Query: Worst Written Book on Digestion Ever

It's hard to even get to the content of this book because it is written so poorly. There is no index and no rhyme or reason to the order of the book. The ghost writer has advanced degrees from Stanford (or somesuch) and apparently has never written a book before this vanity effort.The content is so so at best. The author has no formal education in biology or medicine and wants everyone to eat raw, rotten cabbage. Beyond that, she seems to buy into the blood type diet just to have a hook into modern bad science.All in all, save your money and get a good nutrition book from the library.
