Omega 3 supplement prostate / heart health

Answered on August 19, 2014

My dad just sent me an interesting article that mentions "Omega-3 Supplements Linked To Prostate Cancer".

http://www.nbcnews.com/health/fish-oils-may-raise-prostate-cancer-risks-study-confirms-6C10597283

The article goes on to say:

It might be a sign that popping a pill is not only possibly a waste of money ??? it might be downright dangerous. And eating fish too often might be, also.

Men with the highest levels of one omega-3 fatty acid called docosahexaenoic acid, DHA for short, had double the risk of high-grade prostate cancer. Other studies have had similar findings.

A 70 percent increased risk in high-grade prostate cancer, given it???s the No. 1 cancer in men and fish is a commonly consumed thing and is thought to be a healthy food, I think it???d be a concern for people

The researchers point out that recent studies have shown taking extra omega-3 has little effect on heart disease ??? including a study published in the New England Journal of Medicine in May.

I've been taking a teaspoon of Nutrasea TG-form oil (800mg DHA / 300mg EPA) on days that I don't eat seafood, occasionally switched out with a FCLO+butter oil capsule. Should I quit doing this?

My diet is 100% Paleo -- exclusively vegetables, meats, and fruits, at around 40/30/30 with lots of starches. I'm an Apoe E3/E4 genotype.

Thoughts? (Just last week I was explaining to him how Omega-3's are one of the healthiest things you can eat and that my supplements were of a high quality.)

Edit: From reading this article, it seems the whole diet and total omega-6 in context matters:

Nevertheless, molecular mechanisms of omega-3 PUFA effects on prostate cancer remain elusive. Our data show that the high???omega-3 diet, with an omega-6/omega-3 ratio recommended by nutritionists, could effectively deliver omega-3 PUFA to the prostate (Supplemental Figure 2), delay tumor formation and progression, and prolong survival as compared with the high???omega-6 diet.

Still, I'm curious about the extra supplemental DHA/EPA on a lean Paleo diet.

That sounds quite reasonable. Prostate issues are inflammatory. The idea that fish gives you cancer has to be one of the weirdest things I have heard!

Maybe it's the pcbs in fish.

the article here on prostate health http://www.pumpkinseed.net.au/articlepages/pumpkinseedoilprostate references a 'correct ratio' of Omega 6:Omega 3 of between 2:1 to 1:1 (disclosure, note the site does produce & sell pumpkin seed oil)

This may be a stupid answer,,, but "The group included in the this analysis consisted of 834 men who had been diagnosed with incident, primary prostate cancers (156 were high-grade cancer) along with a comparison group of 1,393 men selected randomly from the 35,500 participants in SELECT. " is it possible that the men with a worse prognosis were also more likely to desperately be reaching for straws (taking fish oil supplements)?? This wasn't a randomized follow up of people over years. They compared people with prostate cancer to those without. Seems like a lot of those guys might be taking fish oil supplements just to cover their bases. I mean, otherwise it's hard to make sense of this study... I mean, fish doubles cancer rates of the prostate but cuts digestive cancer risks across the board?

Big pharma scaring the little guy away from fish if you ask me...

This is very helpful indeed! thanks @BGottfried! As for me, everything should be in moderation. I don't want to stop taking fish oil but have to use it moderately.
