Yeah! it tastes good!
Just kidding, I wouldn't be suprised if there was some relevance to
something. Since the sinuses drain into the GI tract and the mucosal
system is common to both systems there might be a connection. However, I
doubt eating boogers alone has a strong immunological effect simply because
the amount is so small versus what drains daily down the back of the
throat. I don't think this subject has been addressed, but it does raise
an interesting point. I have often wondered why rodents and even young
dogs are corprophagic (eat their crap). Could this help keep the transiant
food antigen levels in the gut high enough to be either toleragenic or
immunogenic. Its another one of those gross questions that just begs for
an answer. I wonder if NIH will bite?
BTW, I know you asked for a e-mail return but this might make an
interesting thread, so that's why I'm posting.
