So, how much tuna can you actually eat without turning into a science experiment? The short, boring answer is: it depends on your body weight and the type of tuna. But let’s cut through the jargon and talk like normal humans.
The main villain here is mercury, which is like that one friend who overstays their welcome at a party. It builds up in your system, and it’s especially unkind to pregnant women and young kids. For the rest of us, it’s about moderation—not panic.
Think of your body like a bucket. Mercury drips in slowly from tuna, but your body also leaks it out over time. The trick is to fill the bucket slower than it leaks. Eat too much tuna every week, and you’re basically using a firehose.
Breaking Down the Numbers (Without the Math Headache)
Here’s the cheat sheet that won’t require a calculator. For chunk light tuna—the cheap, reliable stuff you mix with mayo—you can go for two to three servings per week if you’re an average adult. A serving is about the size of a deck of cards, or roughly one small can.

But if you’re a fancy pants who loves albacore or white tuna, slow your roll. That stuff has three times more mercury than light tuna. It’s like comparing a glass of wine to a pint of whiskey—both are booze, but one hits harder.
For albacore, the advice is usually one serving per week for adults. Pregnant or nursing? Drop that to a single serving every other week. I know, it’s a bummer, but that’s what the experts at the FDA say.
