Xylitol is a natural sweetener found in many fruits and vegetables such as strawberries, raspberries, plums or cauliflowers. Discovered in 1891 by Emil Fischer, at the industrial level it is usually extracted from the bark of birch or corn cobs and has spent years languishing as a product for diabetics. Now, for several years, it has become an attractive alternative to sugar consumption and an ally for the protection of our teeth. The main advantages are:

Prevention of tooth decay. By reducing acid production caused by cariogenic bacteria it promotes a less acidic environment between tooth and plate. Therefore there is a lower risk to desmineralise the tooth structure, reducing decay between 30% and 60%.

Low in calories. Compared to table sugar, Xylitol has 40% fewer calories and 75% fewer carbohydrates. This makes it a very useful alternative for those who follow a healthy diet or for people who should limit consumption of sugar.

Glycemic index. With an amount of 7 in the measurement chart of the glycemic index in food (the same as in a lettuce) it shows a huge difference comparing the 99 of sugar. This means Xylitol is suitable for consumption by diabetics.
