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 lactitol
Lactitol is made by hydrogenating lactose, and the name puts people off for the wrong reason. It contains no lactose. Our data grades it clean on lactose and clean on dairy protein, and EU law agrees: lactitol is one of the very few milk-derived ingredients specifically exempted from allergen declaration under Regulation 1169/2011. What it actually is, is a polyol, graded high FODMAP and high polyol. It is potent enough that a 20 gram dose is licensed as a prescription laxative for chronic constipation. That is the honest dose response for anyone eating sugar-free chocolate or baked goods: the amount that treats constipation is the amount that can hide in an afternoon of snacking.
Watch for
- Graded high on FODMAPs and polyols.No human enzyme splits the bond, so lactitol arrives in the colon whole, holds water osmotically and then gets fermented.
- The dose response is unusually well documented because lactitol is a licensed medicine.Around 20 grams a day is the therapeutic laxative dose for chronic idiopathic constipation, so several sugar-free sweets or a large bar of sugar-free chocolate is not a trivial amount.
- It carries no lactose and no milk protein, so lactose intolerance and cow milk protein allergy are not the mechanism.If lactitol bothers you, it is the polyol doing it, not the dairy origin.
- Graded poorly for SIBO fermentation, which matters more than the raw dose if you have small intestinal bacterial overgrowth.
- It is still milk-derived in origin even though it needs no allergen declaration.Strict vegans and people avoiding all dairy-sourced ingredients on principle will want to know that, because the label will not tell them.
