Maltodextrin and starch are absorbed as glucose, and just as
fast. The reason is that it is the glucose absorption that is the
rate-limiting process, not the enzymatic
breakdown of the polysaccharide at the brush border
of your villi, which happens BEFORE you absorb the glucose
which is the result of the breakdown.  In other words, it does
no good for you to eat maltodextrin or starch, because they
are digested to glucose in your gut faster than you can
absorb glucose. You might as well eat glucose.  So far
as your body is concerned, that's what you ARE doing.
