As practitioners, Prof Phelps and Dr Lee know the problems caused by poor gut health and how an uneasy gut can make life miserable. Symptoms such as weight gain, diarrhoea and cramping are common, but few people receive a definitive disease label. Most of us are entirely unaware that by taking care of our gut we can improve our overall health. In this meticulously researched and highly practical book, the doctors explain how we are on the threshold of a major revolution in the way we think about the gut and its relevance to our health. They explain common medical problems - from IBS to various food intolerances - and show you what's going on and what to do about it. Featuring a comprehensive guide on the mysteries of microbiota, a plethora practices and treatments to restore your energy, and 30 recipes to revitalise and heal your gut - produced with nutritionist and clinical dietitian Jaime Chambers - this is an essential guide to fixing your gut and improving your wellbeing.
