Editorial summary
This summary is editorial and is not part of the clinical review. Ratings above are unchanged.
What sorbitol is
Sorbitol is a sugar alcohol, also called a polyol. It occurs naturally in fruits such as apples, pears, cherries, peaches and plums, and it is also made commercially for use as a sweetener and to keep foods moist. It is common in sugar-free gum, mints and sweets, diabetic and reduced-sugar products, some baked goods, liquid medicines, cough syrups and toothpaste. On European labels it may appear as E420.
How it affects digestion
Sorbitol is absorbed slowly and incompletely in the small intestine. The part that is not absorbed draws water into the gut and is then fermented by bacteria in the colon, which can cause bloating, gas, cramping and loose stools. Monash University, which tests foods for FODMAPs, lists sorbitol among the polyols that are high FODMAP and notes that these effects can occur whether or not the polyol is absorbed. Sugar-free gums and mints often carry a warning that heavy use may have a laxative effect.
Why the rating differs by condition
For inflammatory bowel disease our rating is Avoid during a flare and Limit in remission, because water drawn into the gut and fermentation can make diarrhea and cramping worse. For Hashimoto's, Graves', rheumatoid arthritis, multiple sclerosis and lupus it is Usually OK. For insulin-dependent diabetes it is also Usually OK. It is widely used in reduced-sugar and diabetic products, but the other carbohydrates in those products still count, so read the total carbohydrate line.
Reading a label
Look for sorbitol, E420 and sorbitol syrup, and for related polyols such as mannitol, maltitol, xylitol, isomalt and lactitol, which share the same digestive effects. Chewing several pieces of sugar-free gum a day, or eating a bag of sugar-free sweets, can add up quickly. Liquid medicines are easy to overlook, so ask your pharmacist whether a sorbitol-free version exists if you notice symptoms.
In short
In short, sorbitol is a sugar alcohol that can cause bloating and diarrhea in larger amounts, which is why it is rated Avoid in an IBD flare and Limit in remission, and Usually OK for the other conditions on this site.
