Examination of Dietary Patterns and FODMAPs Intake in Patients with Irritable Bowel Syndrome


Innovations in Healthcare (The Ohio State University Denman Undergraduate Research Forum)Background: Utilizing a food frequency questionnaire (FFQs) to determine current dietary practices of those with and without IBS allows the Registered Dietitian Nutritionist (RDN) to understand usual dietary intake as it related to FODMAP ingestion. Objective: To identify the average lactose, fructose, and polyol intake in people with and without IBS to gauge if there are differences in usual dietary intake. Methods: VioScreen™, a web-based FFQ, was offered to all patients attend a gastrointestinal outpatient clinic at the Ohio State University Wexner Medical Center to assess dietary patterns and lactose, fructose, and polyols intake. Those that completed the FFQ were stratified into those with and without IBS. Results: Participants (N=140) were included in this study. Mean age was 43.0 ± 15.5 years with an average BMI of 28.2 ± 7.4 kg/m2. No difference in the average fructose (36 g ± 38 vs 25 g ± 34; P = 0.156), lactose (14 g ± 10 vs 12 g ± 14; P = 0.655) and polyols (1 g ± 0.5 vs 1 g ± 0.6; P = 0.260) was detected between those with and without IBS. Conclusion: Patients with IBS do not consume significantly less fructose, lactose, and polyols compared to patients without IBS. Data suggests high-FODMAPs foods can trigger IBS symptoms. RDNs should evaluate the dietary patterns before the education of low-FODMAPs to ensure the education is targeting patient-specific high FODMAPs foods.Funding for this project supported by CTSA grant number (UL1TR002733)No embargoAcademic Major: Medical Dietetic
