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 maltitol
Maltitol is a sugar alcohol, and it is graded a high polyol and high FODMAP trigger. It is the bulk sweetener that gives sugar free chocolate, gummies, mints and protein bars their body and mouthfeel, and it is the specific ingredient behind the famous sugar free sweet horror stories. Only part of a maltitol dose is broken down and absorbed in the small intestine. The remainder arrives in the colon still intact, drags water in with it by osmosis and is fermented by gut bacteria, which produces gas, cramping, urgency and loose stools within a few hours. This is well enough established in law that EU labelling rules make foods with a meaningful added polyol content carry the phrase "excessive consumption may produce laxative effects". Maltitol is also a weak choice for blood sugar: its glycaemic index sits far above erythritol, which is close to zero, so the sugar free claim on the front of the pack says less about your glucose response than the name suggests.
Watch for
- Graded high on polyols and high FODMAP overall, which makes it the single most common explanation for bloating, wind and loose stools a few hours after eating something labelled sugar free
- Poor for low fermentation and SIBO approaches, because the unabsorbed fraction is fermented in the colon rather than passing through inertly
- The dose that tips people over is smaller than expected.A modest handful of sugar free chocolates or gummies can do it, and because the delay runs to several hours the symptoms usually get blamed on the meal that came before
- It hides under several names.Look for maltitol syrup, hydrogenated glucose syrup, hydrogenated maltose or E965, and note it is often the bulking agent even in products that advertise stevia or sucralose as the sweetener
- Glycaemic index is far higher than erythritol and it still carries roughly half the calories of sugar, so it is not a free pass on either glucose or energy
