Janet: I've been a diabetic for about 17 years and on insulin for most
of that period. I watch my carbs pretty carefully and try to eat
healthy. We eat multi-grain bread, whole wheat pasta, brown rice, etc.
and I seem to do better on it. The advantages of whole grains, in
addition to all the minerals and vitamins that refining takes out of
grain, is that it has a little more fiber and, more importantly in my
case, it takes longer to digest. Thus slowing the immediate impact of
eating the carbs. If I eat white rice, my blood glucose levels go
straight up almost immediately, brown rice the BG levels rise slowly and
my insulin can take care of it.

This is only my experience and I can't speak for others.
