Naturally Sweet Xylitol is available in a 500g resealable pack as a fine grade icing sugar. Great for those wanting to have some icing on their cake! Ideal for diabetics. Substitute for sugar on a 1:1 basis. Naturally Sweet Xylitol is made from a product originally derived from birch bark but is now usually obtained from corn. It modifies the saliva in your mouth so that eating meals, desserts and candies flavoured with Xylitol not only do not cause cavities but prevents cavities by promoting the remineralisation of tooth enamel. BUT AS IMPORTANTLY, every teaspoon of Naturally Sweet Xylitol also contains 40% fewer calories than sugar! It is also so slowly absorbed that it has almost no effect on blood sugar levels for people who have diabetes. Note: This product has a 4% corn starch content.
