Prebiotics

Prebiotics are usually in the form of oligosaccharides, which may occur naturally but can also be added as dietary supplements to foods, beverages, and infant formula. Chicory root is considered the richest natural source. Prebiotics are considered functional foods, so-called because they provide health benefits that go beyond basic nutrition. Although they are also available in supplement form, prebiotics occur naturally in a number of common foods with high fiber content.
