Why low fermentation food checker matters
SIBO (Small Intestinal Bacterial Overgrowth) diets focus on reducing fermentable foods that feed bacteria in the small intestine. Low-fermentation foods help manage symptoms like bloating, gas, and abdominal discomfort.
- Low-fermentation eating reduces food for overgrown bacteria
- Meal spacing (4-5 hours) allows the MMC to clear the gut
- Avoid grazing - structured meals are better
- Some find the elemental diet helpful under medical supervision
- Address underlying causes with your healthcare provider

What to know about tofu
Tofu is clean on histamine, gluten and lactose, but it is high in oxalate and high in nickel, and because it is made from soybeans it is a recognised EoE and elimination-diet trigger. Its FODMAP status is texture-dependent: firm and extra-firm tofu are low FODMAP because the GOS-rich liquid is pressed out, while silken tofu holds more and sits higher. So the usual reasons tofu bothers people are oxalate and nickel, not gluten.
Watch for
- High in oxalate, especially calcium-set tofu, which can be a problem if you are prone to kidney stones or oxalate-related symptoms
- High in nickel, so regular tofu-heavy meals can add up for people with systemic nickel allergy
- Firm and extra-firm tofu are low FODMAP; silken tofu is higher, so swap the texture before you cut it out
- Soy is a top EoE and six-food-elimination trigger, so tofu comes off the list on those protocols
