Lactose intolerance is the inability some people have to digest lactose, the sugar found in milk. It is caused by the absence or a low level of lactase in the small intestine of many people around the world. Typical symptoms of lactose intolerance are, among others, nausea, gas, diarrhea or belly pain, always depending on the amount of lactose the person can tolerate. This books invites you to travel to the universe of someone who is intolerant to lactose. Going through the life of Oriol Sans, president and founder of ADILAC —the Association of lactose intolerant people in Spain—, you will learn about all available information and progress made concerning this food intolerance. Oriol's account of his own experience, as well as his very empathetic attitude will help you to easily understand lactose intolerance from a medical, dietetic and mostly personal point of view. This book includes a questionnaire with 100 questions and answers about lactose intolerance collected by Oriol Sans throughout the years he has devoted to find out different aspects about this intolerance, including product recommendations, diagnosis methods, what to do in a restaurant and so on.
