Alex Mercer has lived with IBS since childhood and isn't a nutritionist or a doctor. After years of being told he was anxious or would grow out of it, he spent more than 12 years reading the research properly, and now shares what he has learned with the family, friends and support-group members who come to him with the same questions. He translates peer-reviewed research into practical, honest advice, and is always upfront about what the evidence does and does not show.
