Hm, I suppose I didn’t keep detailed enough notes on what I did – or perhaps it was an uneventful day. So, I suppose I will have to just write about something random that does not relate to my day. So, today’s question is: why does asparagus make your pee smell?
A:
Asparagus contains a sulphur compound called mercaptan. It is also found in onions, garlic, rotten eggs, and in the secretions of skunks. The signature smell occurs when this substance is broken down in the digestive system. It is still disputed that not all people have the gene for the enzyme that breaks down mercaptan, so some can eat asparagus without stinking up the place. One study published in the British Journal of Clinical Pharmacology found that only 46 percent of British people tested produced the odour while 100 percent of French people tested did. Insert your favourite French joke here: _______________. However, in the 1980s three separate studies concluded that most people do produce the odorous compounds after eating asparagus, but only 22% of the population has the autosomal genes required to smell them.
