Healthline published an article by Kris Gunnars, BSc. covering all aspects of xylitol. Xylitol looks and tastes like sugar but has fewer calories and doesn’t raise blood sugar levels. Several studies suggest that it has various important benefits. Xylitol is a sugar alcohol, found in small amounts in many fruits and vegetables and is therefore considered natural. Humans even produce small quantities of it via normal metabolism. it doesn’t contain any vitamins, minerals, or protein. Unlike sugar, xylitol has negligible effects on blood sugar and insulin levels. Animal studies indicate impressive benefits for metabolic health. Xylitol can improve dental health, reduce ear and yeast infections, and has other potential health benefits. Some studies suggest xylitol may be able to protect against the effects of aging by increasing collagen production; protect against osteoporosis and feed the friendly bacteria in the gut acting as a soluble fiber and improving digestive health. Xylitol is toxic for dogs but for humans, it may cause digestive upset but is otherwise well tolerated.
