I bought this book 3 years ago and am still referencing it now. It has totally changed my outlook on food and what I am eating.
If you are just interested in nutrition as a whole, i would highly recomend this book as it sets out the fundamentals in an effective and understandable way. The incidence of cancer and how food can help or hinder is not the overriding theme in this book but is discussed along the way with reference to diet.
Lots of helpful recipes and anecdotes along the way. I actually enjoyed reading this!
