The reasons are simple - firstly, only some of the frequencies of light
which can "fix" VitD are blocked by sunscreen, meaning that sunscreen
has
only a small impact on the rate of synthesis. Secondly, many foods
(i.e.
dairy products) have high levels of the "fixed" form of VitD already
(and
some have extra added during processing), so you can get it from your
diet.
The second point worth making is that the recently reported advantages
of
high VitD intake are controversial - only a few studies have identified
the supposed benefits, and the levels of VitD where those benefits were
observed are close to levels where VitD becomes toxic (and are far above
normal intakes). So until additional studies, including those looking
for
long-term consequences, are undertaken, those studies seeing advantages
to
high vitD intake should be taken with a grain of salt.
The final point worth making is that the link between excessive UV
exposure and melanoma is well established and unquestioned. The form of
skin cancer caused by UV exposure (melanoma) is also one of the most
lethal cancers out there. So if you're worried about VitD, take a VitD
supplement and slap on the sunscreen. Because the potential benefits of
high VitD are far, far, far outweighed by the risks of melanoma.

Do you realize that one of the most powerful cures for cancer is streaming
over our heads each and every day, free of charge? It's sunlight, which is
astounding in its ability to prevent and cure cancer. If it were a
mainstream drug, it would probably make the cover of Time magazine and be
heralded as the greatest medical breakthrough in the history of modern
science. It's that good.
Sunlight exposure reduces the risk of many cancers by more than 50 percent
and even helps reverse certain types of cancers through the creation of
vitamin D in the body. It's a magnificent natural healing modality, and
it's
been right in front of our eyes, every single day, since before Homo
sapiens
even evolved on this planet. Yet somehow, after spending billions of
dollars
on so-called medical research to find "cures" for various cancers, almost
no
one from the world of mainstream medicine has yet acknowledged the healing
power of natural sunlight and vitamin D.
None of them have actually prescribed sunlight to patients, except for
perhaps a handful of pioneering researchers like Dr. Michael Holick, who
was
attacked for speaking out about the truth of sunlight and cancer. By and
large, the medical community has not only ignored this truly miraculous
cure
for many types of cancer; it has worked hard to discredit it.
If there were ever a reason to lose faith in conventional medicine, or
so-called modern medicine, it is simply the fact that one of the greatest
cures and prevention strategies for cancer goes completely ignored by
nearly
the entire conventional medical community. It's as if there were a miracle
medicine invented, but conventional medical doctors didn't want anyone to
find out about it. Why aren't researchers promoting cures that are
available
for free?
Protecting the medical dogma
The medical community doesn't want to promote cures it did not invent.
When
nature offers a cure, that's not very satisfying to the egos of drug
company
researchers and scientists. A drug company only wants to promote cures
that
it can patent and exploit for financial gain. The way it perpetuates the
cycle is to make sure that the cancer treatments it controls get a lot
more
press and hype than any natural treatments. You don't see sunlight
promoted
in full-page advertisements for its ability to prevent or reverse cancer.
Instead, the medical community uses the full-page advertisement for
high-profit prescription drugs that have negative side effects and
actually
kill people.
