But I have learn how to read the labels and has some pretty low carb bread that don't take up your whole mean alotment.
That's fine, but grains, whole or otherwise, contain starches and sugars.
Example
Total carbs 17g minus fiber 5g so it is only 12g. which for 2 slices makes it 24g. (it might be only 12g(??)since serving size listed is two slices.
Some packages are 1 servings.
There are some lower or higher in grams
That turns more of the starch into sugar so the yeast can eat it and produce gas to make the multi-grain bread rise.
Not sure this is good for you.
Cooking/baking doesn't destroy all that alpha amylase in the white kidney bean extract, so you get that added to your complement of things turning starch into sugar in your body and it's gotta' have a major effect on your blood sugar level.
So, yeah, low carb bread can turn into high carb bread when you eat it!
It's a trick.
