This is an excellent book to improve your wellbeing, mood and motivation. Written in simple language for the layman Patrick Holford addresses issues with explanations and tells you how by changing your diet and lifestyle you can feel good with energy all day long. A must read for everyone, whether or not you feel you need this book. Young people may feel fine now, even with a lousy diet, but Patrick shows that this will not last and that disease begins with poor diet then escalates to worse issues like diabetes, heart disease and cancer as other body systems become affected.
