The link between fish consumption and neurobehavioral abnormalities in adults is likely related to mercury toxicity.
Fish Fog
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 subclinical 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 how fast you can tap your fingers.
