I've read most of the books written by Michael Pollan and his ilk. I support beyond organic and try to avoid packaged foods.
Having said all that, I was quite taken aback by some of the things you learn in this book.
For instance the sections on the growth of industrial agriculture in 19th century America is fascinating.
What is less interesting is the author's blow by blow account of the consolidation of the meat processing industry. She cites each and every person and in mind numbing detail.
In sum, this book is a very methodical summary of the history of the meat processing industry in the USA. There's almost no analysis or criticism.
She does criticise Michael Pollan and his type once in the book, but never answers or provides a solution to the critical problems of waste management, disease, monoculture etc.
