Fish oil study about prostate cancer risk misleading?

Some experts are not convinced the new fish oil study shows cause and effect. While researchers suggest a link between prostate cancer and Omega 3 fatty acid oils from supplements and oily fish like salmon, other medical experts say the new fish oil study is "incomplete" and leaves out many other cancer-causing risk factors.

A July 11 Healthland report via Time Magazine, shared findings from the controversial study that has caused ripples on the Internet.

Essentially, the study published in the Journal Of The National Cancer Institute says that men who consumed high levels of marine fish like salmon and/or fish oil supplements, run the risk of a 43 percent increase in prostate cancer. Additionally, there is a 71 percent increase in the deadly type.

One of the biggest drawbacks of this study is that it is retrospective. In other words, it looks back at old data. Additionally, it did not query participants about their dietary habits.

A Huffington Post report in March of 2011 suggested Omega 3 fatty acids from all sources reduce the risk of prostate cancers in men.

It read in part:

"Research has uncovered evidence that ALA from foods such as flaxseed, egg yolks, and canola oil may increase the growth and spread of prostate cancer. In a Harvard School of Public Health study that included more than 40,000 men followed for 10 years, the investigators found that ALA consumption increased the risk of advanced prostate cancer while omega-3s from fish reduced the risk."

Dr. Geo Espinosa, a respected naturopathic doctor and acupuncturist with a specialty in prostate disorders, suggests something is "fishy" about the 2013 fish oil study.

He points to several other studies that support protective benefits from Omega 3 fatty acid studies.

A few are:

"Researchers investigated the effect of dietary fish intake amongst 6272 Swedish men who were followed-up for 30 years. That study reported that men who ate no fish had a two?three-fold increase in the risk of developing prostate cancer compared with those who consumed large amounts of fish in their diet."

"Another prospective cohort study based on the Physician?s Health Study found that fish consumption (?5 times per week) was not related to prostate cancer risk but was protective of prostate cancer?specific death."

"Other studies have suggested lower prostate cancer risk with Omega 3 fatty acids from fish in Swedish men (Norrish AE, et al.) and in Japanese and Brazilian men."

Mike Adams, aka the Health Ranger from Natural News, characterizes the new study on fish oil and prostate cancer risk "quackity quack."

Adams, a longtime practitioner of natural health, says that readers should take the study with a grain of salt. Furthermore, lists several ways in which Big Pharma can fake a study to skew results in its favor, with profit as a driver.

While the new fish oil research suggests a link of prostate cancer heightened risk with consumption of Omega 3 fatty acids, more research needs to be conducted to rule out other possible causes.
