Tooth plaque inevitably builds up naturally. The accumulation can increase bacteria behind the eardrum and cause middle ear infections, otitis media (AOM).
A 2016 systematic review found evidence that chewing foods containing xylitol can reduce the occurrence of AOM from 30 to 22 percent among healthy children.
Due to its low GI, xylitol is also a weight loss-friendly sugar substitute. A 2015 study revealed that xylitol had significant blood glucose-lowering effects in rats that ate high-fat diets.
Xylitol has antioxidant properties. A 2014 study showed Diabetic rats who ate xylitol produced higher amounts of glutathione. This is an antioxidant that counteracts the harmful effects of free radicals.
