Why we need foods high in Vitamin D ?

Vitamin D is an essential nutriment, because it allows the captation of calcium by bones and teeth, so eat foods high in vitamin D. Without vitamin D, the skeleton does not strengthen, it becomes brittle (osteoporosis), and it is the same for teeth. Recommended dose of vitamin D is 5 micrograms daily.

The synthesis of vitamin D can be done when the sun's rays meet the 7-dehydrocholesterol, it is provitamin D (cholesterol derivative), meaning that the mere exposure to the sun can produce vitamin D. A lack of vitamin D can comes from a lack of sun exposure and can lead to rickets.
