alt Hacker NewsIt's really unclear unfortunately.
The correlative effect is quite clear, i.e people who have high omega 3 levels (eat a lot of fish) have health benefits.
But in random controlled trials Omega 3 supplements have not had convincing effects.
It might be because the supplements aren't very good, or because there's actually something completely different going on, like fish displaces less healthy foods from the diet.

what is "a lot of fish" in this context? Sushi for lunch every day? Thanks for engaging with this in a helpful way.

I wonder about cultural and ethnic confounding factors
'the supplements aren't very good' would be believable - a quick glance at the market shows a whole lot of fish oil supplements that provide low amounts of Omega 3s in large amounts of fish oil. Look closer, and you realize a bunch of them are rancid too.
