Our bodies don't actually digest most grains, something a lot of foodies forget when they say that whole grain is beneficial. ;)<quoted text>
I had my gb removed, apparently wheat is completely unnecessary to our digestive systems, grain 'healthy' bread is no better as 'we are not birds'. Check it out, it's pretty telling. I don't have a link, my sister told me, she's a Chem Major and did food studies amongst other things, I found it online but it was awhile ago. The history behind the creation of bread to fill up poor people cheaply, is interesting too.
I take your word for it as I have also discovered the same things you have on the matter, so I have no reason to doubt it. Grain is a filler, it's to make you feel more full than you are so that you don't eat too much, basically. it can also add some consistency to the bile, if your body has the proper balance of bacteria. But after major digestive surgery, I had complications so mine was just that, or even from long term use of antibiotics, your digestive system become imbalanced and it can take decades to restore that balance. But there are also other ways the body can accomplish what grains do, one is to consume starch in place of grain.
