Why work with a gut-specialist dietitian?

9 in 10 Gastroenterologists agree on this...

Access to GI-specialist dietitians dramatically improves IBS patient care, without requiring extra time from the doctor (Scarlata K, et al. Am J Gastroenterol. 2022).

Doctors are a trusted source, however...

Patients view generic diet handouts as simplistic, non-personalized and difficult to implement (Trott N, et al. Nutrients. 2019).

The benefits of a low FODMAP diet are...

Based on the collective research of interventions led by a dietitian, not from patients navigating it on their own (O’Keeffe M, Lomer M. J Gastroenterol. Hepatol. 2017).
