So I told my grandson that a little part of his brain was in his tummy. He laughed and said that was silly. I told him not to tell his teachers because even though I knew it was true, his teachers wouldn't know it. He's pretty talkative and that would have come up for sure and I didn't want him getting into an argument with his teachers. So he told his mom, my daughter. My daughter told him that he must have misunderstood because the brain was only in the head.
Anyway, I loved talking to him about signals in the brain and how it works to control things.
Oh, yes, I told my daughter YES THERE IS A SEPERATE PART OF THE NERVOUS SYSTEM IN THE GUT! I had to actually look up the Scientific American article for her.
A really good friend of mine cured, yes, completely cured Type 2 diabetes by addressing her gut issues. And it had nothing to do with weight loss or limiting carbs. She followed a book called The Body Ecology diet. I had to listen to her talk about things like kefir, and stuff I never had heard of. She had had gut issues since she was a child, and when those cleared up the high blood sugars became normal.
