I'm glad to see somebody else doesn't cook ingredients. I think there is fine line between trying to prevent symptoms and then being held hostage. To me, cooking oats, bread, and broth (and fruit juice) is absurd. Nobody should be required to do that, if you can't eat store made bread, I don't see what hope you have.
Moreover, come on, I hardly see how making bread and oats v store bought makes a difference between feeling good and bad. To me, that seems well above and beyond reason. Very few people make oats, bread, and juice, they buy because we have lives and cannot live in a bubble.
