The foods that make you smell more attractive
Meat and fish
Meat and fish can also produce a distinct body odour as animal proteins are broken down by the body into amino acids and fats, which are then excreted through sweat – where they interact with skin bacteria.
Fish and beans, for instance, can cause body odour because they're filled with trimethylamine, a very strong-smelling compound. There's even a health condition, called trimethylaminuria – also known as "fish odour syndrome" – which arises when the body can't turn trimethylamine into a non-smelly compound, says Beeson. "This can lead to a strong body odour," she says, but this condition is quite rare. For instance, a 2025 case report recounts a 10-month-old boy who developed trimethylaminuria and began smelling like rotting fish after eating fish including swordfish. The condition was transient, and through careful management he was eventually able to eat fish without the symptoms reoccurring.
