
- Adults, in the case of PMS, menopause, kidney disease, intestinal or liver
- The elderly, osteoporosis
It must pay close attention to the intake of high doses of vitamin D, which should be recommended only in cases of genuine need, and under strict medical supervision, as they may be toxic.
The benefits of Vitamena D: Osteoporosis and Cancer
By comparing the data from many experiments we can say that this fat-soluble vitamin, intervening in the process of absorption of calcium is extremely important for bone health, preventing rickets and osteoporosis, also researchers from the Moores Cancer Center, University of California at San Diego, have found that high levels of vitamin D and proximity to the equator (and therefore greater ability to exploit sunlight) are correlated with a lower incidence of breast cancer.
Although lung cancer would be more easily contrasted with exposure to sunlight and hence a greater production of vitamin D could, as stated by Cetric Garland, head of the Californian study, slowing the separation of lung epithelial cells on the surface itself; because cells usually begin to divide uncontrollably, while the action of vitamin D would lead to release chemicals that can be the butt a kind of glue that would reduce this false separation.
Vitamin D and Heart Disease
At low levels of vitamin D corresponds to a higher incidence of heart disease, this is the result of the study coordinated by Thomas Wang The Harvard Medical School in Boston, after considering more than 1,700 individuals, came to identify some of the vitamin D receptor on the muscles and walls of the heart blood vessels, although detailed studies are needed to better understand the mechanisms behind this correlation.
Vitamin D: the "vitamin of Wonders"
So we can say without doubt that vitamin D is the "wonder vitamin" is the "vitamin of Wonders" as it is able to bring numerous benefits to the body and reduce the incidence of serious diseases: cancer, cardiovascular disease, but including diabetes, rheumatoid arthritis, bone disorders, and even a general enhancement of the immune system level can then increase the defenses organic.
Remind you that they support the sunlight, it is useful to recommend a moderate exposure to sunlight in order to avoid unpleasant consequences.
