Sunshine helps to fight cancer
Washington, Feb 17: Vitamin D dubbed ''the sunshine vitamin'' could become a useful weapon in the fight against one of the most devastating diseases of our time, cancer, a new reasearch says. Researchers say Vitamin D could block the development of some cancers, strengthen bones, prevent multiple sclerosis and alleviate winter depression.
"As time has gone by, Vitamin D has raised its head as a sort of ambrosia for cancers," says Dr Louise Parker, an epidemiologist and a world expert in the environmental exposures that can lead to cancer."One of the most important sources of Vitamin D is from the sun and through your skin," she adds. "On the average, 1,000 units a day is safe and is probably effective in reducing the risk of colon cancer, and maybe other cancers as well,'' The Science Daily quoted Dr Parker as saying. She says 1,000 units a day is well beyond what you can obtain from your diet. Vitamin D is a bit of a rare vitamin, appearing only in fatty fish, cod liver oil and egg yolks. Even if you were to sunbathe in southern climates, you would not take in 1,000 units.
She notes Vitamin D as a factor is turning up in study after study. It turns out people with lung and colon cancer are Vitamin D deficient. And it helps the body absorb calcium. In a study examining whether women who took Vitamin D had a lower risk of osteoporosis, it was found the women taking Vitamin D had stronger bones than those who did not take the vitamin. Years later, researchers went back to that study and found that the women who took Vitamin D also had fewer cancers.
However,
more
research
needs
to
be
carried
out
in
this
regard.
Vitamin
D
works
in
very
complicated
ways,
she
says.
It
changes
the
way
cells
work.
In
fact,
there
is
medical
speculation
that
it
may
block
cancer
cell
proliferation
or
improve
immune
system
functions.
But
its
role
is
not
fully
understood.
Meanwhile,
there
is
very
little
evidence
that
taking
Vitamin
D
can
harm
you.
Perhaps
in
huge
doses
it
could
cause
kidney
stones,
but
that
has
not
been
proven,
she
adds.
