Asparagus
The unfortunate results of eating asparagus don’t appear through lousy breath. They show up MUCH later, if you get what we mean. They produce very persistent acidic urine, as intense as rotten or boiled cabbage, because of its natural decomposition.
In a 2011 study, researchers proved that people have odors and perceive them due to their genetic variations. This healthy side dish makes the urine of some unlucky people smell terrible, an odor often compared to rotten cabbage.
Surprisingly, these studies also observed that not everyone could smell the foul odor. Even those who produce it sometimes can’t smell it, so you could have a terrible case of BO and not even realize it.
The culprit behind the bad smell is mercaptan, a sulfur compound metabolized and filtered out of the body through the kidneys. But there’s good news! There are no health repercussions associated with asparagus urine.
Still, there is also no way to prevent it, so avoid asparagus in a restaurant or a public outing if you’re worried about the bad smell.
