As the name suggest, this book may be regarded as the sequel to What Should I Eat? Book 1, which focuses on healthy eating in general. In contrast, What should I Eat? Book 2 shows how food and diets can cause, prevent or reverse specific illnesses. As with book 1, this book is not preachy or one sided. It takes a balanced approach to food and health and avoid the pitfalls of one-size-fits-all thinking regarding food and diets.
