Abstract BACKGROUND: Diets rich in fermentable residues increase intestinal gas production. Our aim was to demonstrate the potential effects of diet on gas-related symptoms. METHODS: The effect of a low-flatulogenic test diet (restricted to foodstuffs low in fermentable residues; n = 15) was compared to that of a balanced control diet (Mediterranean type; n = 15) in 30 patients complaining of flatulence and other abdominal symptoms using a randomized parallel design. The following outcomes were measured daily: number of anal gas evacuations by an event marker, severity of gas-related symptoms by 0-10 scales, and sensation of digestive comfort by a -5 (unpleasant) to +5 (pleasant) scale. Measurements were taken pretreatment for 3 days on their habitual diet and for 7 days during the treatment phase. KEY RESULTS: No pretreatment differences were detected between patients allocated to the control or test diets. The test diet significantly reduced the number of gas evacuations (by 54 ± 10\%; p = 0.002 vs basal diet) whereas the control diet had a lesser effect (reduction by 28 ± 9\%; p = 0.059 vs basal diet; p = 0.089 vs test diet). Compared to the control diet, the test diet significantly reduced flatulence (by 48 ± 7\% vs 27 ± 8\%, respectively; p = 0.018), abdominal distension (by 48 ± 4\% vs 22 ± 12\%, respectively; p = 0.038), and enhanced digestive well-being (by 149 ± 18\% vs 58 ± 22\%, respectively; p = 0.006). CONCLUSIONS & INFERENCES: In patients with gas-related symptoms, a low-flatulogenic diet produces immediate beneficial effects with digestive, cognitive, and emotive dimensions. The number of gas evacuations is an objective biological marker of response to dietary treatment. © 2014 John Wiley & Sons Ltd.
