I am wondering about one thing. I have read different accounts of this (prior to reading it on Wikipedia), so I am wondering.
Here are the two versions I have read:
- asparagus leads in a certain percentage of people to a smell that has to do with a reaction of asparagusic acid. That is: not every human body creates the reactions leading to the "smelly" thiol (sulphuric) compounds.
- asparagus leads to the processes of the aforementioned asparagusic acid in everybody but only a part of the population is able to smell those compounds.
Which one is true? Or is perhaps some other version I haven't heard about.
btw: The Wikipedia article on asparagus references both versions, too. So I am hoping for a definite answer with references to the respective scientific papers/studies.
