Sensitivity notes

Why fodmaps food checker matters

FODMAPs are fermentable carbohydrates that can cause digestive distress in sensitive individuals. They include fructose, lactose, fructans, galactans, and polyols. These sugars are poorly absorbed in the small intestine and ferment in the colon, potentially causing bloating, gas, and discomfort.

Start with a 2-6 week elimination phase, removing all high-FODMAP foods
Keep a detailed food and symptom diary to track your reactions
Reintroduce one FODMAP group at a time to identify your specific triggers
Remember that threshold varies - you may tolerate small amounts
Work with a dietitian trained in the low-FODMAP diet for best results

What to know about mannitol

Mannitol is graded high FODMAP and high polyol in our data, and it is the polyol most people eat without ever hearing its name. Monash keeps sorbitol and mannitol apart because the food lists barely overlap: sorbitol belongs to stone fruit, apples and pears, while mannitol is the one in mushrooms, cauliflower, celery and snow peas, plus the E421 dusted onto sugar-free gum and pressed into tablets. Our data collapses both into a single polyols column, so a high polyols grade on this page means mannitol specifically. On everything else it is clean: no histamine, no salicylate, no oxalate, no gluten, no lactose, no free glutamate. The malabsorption is the entire story.

Watch for

Graded high on FODMAPs and polyols.Only part of a mannitol dose is absorbed in the small intestine, so the remainder drags water into the bowel and then ferments in the colon: bloating, cramping and loose stools within hours.
This is the polyol behind mushrooms, cauliflower, celery and snow peas.People who fail a cauliflower or mushroom challenge on a low FODMAP reintroduction are usually reacting to mannitol, not to fructans.
US labels must carry the statement "Excess consumption may have a laxative effect" when foreseeable daily intake reaches 20 grams of mannitol (21 CFR 180.25).Treat that as a regulatory floor, not a personal threshold: sensitive guts react well below it.
Graded poorly for SIBO fermentation.Anything that reaches the colon undigested feeds an overgrown small intestine on the way, and mannitol is fermentable by definition.
Scan for E421 rather than the word mannitol.It also appears as an anticaking agent and as a filler in medicines and supplements, which is an easy hidden dose to miss when you are logging food only.
