Fish Oil Study Related To Prostate Cancer A Scam

One poorly designed study on low dose OTC items irrelevant to products like Amarin, and actually all fish oils. The dosing alone shows that the effect was not directly related to fish oil. Further, plant sources have the same molecular DHA/EPA structure as fish, yet researchers suggested plant sources did not produce same effect. This deems the study completely irrelevant. Further, EPA not cited as suspect agent.

CRN SAYS NEW STUDY ON
OMEGA-3 CONCLUSIONS ARE OVERBLOWN

WASHINGTON, D.C., July 11, 2013-In response to a new study, "Plasma Phospholipid Fatty Acids and Prostate Cancer Risk in the SELECT Trial," published yesterday online in the Journal of the National Cancer Institute, the Council for Responsible Nutrition (CRN), the leading trade association representing the dietary supplement industry, today issued the following statement:
Statement by Duffy MacKay, N.D., vice president, scientific and regulatory affairs, CRN:

"The numerous benefits of omega-3 fatty acids from foods (like salmon and sardines) and dietary supplements are well-established for men and women in all stages of life-and this new study does not change those recommendations about the importance of this nutrient. Hundreds of studies over the past two decades have shown omega-3 fatty acids to have positive effects associated with cardiovascular health, perinatal health, inflammation, cognitive function, or cancer. Collectively, this body of research serves as the basis for numerous recommendations from respected organizations, scientific boards and healthcare practitioners that Americans get omega-3 fatty acids in their diets.

While we encourage researchers to continue to study omega-3 fatty acids with an open mind, it is counterproductive when studying nutrition for researchers to promote their study as if it were the only piece of research that counts. In this case in particular, it is especially disingenuous for the researchers to make the kinds of assertions we've seen in the press, given their results are in stark contrast to previous epidemiologic studies1 that not only demonstrate no correlation between omega-3 consumption through fish and/or supplementation and the risk of prostate cancer, but in many cases also showed a protective effect against prostate cancer.

Further, the researchers were quick to blame dietary supplements even though there is no evidence that anybody in this study took fish oil dietary supplements. In fact, the study demonstrates no cause and effect; it can only purport to show an association between higher plasma levels of omega-3 fatty acids and those whom the researchers advise had an increased rate of prostate cancer.

One should also consider whether this study could have simply been measuring a biomarker reflecting recent intake of fish or fish oil supplements in a group of high risk cancer patients that had been told to increase their EPA and DHA levels, as compared to a group of non-cancer patients that had not been told to consume more EPA and DHA. Plasma levels of EPA and DHA reflect very recent intake and are considered a poor biomarker of long term omega-3 intake especially when compared to red blood cell levels, which reflect medium term intake. A single fish oil dose (or hearty serving of fish at lunch) results in >100 percent increase in plasma omega-3 levels. So looking at plasma levels in healthy and sick people may only provide insight into the recent habits of these individuals.

Additionally, the study's conclusions are also limited by the fact that the study was not designed to evaluate the question the researchers sought to confirm.

The American Heart Association, the World Health Organization (WHO), the U.S. Institute of Medicine's Food Nutrition Board (IOM FNB) and the 2010 Dietary Guidelines all have current policies advising Americans to eat more fatty fish to get the benefits of omega-3 fish oils. It is highly unlikely this one study will change that advice. Omega-3s can also be obtained by taking one of the many supplement products on the market. For those consumers who have concerns about prostate cancer or other questions about omega-3 fatty acids, we recommend speaking with your doctor or other healthcare practitioner."
