I feel like I should be able to understand this, but I don’t. :(
I don’t much either, really! All I know is that since we started supplementing with vitamin D around here, no one seems to get sick. Including the little autoimmune things. We don’t have a big autoimmune thing here, thank G-d, but I one of us did, I’d add testing and supplementation of D.
And when you eat grains, especially glutens, they are so hard to digest and they mess up the digestion process in your gut, which takes place because of the gut bacteria, the GOOD ones. Also, when you are eating grains, big particles can get through some of the intestinal holes and these proteins get into your bloodstream and can make you sick or give you neurological problems. Avoiding grains is a very healthy thing to do. Many of the digestive disorders like celiac, IBF, and Crohn’s can be avoided by avoiding glutens or (better) all grains.
