High
Dosage Vitamins Increase Cancer Risk... when they're synthetic
vitamins
Even though my own product, The Pilot’s
Super Supplement, delivers concentrated doses of vitamins—among
other nutrients—I am constantly warning my customers, friends
and relatives about the dangers of high dosage vitamins. And with
good reason.
A new study has just been published stating
that, “taking too many [vitamins] may increase men’s
risk of dying from prostate cancer.” We could not agree
more with this statement. The study published in the Journal of
the National Cancer Institute followed the overall health and
diets of 300,000 men. The study concluded that “heavy multivitamin
users were almost twice as likely to get fatal prostate cancer
as men who never took the pills”.
There was a small catch in the researchers’
findings. There was no link found between vitamin use and early
stages of prostate cancer. “The researchers speculated that
perhaps high-dose vitamins had little effect until a tumor appeared,
and then could spur its growth.”1
Taking a multivitamin may actually increase
the growth of tumors? What is wrong with this picture? Taking
a daily vitamin should promote health within the body. The problem
arises when people are consuming synthetic vitamins. The majority
of all vitamins sold in stores today are synthetic. This means
they are created in a laboratory. For example, Vitamin C is commonly
sold as ascorbic acid. Ascorbic acid is made by combining corn
syrup and hydrochloric acid. In fact, most vitamins in supplements
are petroleum extracts, coal tar derivatives, and chemically processed
sugar (plus sometimes industrially processed fish oils). Other
acids and industrial chemicals (such as formaldehyde) are used
to process them.2-5 Does that sound like it would be good for
the body?
There was even a study published in the Los
Angeles Times that illustrated how synthetic ascorbic acid (sold
as vitamin c) gave participants 2.5 times thicker arterial walls,
thus increasing their risk of heart disease. Another study published
in the Canadian Medical Association Journal found that taking
megadoses of vitamin C (ascorbic acid) can cause rebound scurvy;
strange considering scurvy is a deficiency in Vitamin C. There
is study after study that prove synthetic vitamins are not only
not good for your health, but can actually be detrimental!
The British Heart Protection study tracked a
large number of adults for 5 years. They found that people who
regularly take antioxidants (vitamins A, C, and E) had no reduction
in heart attacks, strokes, cancer, or diabetes. The researchers
speculate that people may get more benefit from getting their
daily requirement of vitamins from fruits and vegetables instead
of a pill. In fact, each increment of 3 daily servings of fruits
and vegetables equates to a 22% decrease in the risk of stroke.6
It would be difficult for even the healthiest
individuals to get their entire daily allotment of all vitamins
and minerals from foods. Many foods do not contain the vitamin
content they once did. This is due to soil depletion, current
farming methods, and methods of food production and preparation.7
There is an alternative to make sure one is meeting their daily
requirement of vitamins: whole food vitamins—vitamins that
are obtained directly from the foods!
The body is built to easily recognize and utilize
whole food vitamins. There are vitamins available on the market
today that show only whole food sources. For example: Vitamin
C listing oranges, broccoli, black currants, and acerola cherries
as the main ingredients. This ensures the vitamin is in the form
nature intended, from food.
Has there ever been a study showing the negative
side effects from the Vitamin C consumed from oranges or the Vitamin
A consumed from carrots? They do not exist. The problems only
arise when the consumer is taking a synthetic version of the vitamin.
The Journal of the American Medical Association reports that every
American needs to take a multi-vitamin.8
In addition to the need for all-natural whole
food vitamins, there are other nutrients that are shown to promote
healing within the body. When it comes to most any disease—even
prostate cancer—certain nutrients can help the body to heal
itself.
In the Townsend letter for medical doctors a
study done with saw palmetto, which is extracted from a type of
palm tree, has been shown to prevent the conversion of testosterone
to DHT, and to reduce prostate symptoms in clinical tests.9
Another study found that men consuming the most
dietary selenium (whole food based selenium) developed 65% fewer
cases of advanced prostate cancer than did men with the lowest
levels of selenium intake.10
Other nutrients that have been proven to help
with prostate health include: zinc11, lycopene12, vitamin E13,
pygeum14, stinging nettle15, omega-3 fatty acids16, and proteolytic
enzymes17.
The body has the ability to heal itself. It
just needs to be given the proper nutrients. The body is an amazing
device that wants to be healthy. If given the right nutrients
the body has its own tremendous healing powers. It is easy to
create more deficiencies or problems by taking the wrong kind
of nutritional supplements. Make sure to read the labels on any
products considered and as a good rule of thumb, if the ingredients
are all chemical names (or unpronounceable) it would be wise to
stay away.
