Funny you should ask that.  I considered this very same question a long time 
ago.
I found nothing regarding this in all my searches, although a lot of researched 
stuff which may, repeat, *may* have shed some light on the subject one needed 
to pay for the privilege of reading, and I'm not into subscribing to anything 
of uncertainty.
Due to the makeup of EIS/CS I have a mind to think it may do something, and 
possibly over very long term of continued consumption, but I'd reckon without 
some firm evidence I would be the only one who thinks that.
