The link between fish consumption and neurobehavioral abnormalities in adults is likely related to mercury toxicity.

Mercury affects adults too. Hair loss, memory loss, slurred speech. Here’s a case report of a guy who ate tuna every day—became so crazy he was thrown in a psych ward. Couldn’t even remember his name.
It’s not always this dramatic though. Eating fish gives people sub-clinical neurobehavioral abnormalities, meaning you feel fine, you look fine, but if you’re actually put to the test, the performance of those who eat fish is significantly worse on a bunch of tests, like finger tapping speed—like how fast you can do this. But if go up against your fish eating friends and win bets seeing who can tap faster, I get a cut.
