Fred Schwartz - 21 Jan 2007 04:49 GMT Is there any evidence that omega-3, 6 or 9 or flax can be helpful in thwarting cancer of the prostate? Is there any reason not to supplement with these oils?
Thanks, Fred

As to flax, it contains alpha-linolenic acid as the omega-3. While not as bad as alpha-linoleic acid (omega-6), at least one study has shown that it too stimulates PCa cell growth. Still, with flaxseeds, their is enough good "stuff" in them that ground seeds are considered to be acceptable by some, while all agree that the oil is to be avoided.
Here is a link that may prove helpful. The first link
http://cancer.ucsf.edu/crc/nutrition.php
takes you to a UCSF website. Once there, click on "Nutrition and Prostate Cancer" to download a PDF file on nutrition and PCa. It covers omega-3, 6 and flax, as well as diet, supplements, herbs, etc. It even provides some recipes!
Here is a copy of the article on flaxseed...Best wishes and good health, ron
Flaxseed oil supplement may be harmful to men By WILLIAM P. MARLEY - guest column Flaxseed nutritional supplements have some positive health benefits. Recent research has shown, for example, that they may help prevent heart disease and breast cancer. We no longer recommend flaxseed oil to our male patients in the Diabetes Exercise Center and Cardiac Rehabilitation Program, however, because current medical opinion has related these supplements to prostate cancer. Dr. Dean Ornish's research first demonstrated that heart disease can be reversed with therapeutic lifestyle changes such as exercise, sensible nutrition, smoke cessation and meditation. I asked him about evidence that indicates flaxseed oil may promote the growth of prostate tumors. Does flaxseed oil cause prostate cancer, or does it stimulate the growth of existing prostate cancer cells? Also, does this warning apply to ground flaxseed meal? "The omega-3 fatty acids can be highly protective against heart disease," Ornish responded. "Flaxseed oil and fish oil are two concentrated sources of omega-3 fatty acids. However, some scientific evidence has caused me concern about recommending flaxseed oil because it may accelerate the progression of prostate cancer. Fish oil, in contrast, does not seem to have this harmful effect on prostate cancer." Flaxseed oil is a rich source of alpha-linolenic acid, which has been shown to be beneficial in both heart disease and breast cancer. According to Dr. Charles E. Myers Jr., however, a scientist at the University of Virginia Medical School in Charlottesville, available research suggests that alpha-linolenic acid may be dangerous for prostate cancer patients. "Five out of six studies found an increase in the risk of prostate cancer associated with alpha-linolenic acid," Myers said. "Our laboratory, as well as others, found that alpha-linolenic acid is one of the most powerful growth stimuli for human prostate cancer cells." After reviewing Myers' findings, Ornish commented further. "Thus, I now recommend fish oil, rather than flaxseed oil, for men and either for women. The same applies to flaxseed meal as well as the oil, although flaxseed contains a number of phytochemicals, such as lignans, that are of potential value. One of the major lignans in flaxseed is secoisolariciresinol, a phytoestrogen and antioxidant. "However, you can get these phytoestrogens in other foods, such as soy, without the potential problems of flaxseed and flaxseed oil." Always consider food and vitamin supplementation carefully. Before beginning any new nutritional regimen, discuss it with your physician to be informed of any potentially harmful side effects. William P. Marley, Ph.D., is a professor and director of the Human Performance Laboratory at Marshall University. You can e-mail him at marley@marshall.edu.

Long, excruciatingly detailed, well-documented debates among experts over at sci.med.diseases.cancer disagreed on the impact of walnuts on PC, but agreed strongly that flaxseed will promote PC growth. I gave my flaxseed oil capsules to my wife and reduced my walnut consumption. Google that forum for discussions of omegas, flax, etc. and key in to discussions involving Matti Narkia.

