Home > Xylitol


 Contents
Xylitol, also called wood sugar, is a polyol used as a natural alternative sweetener and toothcare product. First derived from birch, it is probably most popular in Finland, where many sweets and candies are available in both sucrose and xylitol-sweetened varieties. The latter's market consists mostly of parents concerned about their children's teeth.

Xylitol, gram for gram, is roughly as sweet as sucrose, but contains 40% fewer calories. Its formula is C5 H12 O5, with relative mass 152.15 amu.

1 Medical Applications

1.1 Dental care

In addition to discouraging tooth decay by replacing dietary sugars, xylitol may actively aid in restoring small caries (dental cavities). Recent research confirms a plaque-reducing effect and suggests that the compound, chemically similar to table sugar, attracts and then "starves" harmful microorganisms, allowing the mouth to remineralize damaged teeth with less interruption. The United States Army, acting on this data, will soon pack xylitol-sweetened gum in MREs.

1.2 Diabetes

Xylitol is a low- calorie alternative to table sugar ( sucrose) (approximately 40% fewer calories), and is absorbed more slowly than sugar; thus it doesn't contribute to a rapid rise in blood glucose and the resultant insulincarbon; green: oxygen; blue: nitrogen; pink: sulphur.

1.3 Osteoporosis

Xylitol also appears to have potential as a treatment for osteoporosisOsteoporosis is a disease of bone in which the amount of bone is decreased and the strength of trabecular bone is reduced, cortical bone becomes thin and bones are susceptible to fracture. It is defined according to the bone mineral density (BMD) as measu. A group of Finnish researchers have found that dietary xylitol prevents weakening of boneFor other uses of the word "bone", see bone (disambiguation).

1.4 Ear infection

Studies3 have shown that xylitol chewing gum can help prevent ear infections (acute otitis mediaOtitis media (also known as glue ear is an inflammation of the middle ear, usually associated with a buildup of fluid. The fluid may or may not be infected. There are several kinds of otitis media: Acute otitis media is an infection that produces pus, flu).

2 Health Concerns

Xylitol, like most sugar alcohols, can have mild laxativeA laxative is a preparation used for the purpose of encouraging defecation, or the elimination of feces. Laxatives are most often taken in response to constipation. They are also sometimes used before medical procedures. They are often abused by bulimics effects at high doses. It has no known toxicity; people have consumed as much as 400 gramsFor other meanings of gram see gram (disambiguation). The gram (also spelt gramme is a unit of measurement of mass, and is defined in the SI system of units as one thousandth of a kilogram. See 1 E -3 kg for comparisons with other masses. The symbol for g daily for long periods with no ill effects.
