Xylitol Reverses Bone Loss in Old Animals

In this recent study, 24 rats were given Xylitol in their diet for twenty months. At the end of this time, they were euthenized with carbon dioxide. The bone mineral content and volume of the bones was evaluated by several sophisticated analytical techniques.

The tibial (lower leg bone) density of control animals averaged 1.560 g/mm3, while the density of the tibias of the Xylitol-fed animals averaged 1.725 g/mm3, indicating a Xylitol-induced increase of bone density of nearly 10%.

The authors stated that Xylitol consumption resulted in significant protection against aging-related loss of bone, and The preserved bone volume indicates an anabolic and/or anti-catabolic effect…caused by Xylitol. They concluded: A continuous moderate dietary Xylitol supplementation leads to an increased bone volume and to an increased bone mineral content in the long bones of aged rats. This indicates a Xylitol-induced protection against aging-related osteoporotic changes.

Xylitol Mechanisms and the Neuroendocrine Theory of Aging – Another Receptor Sensitizer?

The scientists speculated that xylitol’s bone density-enhancing properties were due to its ability to promote intestinal absorption of calcium. They pointed out that calcium absorption is impaired with aging. They believe that this is due to an age-related intestinal resistance to 1,25 dihydroxy vitamin D3, and by an age-related decrease in intestinal vitamin D receptor concentrations. I think this is similar to the age-related loss of receptor sensitivity and associated hormonal resistance observed in many other receptor systems. (9)

The scientists proposed that Xylitol’s efficacy in enhancing calcium absorption and utilization may be independent of the apparent vitamin D resistance. It may be the mineral absorption- and utilization-enhancing effects of Xylitol combined with its H. pylori-killing effects that result in Xylitol’s ability to reduce the number and size of cavities. Some cavities have even tended to fill in. Of course, it may be that Xylitol acts as a vitamin D3 receptor sensitizer, enhancing the effects of vitamin D (see Table 2).
