Erythritol
Typical portion
- Any typical portion
Erythritol is Low FODMAP, a sugar alcohol your body absorbs before it can ferment in the gut.
- Unlike sorbitol and mannitol, erythritol is taken up in the small intestine rather than reaching the gut bacteria that cause trouble, so it stays low FODMAP at a typical portion.
It is a handy sweetener for baking or drinks, though blends that mix it with other sugar alcohols can change the picture, so check the label.
Why erythritol is rated low
Erythritol is rated low FODMAP, and the rating is estimated from what the sweetener is rather than from a weighed serving, which is why the ladder is qualitative and reads Any typical portion: LOW. Erythritol is a sugar alcohol, but it parts company with the others because it is taken up in the small intestine rather than travelling on to the gut bacteria that ferment the rest. The catch is that erythritol very rarely arrives on its own. It is usually one name in a list, and the other sugar alcohols it is blended with behave nothing like it.
What changes your risk
- Blends are the real question Erythritol is often mixed with maltitol, xylitol, sorbitol or isomalt to soften its cooling aftertaste and improve how it bakes. Those are not low FODMAP, and a blend is only as good as the worst name on the list, so read the ingredients rather than the front of the pack.
- "Sugar-free" is the flag to look for Sugar-free gum, mints, boiled sweets, chocolate, protein bars and some diet drinks are the products most likely to be sweetened with sugar alcohols, and the nutrition panel usually says "polyols" without naming which one. The ingredient list is the only place that tells you.
- Quantity of any sugar alcohol Sugar alcohols in quantity loosen the bowels and cause wind in people with no IBS at all, which is why packets carry a laxative warning. That is worth knowing even where the FODMAP rating is not the issue.
- What the erythritol is sweetening A low FODMAP sweetener does not make the product low FODMAP. Keto and low carb bars built around chicory root fibre or inulin, biscuits made with wheat flour, and bars studded with dried fruit all carry their own load regardless of how they are sweetened.
- The rest of the meal A low rating is per serving, not per sitting. A sweetened drink, a sugar-free dessert and a snack bar in the same afternoon add up as a total, and it is the total that matters.
What else works
When erythritol is not available or a blend rules a product out, table sugar, maple syrup and rice malt syrup are the dependable low FODMAP sweeteners for baking, drinks and sauces. The ones to leave alone are the sugar alcohols erythritol gets confused with: sorbitol, mannitol, xylitol, maltitol and isomalt, along with anything sold as sugar-free gum or mints. Honey, agave syrup and high fructose corn syrup are not substitutes either. Inulin and chicory root fibre often appear in the same products as a bulking agent, and they are worth avoiding too.
How to keep it low
Read the ingredient list rather than the marketing, because "erythritol sweetened" on the front of a pack regularly means erythritol first and maltitol or xylitol a line below. The nutrition panel's polyol figure does not tell you which sugar alcohol you are getting, so the ingredient list is the only reliable place to check. Buying erythritol on its own as a granulated sweetener avoids the blend problem entirely, and it dissolves better in warm liquids than cold, so stir it into coffee or a warm batter rather than iced drinks. In baking it browns less and gives a cooling note, so it works better in fruit crumbles, custards and cheesecakes than in caramel.
Common questions
is erythritol low fodmap
Yes. Erythritol is rated low FODMAP at Any typical portion, a rating estimated from what the sweetener is rather than from a weighed serving, because it is absorbed in the small intestine rather than reaching the gut bacteria that ferment other sugar alcohols.
is erythritol the same as xylitol or sorbitol
No, and that difference matters. They are all sugar alcohols, but xylitol, sorbitol, maltitol, mannitol and isomalt are not low FODMAP, while erythritol is, which is why a blend of erythritol with any of them is not the same as erythritol alone.
can i use erythritol during the elimination phase
Plain erythritol fits, since the guidance is Any typical portion: LOW. Check that the product is erythritol alone rather than a blend, and remember that the food it is sweetening still counts on its own terms.
why does sugar-free chocolate upset my stomach if erythritol is low fodmap
Most sugar-free chocolate is sweetened with maltitol rather than erythritol, and maltitol is not low FODMAP. Sugar alcohols in quantity also cause wind and loose stools in people without IBS, which is why those packets carry a warning.
