“Some
of the widespread vitamin D deficiency in modern America is likely the result
of decades of promotion of sun safety to reduce the incidence of skin cancer.
Vitamin D is the only vitamin humans can manufacture, and this process happens
in the skin when it's exposed to sunlight. Sunscreen, sunblock and clothing all
interfere with the production of vitamin D in the skin, with sunscreen blocking
upwards of 90 percent of vitamin D production in the skin, Zammit says.” https://www.yahoo.com/beauty/whats-connection-between-vitamin-d-breast-cancer-135448836.html
(Cercetătorii au descoperit apa caldă: deficiența
de vitamina D se datorează campaniilor împotriva expunerii la soare, singura
modalitate prin care corpul uman o poate produce!)
