                                According to research published by the National Institutes of Health, xylitol, a low-glycemic sugar alcohol, causes only a small, delayed rise in blood glucose and insulin levels. However, the key question remains: is that small effect enough to break a fast? The answer largely depends on the type of fast you are following and your specific health goals.
