There has recently
been a rumour that flax oil can cause prostate cancer or
inflammation and it has had many people in a tizz. So I have spent
some hours investigating where this rumour started and it seems to
come from a ‘doctor’ Newstaedter, who calls himself a doctor of
homeopathy, acupuncture and oriental medicine. Without going into
his philosophy and health guidelines which are a bit wonky any way,
I find the photo of him appears to indicate that he is battling with
his health. He seems to be suffering from a skin problem and has
dark rings under his eyes; assuming that most people would put their
best picture on the web, this is a bit alarming;
a man clearly in ill
health dispensing health information? I should not be too shocked as
this seems to be the norm. Overweight people write best sellers on
weight and health regularly. What amazes me is that people actually
give these ‘gurus’ money for their advice and products and buy
their wares.
There are only 13
references to ‘flax and prostate’ on the Google search engine
and 2-3 that contain a reference to flax causing prostate problems
lead back to the above doctor. Most of the other references actually
offer extensive research where flax oil has been proven to reduce or
prevent cancer in many forms including of the prostate.
One
refererence mentions Dr Dean Ornish, but
you can check out his website he actually prescribes 1
gram of flax oil daily.
So my conclusion on
this is that someone somewhere wants to upset the huge flax market
and promote fish oil products, either because they have vested
interest in fish oil products, are simply ignorant or have some
other motivation. The internet can be
confusing as often people promote themselves with qualifications or
quote information that is conflicting. I have found that it is
important to dig deeper and find the truth. The internet is a great
place to do research as long as you check out all aspects of the
issue you are researching and check out the credentials and
lifestyle of the site owner. We may often take information from a
‘doctor’ assuming that because of their qualifications they own
the right to knowledge, but surely the correct pedigree for
information would be yes training and studies but also unsurpassed
health?
So is there any
truth in this rumour? I would say categorically not! Unless of
course the flax oil they are using is not guaranteed organic, cold
pressed, freshly extracted, nitrogen flushed and bottled in
fluoridated bottles. Fluoridated bottles prevent xenoestrogens from
the plastic being leached into the oil. Bottling in any type of
plastic could result in this happening and these xenoestrogens are
carcinogenic. This means they encourage growth of cancer cells in
any part of the body including the prostate.
If the flax oil is
not Nitrogen flushed (which dispels oxygen keeping the oil fresh)
the oil becomes rancid easily and rancid oil of any kind is
carcinogenic.If flax oil is heated above 38oC it can also become
carcinogenic
Using organic flax
seed from which to press the oil also means that there is no risk of
you being exposed to toxic pesticide and fertilizer residues. The
only Flax oil that I can categorically state that complies with all
these issues i.e. guaranteed cold pressed not above 38oC, nitrogen
flushed, pressed from organic seed and packed in a fluoridated
bottle is Millbrook flax oil and the Aim
blend Aimega (which
is blended with Millbrook Flax oil)
Yes you may be able
to buy a cheaper oil, but at what price to your health. Flax oil is
extremely beneficial to you health, just make sure it is the right
stuff! One of the reasons that fish oil is promoted by some is
because of the beneficial effect on our health of EPA (eicosapentaenoic
acid) and DHA (docosahexanoic acid). These are fatty acids which are
made in our bodies from the essential
fatty acid
Linolenic acid also known as alpha Linolenic acid or Omega 3. This
is a normal metabolic pathway that takes place in the body unless
you are one of maybe 2% of people who lack the ability to do this.
We know that the body makes natural cortisone which is essential for
our bodies to function correctly, yet cortisone taken from another
source in medication has some serious side effects. This could be
the case too with taking in fish oil as a supplement as you are not
allowing the body to make the EPA and DHA, which it is designed to
do.
When you take EPA
and DHA from a fish oil sources you are by passing this metabolic
pathway and no research appears to have been done that indicates
what the long term effect is on humans. It makes no sense to buy a
substance that is made by the body for free.
Surely if we are
meant to do that we would be best off eating human organs like the
adrenal glands which are exceptionally high in these two fatty acids
(DHA and EPA).Besides which fish oils are processed by mincing the
whole fish and then extracting the oil with chemical solvents and
heat. This will create carcinogenic substances and on top of that
when you buy these products they are encapsulated and there is no
way of knowing whether they are still fresh or rancid.
