Vitamin D reduces
inflammation, improves prostate cancer in 60% of men by: David Gutierrez
(NaturalNews) Doses of vitamin D equivalent to
those from daily sun exposure were able to slow and even cure low-grade
prostate cancer in a new study conducted by researchers from the Medical
University of South Carolina.
"We're treating
these guys with normal body levels of vitamin D," lead researcher Bruce Hollis said.
"We haven't even moved into the pharmacological levels yet."
Vitamin D,
which plays an important role in bone and immune health, is produced by the
body upon exposure to ultraviolet radiation from sunlight. Prior studies have
suggested that it may help prevent or even treat prostate cancer. For example,
an earlier study by the same researchers found that, among men with low-grade
prostate cancer who took a vitamin D supplement for one year, 55 percent had
their cancers become less aggressive. Some of the tumors even disappeared.
Tumors shrank and
vanished
Research has
shown that many prostate cancers either cure themselves or are so slow-growing
that they are unlikely to ever become dangerous. In contrast, aggressive
prostate cancer can be highly lethal.
Their new study was conducted on 37 men with low-grade (non-aggressive)
prostate cancer who were undergoing elective prostate removal. During the
60-day waiting period, the men were randomly assigned to take either a vitamin
D supplement (4,000 international units) or a placebo pill. After surgical
removal, all the prostate glands were examined.
The researchers found that the prostate cancer in men given a placebo
was either unchanged or had worsened. The opposite was found in the vitamin D
group.
"In greater than 60
percent of those taking it, vitamin D actually made the cancer better," Hollis said. Some of the tumors shrank, while some
actually vanished completely. In
addition, the researchers found that levels of certain key lipids and proteins
were also lowered in the vitamin D group, indicating less inflammation.
The anti-cancer
vitamin
Further
research will be needed to uncover the links between vitamin D and prostate
cancer. The researchers are working on a larger trial.
"We don't know yet
whether vitamin D treats or prevents prostate cancer," Hollis said.
"At the minimum, what it may do is keep lower-grade prostate cancers from
going ballistic."
However
limited, the study adds to a growing body of research linking vitamin D to
reduced cancer mortality. Indeed, as far back as 2008, a study
published in the Proceedings of the National Academy of Sciences concluded that
if everybody doubled their sunlight exposure, 10 times more lives would be
saved from cancer prevention than would be lost to increased fatal skin
cancers. Health experts recommend that
light-skinned people in temperate climates get at least 15 minutes of
unprotected daily sun exposure on the face and hands. People with darker skin
might need two or three times as much; exposure
should also increase with distance from the equator.
