Fatal Flaws in New Review of Omega-3 / Cancer Prevention Link

Print

The Journal of the American Medical Association (JAMA) recently released a "meta-analysis" of several dozen studies on omega-3 fatty acid intake. The authors came to the conclusion that dietary omega-3 fatty acids are unlikely to prevent cancer. 

However, many experts on the subject of omega-3's and cancer, including Dr. William Lands and Dr. W. Elaine Hardman, agreed that the data from the studies was inadequate and unsuitable for the kind of analysis it was subjected to.

These problems, they argue, make it impossible to come to any meaningful conclusions from the data.

Problems in the studies included:

  • They failed to determine or consider two key factors: omega-6 intake and overall dietary patterns over time

  • They did not distinguish between intake of plant omega-3s versus marine omega-3s, or between lean and fatty fish, whose omega-3 content can vary by factors of 10 to 20.

  • Participants' diets were relatively low in fish (e.g., one-half serving per week), and therefore also low in marine omega-3s, in many of the studies that showed no cancer-preventive benefit

  • Cancers take years or decades to develop, but most of the population studies took only brief snapshots of participants' dietary habits

 

Dr. Mercola's Comments:

Don't you just hate it when the media gives you mixed messages? One day fish is healthy the next day it isn't. Who are you going to believe?

Well that is one of the primary purposes of this newsletter, to give you my additional insights on breaking health news to help you sort through all the material. This way you can make an intelligent decision about what is true for you.

This JAMA report on omega-3 fats could have dire health consequences for you if you decide to follow its conclusions.

Unfortunately, due to the sensationalist nature of these "findings," it has picked up some steam in the mass media and is being presented there as truth when in fact it is anything but the truth.

Extensive and strong evidence has shown that omega-3 fats from fish can indeed help prevent cancer. Furthermore, other studies have demonstrated these fats can be very highly effective at helping to:

In my two-decades-plus of clinical experience as a physician, I have witnessed this same strong correlation between fish oil and improved health. Regularly consuming fish oil and clean, healthy fish is one of the strongest recommendations I can advise, as most reading this newsletter are dangerously deficient in omega-3s from marine life.

However, be warned that fish would be one of the planet's healthiest foods except for one very dangerous and sad issue -- nearly ALL fish from ALL sources (ocean, lakes, rivers, & farm-raised) is now highly contaminated by mercury and other toxins.

I strongly urge you NOT to eat any fish unless you are absolutely certain it has been proven free of dangerous levels of mercury, PCBs, etc.

One fish I DO highly and confidently recommend (the ONLY one I personally trust and consume) is the Vital Choice line of fresh and canned wild red salmon. Their salmon comes from pristine Alaskan waters, tastes delicious, and I have personally had their salmon laboratory-tested.

I encourage you to check out and try the Vital Choice line of wild red salmon now, including the filets, smoked salmon, kosher lox and more!

For most people, though, fish oil supplementation is a far more cost-effective solution.

When using fish oil it is important to obtain a high-quality reputable brand. In my research -- and in my clinical experience with my patients -- I have found that:

  1. The liquid form is superior to capsules
  2. Certain brands definitely seem inferior to others
  3. The Carlson's brand of fish oil/cod liver oil is of an exceptional quality and purity

It is likely not the only brand in the world of such high quality, but up to this point it is the only one of such quality that I can recommend, so I now offer the Carlson's fish oil and cod liver oil on Mercola.com; you can also check your local health food store to see if they carry it.
