Yes, xylitol has a very low glycemic index and does not cause rapid spikes in blood sugar, making it a common sweetener for diabetic diets.
Xylitol is a sugar alcohol (polyol) with calories (though fewer than sugar) and a cooling effect. Stevia is a calorie-free sweetener derived from a plant leaf. They have different chemical structures and metabolic effects.
Oral bacteria cannot metabolize xylitol to produce acid that causes tooth decay. Xylitol can also reduce plaque formation and strengthen tooth enamel.
