Beans and blood sugars

Someone sent me an emai saying that beans were good in stabilizing blood
sugar in diabetics.  At first I ranted and raged that this was not true.
I decided to check it out and went to google where several articles are
saying that.  I know there is a lot of fiber, but the heans I think of
have lots of carbs.  they didnt mentioned any beans except green beans
which I put in a vegetable category.  I think of baked beans, refried
beans garbanzo beans.

My question is what do you know about this and what has been your
experience.  In my own person case I ****tion control baked beans to two
ounces so the effect is minimal
