Now, before you swear off tuna forever, let’s talk about selenium. This is tuna’s secret sidekick. Mercury is bad, but selenium binds to it like a clingy friend, making it less toxic. Tuna naturally has lots of selenium. It’s like the fish is giving you a detox discount.
But—and here’s the fun twist—if you eat too much tuna, that selenium-mercury balance can tip. Too much mercury, not enough selenium? Your body gets confused. You might feel wired but tired. Or just plain cranky.

Scientists call this the “selenium-mercury paradox.” I call it “the reason you shouldn’t eat tuna for breakfast, lunch, and dinner.”
The Olympic Tuna Diet
Picture this: a Japanese fisherman named Kenji ate tuna nearly every day for a decade. He didn’t go crazy—he just got very, very healthy. Meanwhile, a lab rat fed massive tuna doses got sick. The difference? Kenji ate small amounts. The rat ate its body weight in tuna. Moral of the story: you are not a lab rat. You’re a human with a varied diet. And that’s a good thing.
Fun detail: one study found that pregnant women who ate more than 12 ounces of tuna a week had babies with slightly lower IQ scores. That’s not funny—but it’s a great reason to not make tuna your personality.
