Taking omega-3 fish oil supplements may increase the risk of aggressive prostate cancer by 70%

Any comments?  Any truth in this or is this just big Pharma attempting to scare people away from supplements?
If there is any truth, would it be the same for Krill oil and fish peptides etc?

These types of studies are junk science plain and simple.

The same irresponsible team that sought out to demonize vitamin E, which was an absurdly poor study design.
The wrong type of vitamin E, a single fraction, etc...

Meta analyses are just as bad as questionnaire data, perhaps worse.

However, having said that....high dose omega 3 as with other things that can blunt DHT (an anti-carcinogenic hormone metabolite) will create a similar result.

Testing vitamins or other substances in isolation yields poor results.

I agree that fish oil may not protect against heart disease or stroke....however, it does do something else.
Something else more valuable. For one thing, when you combine fish oil or other Omega-3 with a plant based
antioxidant, you'll receive a better benefit. The primary benefit with some form of Omega-3 is activation of enzymes that slow the telomere aging clock...and it also reduces PGD2.

Prostate cancer itself is largely preventable by first ensuring that there is no varicocele present..which is an enlargement of the veins in the scrotum. This leads to a back up in unbound testosterone from ever reaching general circulation, then causing a rapid proliferation of prostate cancer cells in that area. Otherwise, prostate cancer cells generally just remain dormant and are slow growing. There is a heat shock protein that is correlated with the deadly type...if there's a negative for it...then having the prostate cancer doesn't matter, it won't kill you unless you have a positive for the HSP marker.

In other words, conditions that cause a decline of testosterone is where to look. Adequate levels of vitamin K2, will help keep prostate cancer in check. How? It strengthens the vascular system and boost testosterone levels. It also keeps calcium in check.

Selenium and iodine is an important combo...Of course researchers typically test one or the other, rarely in combination...Just like vitamin D and vitamin A, they need to be used together, not apart.  Otherwise messing with nature will cause bad results.

Consider that the average person is deficient in Omega 3s, while DHA especially comprises 40% of brain PUFAs and 60% of retina PUFAs. DHA also comprises 50% of neural membranes. So if you value your brain, eyes and general functionality, throw this myopic junk science in the proper bin.

What I do recommend for fish oil supplements is finding the right source to avoid oxidation and rancidity, also refrigeration is important. If you have enough money to spare, krill oil is a good solution as the phospholipid content greatly increases absorption and the astaxanthin content ameliorates any chance for oxidation.

I personally take Swanson's  Super DHA 500 sourced from Calamari along with some lecithin and astaxanthin daily.
