Xylitol was originally used as a natural alternative to sugar with its 1:1 sweetness ratio. It has virtually no effect on blood sugar and insulin levels. It also has 40% fewer calories than sugar. Xylitol also moistens and soothes skin by pulling water to the skin surfaces. One of the greatest benefits of xylitol is how it interacts with bacteria. This is two-fold. Firstly, xylitol is non-fermentable, meaning bacteria can’t use it in their metabolic processes. This results in bacteria not being able to thrive or produce their byproduct, harmful acids. Secondly, xylitol has an anti-adhesive quality. This unique characteristic prohibits bacteria from adhering to cell tissue. Because bacteria must adhere to the tissue in order to flourish, xylitol is able to reduce their effect without using harmful chemicals or drugs.
