R&M Dietetic is a London based dietetic service consisting of a specialist gastroenterology adult dietitian (Lee Martin MSc RD)  and a clinical lead paediatric dietitian (Melanie Martin RD). Our focus is on gastrointestinal health for both adults and children. We have special expertise on the low FODMAP diet and have also written the first ever book dedicated to the reintroduction phase of the low FODMAP diet ‘Re-Challenging & Reintroducing FODMAPs‘.
