The asparagus season has come and past, with it the pungent pee that seems to appear minutes after consuming a stalk.  I had always been under the impression that only a certain population has the physiology which creates this odor, but I’ve recently found that this is not the case.

Depending on the studies that you read, 22%-50% of the population reports a fowl smelling urine after  ingesting asparagus.  What accounts for this populations production of pungent pee?

The people who have report the odor do have a special gene, but it has nothing to do with producing the odor.  The gene that this 22%-50% possesses allows them to smell the odor.  Regardless of whether or not you smell the odor, it’s there.  If you do smell the odor consider yourself  lucky…you have a special gene.
