A little running in place mixed with up downs is a great way to start any warm-up, see all smiles.

Below is an article posted on the Stronger Faster Healthier Blog in response to a study that came out linking fish oil to prostate cancer.  Let us know your thoughts in the comments.  

HERE is the original study that started the discussion with many experts weighing in.  

Why experts in the science and medical fields conclude that the study linking omega 3 fatty acids and prostate cancer makes NO valid conclusions:
After research, several science and medical professions indicated that the studies correlating omega 3 supplementation to prostate cancer are biased. The conclusions found are based on a correlation study not a causation study, virtually meaningless. Review the response posted by professionals, At Nutra Ingredients USA.

The “research” is nothing more than a retrospective epidemiological study on long chain fattyacids. The abstract being reviewed looked at a population of men who were diagnosed with prostate cancer, then compared them to a group of men who did not have prostate cancer. The data collected from all participants was a serum omega-3 fatty acid percentage; the researchers then split the groups into quartiles to identify if there was any association.
“Fish oil causes cancer” is an inaccurate statement that was derived from data and skewed with inter-study variability. A further statement that could have been made was “persons with prostate cancer showed higher concentrations of n3 in their blood.” Anti-inflammatory therapy, such as a high dose of omega 3 fats is often associated with restricting metastatic cancer. Much research has shown that omega 3 fats help prevent cancer. In the case of breast and colon cancer, the data would suggest the opposite. Biopsies of breast tissues that showed benign growth were high in omega 3. In biopsies that were cancerous, omega 3 levels were low.

A daily dose of at least 4 grams of high quality omega-3 oil should be taken to decrease the effects of chronic inflammation. Chronic inflammation and insulin sensitivity are the driving factors to many health implications; cardiovascular disease, diabetes, arthritis, autoimmune disease, and cancer. A healthy goal should be to contain a high level of omega 3 concentration in the blood which will help the body ward off the toxic effects of oxidative stress. Along with a high dose omega 3 supplements, foods that are high in omega 6 should be avoided.
Individuals should increase the intake of high quality fats, low in mercury and toxins in their daily nutrient repertoire. In terms of diet and omega-3 supplementation, quality plays an important role in achieving maximal health benefits. The body will not absorb nutrients properly when it is exposed to harmful agents, all stemming from inflammation.
As indicated in the article, “Experts do not agree.” Scandinavians and Japanese who eat huge amounts of fish do not have above average rates of prostate cancer!

  1. Taylor Nichols :

    Thanks for posting this! Always looking for good articles associated to inflammation. Thanks for the recourses!

  2. Rachel Parker :

    Any recommendations on fish oil/Omega 3 supplements? My Nature Made 350mg of omega 3/pill seems a bit weak sauce if I should be at 4 grams a day.

    • Joylyn :

      Rachel,
      Many different brands have “high dose” or “high concentration” Omega 3 lines, so it just depends on your preference regarding taste, pills vs. liquid, etc. Often times, liquid form will have a higher concentration than the pills. Also, pay attention to the EPA/DHA concentration, because that is the beneficial Omega 3’s for your body and really the only Omega 3’s you should be counting toward your daily total. We carry the SFH Fish Oil because it’s a liquid, high dose, quality form, but for athletes that don’t care for the liquid form, the PurePharma pills are another good alternative to try.
      Let us know what you think! We love to hear feedback either way.

  3. Nikki :

    Where did the 4g/day recommendation come from?

    • Joylyn :

      Nikki,
      The 4G/day recommendation is included in this article from the author. In our Nutrition workshops, we have always discussed 3G/day of DHA/EPA total for our athletes to benefit the most from decreasing chronic inflammation, improving recovery, etc. Many athletes may adjust that relative to their own training load, lifestyle factors, diet, etc. Our 3G/day discussion is based off of Dr. Sear’s recommendations.
