Welcome to the forum.
I see what you are saying but since the dry Aunt Patty's stuff in itself includes some complex carbohydrates, it may be those carbohydrates that are easily digested. Also, if the Aunt Patty's product contains diastatic malt, then I would think that the information would be on the package also, or at least reference to the effects of the malt. Everything on the package pertaining to the product's benefits (color, flavor, etc.) suggests the non-diastatic form of malt. When I went to the Aunt Patty's website, I saw nothing there on diastatic malt, only discussions of sweeteners, both dry and wet.
