Sensitivity notes
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 isomalt
Isomalt (E953) starts life as ordinary table sugar. Manufacturers split the sucrose enzymatically and hydrogenate the halves, ending up with a roughly equal mix of two disaccharide alcohols. That structure is exactly why pastry chefs prize it: isomalt barely picks up moisture from the air and resists recrystallising, so pulled and blown sugar showpieces stay glassy for days and hard candy stays clear instead of going sticky. It is also why our data grades it high FODMAP and high polyol. Human digestive enzymes cannot cleave the hydrogenated bond, so most of a dose walks straight into the colon. Everything else on this page is clean: no gluten, no lactose, no dairy protein, no histamine, no salicylates, no oxalate.
Watch for
- Graded high on FODMAPs and polyols.Isomalt is largely indigestible by design, which is the point for calorie labelling and the problem for your gut.
- Sugar-free hard candy, mints, lozenges and cough drops are the usual dose, and they are deceptively easy to overshoot because each piece looks trivial.
- EU labelling requires a warning that excessive consumption may produce laxative effects on any food containing more than 10 percent polyols.A sugar-free boiled sweet is often almost entirely polyol.
- Graded poorly for SIBO fermentation, since anything that reaches the lower gut intact is substrate for bacteria that should not be there.
- Oral bacteria cannot ferment isomalt, which is why it is sold as tooth-friendly and carries a genuine dental claim.That tells you nothing about how the rest of your digestive tract will handle it.
