I heard Mr Pollan on Radio 4, and was impressed. The book is well worth persevering with, it is crammed with well researched information.
This is not a diet book, it is an anti-diet book. It arms you with all the tools you need to make up your own mind about food.
It is easy to become almost evangelical about this book, but it is a really important piece of work. Nutritionalists should not worry, the world still needs you, but this book makes you wonder about the way that major corporations use this information to boost profits.
