There are several contradictions in the book, on the question and answer forum about B's eating wheat flour, but not wheat bread, he answered to something totally irrelevant, and would not deal with it. I wanted to ask a similar question, if I can have all dairy why not ice cream. He does't answer mail anymore. I wonder why? you can forward this to him if you can find him. I was going to recommend this book, however I will not now.
