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

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...
