  1. Prebiotic

    Prebiotics are non-digestible food ingredients that stimulate the growth and/or activity of bacteria in the digestive system in ways claimed to be beneficial to health. They were first identified and named by Marcel Roberfroid in 1995. As a functional food component, prebiotics, like probiotics, are conceptually intermediate between foods and drugs. Depending on the jurisdiction, they typically receive an intermediate level of regulatory scrutiny, in particular of the health claims made concerning them. Roberfroid offered a refined definition in the 2007 Journal of Nutrition stating: A prebiotic is a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the gastrointestinal microflora that confers benefits upon host well-being and health" Additionally, in his 2007 revisit of Prebiotics, Roberfroid stated that only two particular prebiotics then fully met this definition: trans-galactooligosaccharide and inulin. Other authorities also classify fructooligosaccharide and lactulose as prebiotics. Mannan Oligosaccharides have been termed as prebiotics but would more correctly be termed immunosaccharides Researchers now also focus on the distinction between short-chain, long-chain, and full-spectrum prebiotics. "Short-chain" prebiotics, e.g. oligofructose, contain 2-8 links per saccharide molecule and are typically fermented more quickly in the right-side of the colon providing nourishment to the bacteria in that area. Longer-chain prebiotics, e.g. inulin, contain 9-64 links per saccharide molecule, and tend to be fermented more slowly, nourishing bacteria predominantly in the left-side colon. Full-spectrum prebiotics provide the full range of molecular link-lengths from 2-64 links per molecule, and nourish bacteria throughout the colon, e.g. Oligofructose-Enriched Inulin. The majority of research done on prebiotics is based on full-spectrum prebiotics, typically using OEI as the research substance.
