Oh what complete bs. Do you really believe that using sunscreen prevents all
UVB or UVA from getting through? Have you even read the literature? Unless
you have very dark skin, typically brown/black, and if you live in areas
that don't get much sun (like extreme north or south), you get plenty of
sun. Do you put on sunscreen walking to the car, to the mall, to the
mailbox?

Feel free to die of skin cancer if that's your choice....

If it were the case that casual sun exposure provided sufficient
Vitamin D to meet our daily needs we would not have the current
epidemic of Vitamin D insufficiency.
http://www.ajcn.org/cgi/content/abstract/85/3/860 shows the 9 out of
10 UK adults have less than 75nmol/L in the Winter and 60% remain
deficient during the Summer.

Feel free to die of those 17 cancers that thrive in Vitamin D
insufficient bodies if that's your choice but I'd rather risk skin
cancer than all this lot. lung, prostate, colon, breast ovary uterus
bladder Oesophagus kidney pancreas stomach gallbladder larynx Hodgkin
lymphoma non Hodgkin lymphoma myeloma For each skin cancer death there
are over 30 attibutable to the effects of low vitamin D status.

Even melanoma is inversly related to vitamin D status. Those people
with melanoma who have the highest vitamin D status have the best
prognosis and the fewest repeats. The central cause of melanoma, is
not sun exposure, but an imbalance in the omega 6 to 3 fat ratio.
Epidemiological, experimental, and mechanistic data implicate omega-6
fat as stimulators and long-chain omega-3 fats as inhibitors of
development and progression of a range of human cancers, including
melanoma.
Rather than promote the use of sunscreens and severely limit the
valuable benefits of UV-B radiation, we should encourage the judicious
use of clothing and timed sun exposure.
