Hey Don, do you like asparagus? Yep, I love it Yael, can't get enough. But don't you notice there's a certain problem after you've eaten it? Problem? Yeah, everybody knows that eating asparagus can cause a rather unpleasant smell in your urine. I didn't know that. Oh, that's right. Not everybody is an excretor of the odoriferous compound. And not everybody can perceive the odor, either. Both those traits are genetic¹. But what causes it? well, that's a good question. No one’s really sure. We do know that the pungent² chemical is some kind of sulfur³ based compound. But scientists have been trying to find the exact identity of it since the 1890s.More recently, researchers found out that the smell is actually caused by a malodorous cocktail⁴ of six sulfur containing compounds.
