- Complete elimination for 30 days gives the clearest picture
- Watch for hidden nightshades in spice blends and sauces

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.
