I have recently bought a book called ‘The Savvy Shopper’ by Rose Prince. This is not a nutrition book per se, but contains a directory of foods and gives details about their manufacture. It is intended to be used as a guide to purchasing ethically responsible food, and also those which have the safest processing methods. For example, we have all heard stories about apples being kept in cold storage for up to a year before reaching our supermarket shelves, well this book will tell you exactly how apples are harvested and where they come from. And it covers a whole range of foods and drinks.
An extremely useful book!
