True this book has some very basic agricultural knowledge, including chapters on things like eggs, wool, beef, poultry etc - but there are lines in the book that literally churned my stomach. The beef and poultry industries may as well have written this book themselves. My favorite that I came across so far was in the Dairy chapter where it informs you that lactose intolerance can be overcome by consuming more dairy. I'm sorry - but I continued to consume dairy for over 10 years while they tried to figure out what my "mystery illness" was and it ended up being a food allergy to dairy. Being a biology major I love how so much of what is said in this book as random comments seems to NOT be based in scientific fact. I mean sure the diagram of the egg is great, but when there are comments about people overblowing health issues of these foods it leaves me questioning the validity of the rest of the book. If you're already drinking the kool-aid of the various industries then you will be fine with this book - but if you have taken classes like Microbiology or Immunology then you'll be left scratching your head as you try to reconcile the information contained within.