Then flax oil has
been prescribed for prostate problems for hundreds of years, I have
personally seen how flax oil has benefited thousands of people and
dozens with prostate problems. Flax oil has been used to promote
health as far back as 650BC.
Hippocrates in the 5th century mentioned flax to relieve
inflamed mucous membranes and for abdominal relief. Flax oil
has a history and pedigree unsurpassed by any fish oils. (see
separate info on Benefits of flax oil)
My family and I
including my 3 daughters and 2 year old grandson and husband Mark
will continue using Millbrook flax oil as we have for many years. We
know that The Natural Way diet, Barleylife
and flax oil have resulted in unprecedented health
for us as a family
(no medical bill due to illness in nearly 20 years)
From the internet
I used to grind flax seed in a coffee grinder and sprinkle about 2 tablespoons onto my cereal in the morning. I enjoyed its nutty flavour and also the fact that it may be the best vegetarian source of omega 3 oil. I preferred ground flax seed to the oil
for its phytochemicals and fiber. I kept a few days supply of ground seed in the freezer.
I heard recently that Dean Ornish has stopped recommending flax or its oil to men and claims that he never did (not true) and that he always recommended fish oil or eating fatty fish. He now states that the reason he does not recommend flax
seed is due to work done by a researcher at the University of Virginia Medical School, which indicated that when cancer cells are present in the prostate, flax can make them more aggressive and increased the likelihood of prostate cancer considerably.
I did a computer-assisted search at U of Virginia Med School Library and was not able to find any info on flax and prostate cancer.
This was on one of the sites listed, so I checked out Dr Ornish’s site and he recommends both flax oil capsules (1 gram daily to be exact) and fish oil (seems he wants you to take anything that may be going on the market) So this is clearly just a
rumour started by some vindictive fish oil selling opposition and this person is clearly confused.

NEW PILOT STUDY SUGGESTS FLAXSEED AND
LOW-FAT DIET CAN BE PROTECTIVE AGAINST PROSTATE CANCER
Note to editors: Wendy Demark-Wahnefried

DURHAM,
N.C.--A low-fat diet supplemented with
flaxseed may help reduce the risk of prostate cancer,
researchers from
Duke
University Medical
Center report in the July issue of
Urology.
The researchers said dietary fat and fiber can affect
hormone levels and may influence cancer progression.
Flaxseed is high in fiber and is the richest source of
plant-based, omega-3 fatty acids. Studies suggest that
dietary fiber reduces cancer risk, and omega-3 fatty
acids also have shown a protective benefit against
cancer. Flaxseed is also a rich source of lignan, a
specific family of fiber-related compounds that appear
to play a key role in influencing both estrogen and
androgen metabolism.
"We thought flaxseed would be the perfect food for
prostate cancer patients," said lead author Wendy
Demark-Wahnefried, associate
research professor in the department of surgery at Duke.
"It's full of omega-3 fatty acids, fiber and lignan.
Testosterone may be important in the progression of
prostate cancer, and lignan in the flaxseed binds
testosterone, so we thought the flaxseed might suppress
the growth of prostate cancer cells. By pairing a
low-fat diet with the flaxseed supplement, we also
thought we could maximize the effect of the omega-3
fatty acids, since studies in animals show that the kind
of fat we eat may be important for cancer progression."
The pilot study involved 25 patients with prostate
cancer who were awaiting prostatectomy (surgical removal
of the prostate). Baseline levels of prostate-specific
antigen (PSA), testosterone, free androgen index and
total serum cholesterol were determined at the beginning
of the study. The tumors of those on the diet were then
matched with 25 historic cases, equal in age, race, PSA
level at diagnosis and biopsy Gleason sum (a scoring
system used to grade prostate tumors) to compare tumor
progression and biomarkers after the dietary
intervention.
The men were on the low-fat, flaxseed-supplemented diet
for an average of 34 days. Finely ground flaxseed was
used in the study because, in its natural form, flaxseed
is a pointy, tough seed that can puncture the intestines
when consumed in the amounts used in this study (three
rounded tablespoons a day). The ground flaxseed in the
study was vacuum-packed (ground flaxseed can quickly go
rancid) and had added emulsifiers for ease of mixing.
