Xylitol is a sugar alcohol that occurs naturally in many fruits and berries. It is often used as a sweetener substitute in foods, providing the same sweetness as refined sugars with less food energy 1. Xylitol is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food additive (21CFR172.395).
Xylitol is a non-digestible pentose sugar that passes through the upper gastrointestinal tract and is fermented by inhabitant saccharolytic microorganisms to produce by-products such as short chain fatty acids (acetate, propionate and butyrate), gases (hydrogen, methane, and carbon dioxide), and organic acids.* Xylitol supports the growth of health-promoting probiotics like Lactobacilli and Bifidobacteria by supporting the colonic microflora 2.*