> Is there any evidence that omega-3, 6 or 9 or flax can be helpful in > thwarting cancer of the prostate? Is there any reason not to > supplement with these oils? > > Thanks, > Fred Theralogix makes a fish-oil supplement called TherOmega, which I would look into. I highly recommend Theralogix products because I have been reviewing this company pretty extensively in recent days. (See my comments on "Health Food Trauma, thread.) This co. focuses exclusively on urology-related products (also, bladder, UTI supps.). Theralogix has a panel of very distinguished and highly qualified doctors who consult about what goes into their products, and the company also seems to have very high quality standards. Here's a sample from the Theralogix website: (Theralogix.com)
TherOmegaTM is a natural source of omega-3 fatty acids derived from pharmaceutical-grade fish oil. This supplement has been independently tested and certified for content accuracy and purity (by NSF? International) and for freedom from contaminants such as mercury, lead, and PCBs (by the International Fish Oil Standards Program). TherOmegaTM is the only fish oil supplement that has been tested and certified by both of these organizations. TherOmegaTM contains the following ingredients:
Omega-3 Fish Oil 550 mg EPA 350 mg DHA 200 mg
60 day supply: $25.
Also, if you go to their site and click on "medical journal articles" you will be linked to the latest research pertaining to the subject you're interested in. So have a look. Anyway, this is from their site (abridged).
1: Cancer Causes Control. 2006 Mar;17(2):199-208.
Diet after diagnosis and the risk of prostate cancer progression, recurrence, and death (United States).
Chan JM, Holick CN, Leitzmann MF, Rimm EB, Willett WC, Stampfer MJ, Giovannucci EL. Department of Epidemiology, University of California, Room A622, San Francisco, CA, 94143-1695, USA. june@uorg.ucsf.edu
OBJECTIVES: We examined post-diagnostic diet and risk of cancer progression in a cohort of men with prostate cancer from the Health Professionals Follow-up Study. CONCLUSIONS: These data suggest that diet after diagnosis may influence the clinical course of prostate cancer, and fish and tomato sauce may offer some protection against disease progression.
Also: Someone from this group had referred me to another company that I was impressed with, so I want to pass it on. Brownwood Acres, a family-run business which primarily sells fruit from local orchards, seems to offer a very high-quality fish oil supp. as well. (Look under "supplements.") This is from BA website:
Wild Alaskan Sockeye Salmon Oil Capsules
These pharmaceutical grade fish oil capsules contain ONLY pure Wild Alaskan Sockeye Salmon Oil. Each 1000 mg softgel provides approximately 260 mg of total omega-3 fatty acids, including 150 mg of EPA and DHA. In addition, laboratory analysis reveals an amazing 32 distinct additional fatty acid molecules you're unlikely to find in highly processed "purified" alternatives. Truly a unique health-promoting product. Purity and potency guaranteed.
Price is $35 for three mos. That sounds reasonable.
I don't know which of the above products is better, but maybe someone else does.
BTW, Brownwood Acres also sells locally grown pom products, such as pom concertrate capsules and even fruit bars.

Richbro - 23 Jan 2007 01:31 GMT My only suspicion of Theralogix is that they have a nice little kick-back incentive with Doctors. Doesn't make them right or wrong, just makes me wonder. They also claim to be conducting a clinical trial on their "Prostate 2.2" supplement (which used to cost $60/2 mo. supply, now $70/2 mo. supply). I could not find the trial using my own research. I'm now buying the equivalent of Prostate 2.2 at half the cost by combining 2 other supplement packages. Just raising questions ... , if their product is really better, I'd switch back.

Doesn't make them right or wrong, [quoted text clipped - 4 lines] > > Rich-- I don't work for Theralogix, but I can tell you this: According to their website, "financial info" section, they do not pay *any* commissions to doctors. That doesn't mean they can't compensate the docs in some other way, but that's something else. I feel comfortable with their supplements precisely because they were not recommended by any MD.
I haven't seen anything on the Theralogix website about a research study, but if you want info about that you can just email them.
If you are comfortable with your current regimen there's no reason to change. In my case, if I bought the 5 components of the supp, separately (in a local store), it would cost me more than $35/month.

Richbro - 24 Jan 2007 23:32 GMT Leah, thanks. My uro told me about Theralogix and gave me a code to type in when ordering. It seemed obvious to me, but maybe it's all OK. I took their product for over 2 years and then started pinching pennys.
The clinical trial information was in a flyer from Therlogix with one of their shipments. I was trying to verify from an independent source. I'll look up the info. if you're interested (on the trial).

Just came across this on acor ml. Dr. Myers has a lot of followers.
Ralph,
For fish oil, Dr Myers recommends Nordic Naturals.

Is there any reason not to [quoted text clipped - 10 lines] > > leah Fred Schwartz - 28 Jan 2007 18:26 GMT I tried to find a website that would permit you to track the amount of Omega-3 you are eating. I found www.calorie-count.com and that does not include the oils. I tried www.nutritiondata.com and that database is incomplete. For instance, I could not find the Back-to-nature breakfast cereal that I eat every morning. Prior to making significant changes to my diet, I want to assess where I am starting. Has anyone been able to find a site that will give you the information that may be valuable to people with PCa and store it in a database without inputting the data by hand?
Thanks, Fred
