Surprising findings on omega-3s, trans fats, and prostate cancer risk don’t warrant a change in diet

I’m not sure I buy this study at all either. After increasing my Salmon intake my PSA levels didn’t increase, to the contrary, it dropped. I also added more fiber to my diet, Oatmeal and Bran.

What this study shows to me is that men who develop aggressive prostate cancer tend to modify their diets to increase Omega 3 and reduce transfats, thereby giving the appearance, after developing the disease, that less O3 & more transfats in blood is found in those who do not have aggressive prostate cancer, and conversely, more O3 and less transfat in blood is found in those who do. This is a good example of how a study can be interpreted incorrectly.

When you ask your doctor or any doctor(specialist)about prostate cancer, cholesterol, cardio-vascular related problems, blood pressure, diabets1,2 the answer will be, you have to avoid saturated fats, trans fats, etc. and gives you advise to chenge your diet(eat vegetables fruits Omega3 rich foods), do excercise, approach to proper weight,etc. it seems that all these illeness have a common trigger, then what is taht common trigger? i think this need deeper researchs on the matter.

I too would be interested in knowing the incidence of prostate cancer in Japan and surrounding areas that consume large amounts of Omega 3.

I am a nutritionist and have learned that men that consume large amounts of omega 6 increase their risk of prostate cancer?

My husband has had prostitis for 6+ months. He has been on antibiotics for all this time and still has symptoms. We have taken him off omega 3 for now. What is causing this inflammation and why can no one treat it. My Osteopath suggested he could release some of the scar tissue from all the inflammation, any thoughts or recommendations would be greatly appreciated!!!

So… no Omega 3 supplements?

Once again the epidemiologists have stirred up some cloudy soup! The contrairian results of this study are so outstanding that they have to be approached with great caution. The statistical analyses shows confidence limits around the mean values big enoug to drive a truck through.

So before anyone dumps the accepted wisdom regarding omega 3’s and their ilk, let’s see if anyone replicates the results. Keep the grill hot and the fresh fish broiling!

I second the request for absolute numbers.

It would be interesting to know if countries with really high fish consumption, like Japan and Iceland, have high prostate cancer rates.

just basing research on diet and food without looking at pesticide residues in fat and lipid production and the resulting endocrine disruption and neurotoxicity is falling short.Prostrate cancer may be caused by stress? There is no greater cause of oxidative stress in my view than the continued use of excess pesticides with associated penetrants or surfucants designed to permeate the plant waxes possibly causing chaos in the human fat and lipid chain.

I wish the absolute risk increase had been given. This report doesn’t give sufficient information to make an informed judgment. What is the value that is increased by a factor of 2.5? If it is very low then it’s not a big deal. If it is not so low then there is reason for concern.

What would be a moderate amount of salmon? I consume about a pound of wild salmon a week.

Are there still any cultures still known for a high salmon or other high omega 3 fish diet…say in the Pacific coast areas from British Columbia to Alaska? If so, it would be interesting to know of the prostate cancer incidence rate in those populations.

The nutritionists I’ve spoken with recommend eating 4 to 6 ounces of fish three for four times a week.
