Xylitol: anybody have any problems with this stuff?

Below, I quoted some stuff I found on the Sugar substitute called Xylitol. It tastes pretty good. I'm wondering if it's too good to be true? Any problems? (By the way, I know it's a long weekend and don't expect anybody to be around...)

" Although xylitol tastes and looks exactly like sugar, that is where the similarities end. Xylitol is really sugar's mirror image. While Sugar wreaks havoc on the body, xylitol heals and repairs. It also builds immunity, protects against chronic degenerative disease, and has anti-aging benefits. Xylitol is considered a five-carbon sugar, which means it is an antimicrobial, preventing the growth of bacteria. While Sugar is acid-forming, xylitol is alkaline enhancing. All other forms of sugar, including sorbitol, another popular alternative sweetener, are six-carbon sugars, which feed dangerous bacteria and fungi.

Approved by the U.S. Food and Drug Administration (FDA) in 1963, xylitol has no known toxic levels. The only discomfort that some sensitive people may notice initially when. taking large amounts is mild diarrhea or slight cramping.

Since the body makes xylitol daily, as well as the enzymes to break it down, any discomfort usually disappears within a few days as the body's enzymatic activity adjusts to a higher intake.

Xylitol has 40% fewer calories and 75% fewer carbohydrates than sugar and is slowly absorbed and metabolised, resulting in very negligible changes in insulin. About one-third of the xylitol that is consumed is absorbed in the liver. The other two-thirds travels to the intestinal tract, where it is broken down by gut bacteria into short-chain fatty acids.

Xylitol looks, feels, and tastes exactly like sugar, and leaves no unpleasant aftertaste. It is available in many forms. In its crystalline form, it can replace sugar in cooking, baking, or as a sweetener for beverages. It is also included as an ingredient in chewing gum, mints, and nasal spray. "