The men were instructed to sprinkle the flaxseed on
their cereal or mix it into juices, yogurt or
applesauce. Researchers reported good compliance with
the diet and said it was tolerated well.
At the end of the study, the researchers observed that
the men on the diet had significant decreases in
cholesterol, and both total and free testosterone. While
there was a decrease in testosterone levels, they noted
that none of the participants in the study suffered
decreased libido or sexual dysfunction. There was a
trend toward a decrease in PSA levels in men with
early-stage prostate cancer (Gleason sums of six or
less), but in men with advanced prostate cancer (Gleason
sums of more than six) PSA levels continued to rise.
"It's not surprising that a diet therapy that was only
taken for an average of 34 days had little effect on men
with aggressive disease," Demark-Wahnefried
said. "But what we did see was that for the men on the
diet, their tumor cells did not divide as quickly and
there was a greater rate of apoptosis (tumor cell death)
in this group."
With such a short-term dietary intervention, the
researchers said they did not expect to see a difference
in tumor biology between the diet-treated patients and
the control patients, but were encouraged by the lower
proliferation rates and significantly higher rates of
apoptotic cell death. However, they said the results
should be interpreted with caution, stressing that
randomized controlled clinical trials are needed to
confirm the results of the pilot study. Research on mice
models is currently under way, and preliminary results
support the findings in humans.

A staggering 10.3 million new cases of cancer are
diagnosed each year worldwide, making cancer a top public health
priority. The right diet can be a powerful weapon against the
development of this potentially deadly disease. Expert reports
indicate that diet changes alone may prevent 30 to 40%, or
3 to 4
million cases a year.
Studies conducted by Dr. Stephen Cunnane
of the
University
of
Toronto
showed that flax prevents the growth of new cancer cells. According
to Dr. James Duke of the
U.S.
Department of Agriculture, flaxseed contains 27 identifiable cancer
preventive compounds.
Recent studies show that Omega-3 oils found in flax (linolenic
acid) may kill human cancer cells in tissue culture without harming
the normal cells. Breast, lung and prostate cancer cell lines were
studied.
Lignans are plant compounds called
phytoestrogens that act like a weak form
of estrogen in humans. It has been well established that populations
with high fiber diets and high intakes of
phytoestrogens such as lignans,
tend to have lower rates of hormone-dependant cancers, such as
breast, endometrial and prostate cancers.1
Research evidence suggests that lignans
may fight off chemicals responsible for initiating tumors and block
estrogen receptors, which may reduce colon cancer risk. According to
the research of Dr. Lillian Thompson of the University of Toronto,
flaxseeds are the richest source of plant
lignans and contain 75 to 800 times more than wheat bran,
oats, millet, rye, legumes, soybeans and 66 other plant foods
tested.2
At the December 2000 San Antonio Breast Cancer Symposium, Professors
Lillian Thompson, from the University of Toronto, and Paul Goss,
from Princess Margaret Hospital in Toronto, stated "for the first
time, it has been shown that flaxseed has considerable potential in
reducing tumor growth in humans with breast cancer comparable to the
effects seen with preoperative Tamoxifen."
3
Studies conducted by COSC's Research and
Development team showed that carefully monitored germination of
flaxseed significantly enhanced the mammalian lignan content found
in ungerminated flaxseed.
Some studies have shown that beta-carotene may be an effective ally
against prostate cancer. A recent study found men with the lowest
level of beta-carotene in their blood were at the greatest risk of
developing this cancer.
This is a
reply from one doctors site (Dr Stoll, a medical doctor) when asked
about the rumour that flax can cause some problems
JT, I believe where this info is
coming from is tainted or spoiled flax oil. This I have read and
believe to be true. But in my opinion and everything I have read
good flax oil is going to do nothing but help you. I have had
nothing but good results from it and have taken it for years. Most
men that I know who have taken it for awhile there prostrate
problems have all but disappeared. Flax oil does spoil and it needs
to be frozen until you start using it. I have never taken capsules
of flax oil because of this reason. Hope this helps some. Good luck
I would like to see any research
that shows this when care is taken to assure freshness. ANY
rancidity of ANY oil is a cancer risk.
