What Is Oligofructose?

Oligofructose is a type of soluble fiber found naturally in various fruits and vegetables. It belongs to a group of carbohydrates called fructooligosaccharides (FOS).

As a prebiotic, oligofructose promotes the growth of beneficial gut bacteria. It passes through the digestive system undigested until it reaches the colon.

In the colon, oligofructose ferments and produces short-chain fatty acids. These fatty acids provide energy for the cells lining the colon and support digestive health.

Oligofructose has a mildly sweet taste, making it useful as a low-calorie sweetener in food products. It’s about 30-50% as sweet as table sugar.

Chemically, oligofructose consists of fructose molecules linked together in short chains. These chains typically contain 2-10 fructose units.

Oligofructose is classified as a FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols). Some individuals may experience digestive discomfort when consuming large amounts.

Common sources of oligofructose include:

• Chicory root
• Jerusalem artichokes
• Onions
• Garlic
• Bananas

Food manufacturers often add oligofructose to products to increase fiber content or as a sugar substitute.
