Xylitol is usually equated with birch sugar. I buy this for a long time from several different manufacturers. Only by reading the reviews I have learned that the blue Xucker not come from Finnish birch, but Chinese corn! In the small print Product Description Amazon is still a country of origin Finland, I checked on the package and, in fact - corn cobs, China. Use can for slightly more money (the dark red pack) Xucker buy, the - as generally assumed - comes from Finnish birch. The two stars are there, because xylitol per se is just great and I continue to recommend the use in principle enthusiastically. It is not as acid forming as granulated sugar and deprives the caries bacteria the food basis. If you let dissolve a teaspoon of xylitol in the mouth, you can feel how the teeth feel smooth and clean afterwards. Besides, it is the taste was just as well as sugar.
