Isomalt
AvoidSweetener
Isomalt is a sugar substitute classified as a polyol, often used in sugar-free products, but it is high FODMAP at typical serving sizes.
What is Isomalt?
Isomalt is a sugar alcohol, or polyol, derived from sugar beets and used as a low-calorie sweetener. It is commonly utilized in sugar-free products, including candies, chewing gums, and baked goods, due to its stability under heat and its ability to maintain a sweet taste without promoting tooth decay. Though it has about half the calories of regular sugar, it can cause digestive discomfort in some individuals, especially when consumed in large quantities.

Why People Avoid Isomalt
People might avoid isomalt because it is a polyol, which can cause digestive upset such as bloating, gas, and diarrhea, particularly in those with sensitive digestive systems or individuals following a low FODMAP diet. As isomalt is high FODMAP at normal serving sizes, it may trigger symptoms in people with irritable bowel syndrome (IBS) or other digestive disorders.
