SIBO Diet & Nutritional Strategies

Manage bacterial fermentation, control gastrointestinal symptoms, and protect the mucosal barrier through evidence-based dietary interventions.

Fermentation Control

The low-FODMAP diet limits rapidly fermented short-chain carbohydrates. It eases gas and bloating for many people but does not clear SIBO, and is meant to be temporary.

Low-Carb & Keto

Cutting carbohydrates reduces gas, and a low-carb diet did about as well as low-FODMAP in an IBS trial. Very high fat intake and low fiber can backfire with SIBO.

Fermented Foods & Histamine

Kefir and sauerkraut have not been studied in SIBO. Lactose, fermentable fibers and histamine can worsen symptoms, so a slow reintroduction after treatment is the cautious approach.
