I’m not going to sugarcoat it: eating fish can make you smell a little… well, oceanic. But before you throw out your flaky white cod, hear me out—it’s not what you think.
The culprit is a compound called trimethylamine (TMA). When you eat fish, your gut breaks down a compound called TMAO (trimethylamine oxide), which fish naturally use to survive in cold water.
Here’s the kicker: your body converts TMAO into TMA, and that’s the stinky gas that escapes through your pores and breath. It’s like your body is saying, “Thanks for the omega-3s, but whoof, now you smell like a fishing boat.”
Does Everyone Get the Stink?
Not everyone! It depends on your genetics. Some people have a superpower called “efficient TMA processing,” meaning their liver neutralizes the smell before it hits the air. Others? Well, let’s just say their liver is on a lunch break.
If you’re one of the unlucky ones, you might notice a distinct “fishy” odor on your skin or breath about 4 to 8 hours after eating. It’s temporary, but it’s real—and your cat might start following you around.
But don’t panic! This isn’t a life sentence. It’s more like a temporary “perfume” that fades as your body digests and eliminates the compounds. Usually within a day.
