Kris, Dave and the Lumps: BRAT diet... what is that?

Ok, got a couple of questions on the BRAT diet and reviewed my notes... as
an example of missing details, I thought I'd given the definition on the
June 4th update but did not. Michelle had prescribed a BRAT diet to help
Kris get regular and here is what it is:

BRAT = Bananas, Rice, Applesauce and Toast

Makes for a boring, bland diet. The foods are considered constipatory or
anti-diarrheal. Since they are simple foods, they tend to also reduce
nausea affects. This is a diet that you usually see prescribed for
children but, works fine for adults too... so, many of you probably already
know this diet if you have kids, just not necessarily by the name 'BRAT'...
and now you know why Kris is desperate for something more substantial to
eat.

This should answer the question "is this some sort of Chicago diet
consisting of Brats and Beer?" :)
