6. The fish odor syndrome
The next body odor on our list is fish odor syndrome, which is actually the popular name for a health condition called trimethylaminuria. This is a very unique genetic disorder, in which the enzyme FMO3 in the body fails to do its job the way it should and no longer breaks down trimethylamine.
In conformity with the National Institutes of Health, this substance is a chemical that can be found in foods like beans, organ meats, eggs, and milk.
This chemical compound contains an acid, sulfurous odor that smells like rotten eggs or fish. Studies believe that there is no magic cure to get rid of this annoying affection, but there is actually a thing that you can do to minimize the effects, which is avoiding foods that contain triethylamine.
