Why Asparagus Makes Your Urine Smell Odd

In their latest video, BytesizeScience explains how eating asparagus can lead to odd-smelling urine. Interestingly, not everyone can detect the odor and not everyone generates it when they eat asparagus. And as Wikipedia points out, the phenomenon has been observed for centuries:

“A few Stems of Asparagus eaten, shall give our Urine a disagreable Odour…” (“Letter to the Royal Academy of Brussels,” Benjamin Franklin, c. 1781)
