Although the question vanessa branch seems absurd not to get the birch sugar, chemical name among the main components of birch (Betula) vanessa branch species xylitol (xylitol in English). Why it was named after this tree, and it really is so beneficial to use, as they say in the commercials?
The first xylitol Emil Fischer (who later received the Nobel Prize, but not why) was produced bükkfaforgácsból. With him around the same time the French chemist Bertrand also produced tölgyfaforgácsból the material. Thus, xylitol "birth" did not have much to do with the birch tree. The name of the compound, however, suggest that wood was obtained: the Greek word xyl (on) is a tree, the par-ticipants and ending vanessa branch suggests that substances include sugar alcohols are concerned.
Xylitol can be produced from birch, in fact it is a good resource of the raw material because it contains a large amount vanessa branch of wood xylan. The xylan, which is a complex made up of base units xylose sugar xylose broken down (hydrolyzed), this will result in reduction of xylitol. Furthermore many fruits and vegetables contain xylitol, xylose but industrial scale production more economic.
Nowadays vanessa branch most birch, corn stalk, bagasse, and the residue of the prepared since these raw materials contain high amounts of xylose. The forums on the Internet live "polemics" about going to the corn-derived or obtained from birch xylitol is the better. This debate, of course, makes no sense if the product contains pure xylitol, it does not matter, vanessa branch what is produced, because this simple pentavalent sugar alcohol has no memories ... Because of the genetically modified vanessa branch maize fear many people (especially in America) xylitol produced wood preference, but its not too much rationality, because of genetic engineering, in particular protein crops production may xylitol structure will have absolutely no influence.
Why and why it has become fashionable to benefit from the consumption of xylitol? Primarily because, although pleasant, vanessa branch utóízmentes sweet taste, the calorie vanessa branch content of about 70% of the répacukorénak, the blood sugar level is much less increase than sucrose (cane sugar, granulated sugar, chemically sucrose) or glucose (the latter glycemic index of 70 or 100, xylitol ca. 10). In case of consumption of calories is lower than that of sucrose, vanessa branch non-toxic, more than 10 g per day (this is higher than average quantities used in sweetening) for several years with no evidence of adverse effects. This - in diabetics and dieters terms - in itself would be sufficient vanessa branch to be popular preferred sweetener but also a number of other positive effects have also.
Thoroughly examined the effect of tooth decay and tartar formation inhibitory activity, vanessa branch which various studies carried out on humans justified. Overall, we can say that xylitol ingestion vanessa branch of 1-67 grams per day reduced the risk of tooth decay by 30-85%. One of the biggest study (it was conducted in 1970 called. Turku test) in the diet of sucrose entirety xylitol is replaced, and the test significantly less tooth decay was observed compared to controls (who received a normal diet) for 2 years. The long-term xylitol consumed an average of 50 grams per day amount is not documented adverse effects.
The reason for the anti-caries effects have not yet been fully explored, there are several theories about this. One is that the effect of xylitol is that live in the mouth, sugar acid-producing microorganisms are not able to break down. Others say - and this is supported by experimental vanessa branch data - a sugar alcohol inhibits the growth of bacteria that cause decay. The condition of the two effects mentioned above, the xylitol permanently in contact with microbes in the oral cavity. Ideally suited for this purpose xilittartalmú chewing gum. But surprisingly, not only observed in the case of a positive effect rágógumizók: among similarly low (30 to 45% in the control obtained rare) decay xilittartalmú candy consumers. It was unexpected that the xylitol consumers will be the increased remineralisation (the mineral content will increase) was observed, and surprisingly, tooth decay even years after the tests completion was less common vanessa branch among those who were supplemented with xylitol food / chewing vanessa branch gum. It is, however, that pre-caries effect of xylitol sorbitol (a sugar alcohol related structure, is also used as a sweetener) compared to significant, suggesting that the effect is not yet fully explored, vanessa branch explained more or less specific effects.
In addition to the beneficial effects are duly supported by some little convincing evidence of use as well. Although multiple promising studies are underway in the xylitol, there is still some way to use solution orröblítésre. Better yet if we do not do more than what has been proven (and not a few): a low-calorie, low blood sugar lift, you're going to
