You can't eat too much fish, right?

I mean there have been cultures living by the sea or lakes whose diet was principally fish. Comments please.

In context, a ton of fish may not be harmful to ingest. However given arguments that are out there about ocean toxins etc, it is arguably prudent not risk a long term buildup.

@thhq theory and practice relate. Particularly in the contemporary industrial world it is reasonable to say eating a ton of fish has drawbacks given what we know in theory. Yeah I agree levels of toxins are very variable etc and is difficult to know in practice, as it is for many things. Hence why not eating a huge amount of things where there are known (theoretical) drawbacks is prudent.

Sorry vb, downvoted because of articles similar to the ck one above I've read that show selenium protects against the mercury in many fish (especially smaller ones). Ever wonder why whales and dolphins don't get mercury poisoning? I know I have, they're mammals too. All the epidemiological studies show more fish higher brain function which flies in the face of mercury toxicity from fish and the brain.

Especially if you ate the same fish very often, like canned tuna for instance, you will build up toxicity from the pollution. Best to vary the source and skip days. Unless you have a source of wild freshwater fish from water bodies that have no tributaries that pass through agricultural nor industrial property.

There's a good section on Omega-3 in PHD. Here's a quick summary that may be helpful:

Eating a ton of cold water fish is probably unhealthy, due to it's high omega-3 load. But if your omega-6 intake is high, then increasing omega-3 might have benefits, as it can partially remedy o6 toxicity. The best case is to lower your PUFA intake overall and have them at a ratio more like (3:1 o3/o6).

Omega-3 toxicity can include liver damage (especially when eaten with alcohol or fructose) increased risk of stroke, and accelerated aging.

Lipid peroxidation of o3 is even higher than o6, which makes it very volatile.

The Japanese consumption of o3 is equivalent to just a pound of salmon a week. Clear evidence of o3 toxicity begins at 2 lbs/week.

Sounds like you should eat fish like the Japanese and keep your daily portions quite modest.

I do adore Eel, Chilean Sea Bass, and Yellowtail but try not to eat them that often... Although sometimes Eel because slightly regular part of my diet... WHOOPS! LOL!

Mercury poisoning and other toxins. Plus most fish is farmed these days. And the ones that are not farmed are from some infected waters. Yes, you can!

Unless you live on a remote island far away from all pollution sources and catch this fish every single day. But then you would not have access to the Internet and Paleohacks.

So here you go.
