Specific dietary interventions are effective at eliminating small intestinal bacterial overgrowth

The retrieved literature indicates that dietary interventions (such as low-FODMAP or biphasic diets) are commonly discussed and used in clinical practice or integrative management for SIBO (supporting papers 7 and 9). However, other papers point out that evidence-based nutritional guidelines are lacking and that dietary approaches often focus on symptom control or adjunct therapy rather than proven, standalone elimination of the overgrowth (against papers 2 and 10). Because diets are widely used but lack strong definitive validation for eliminating the condition compared to antimicrobial approaches, the verdict is CONTESTED.
