The ingestion of a sufficiently large amount of non-digestible and/or non-absorbable sugar substitutes causes overt diarrhea. The objective is to estimate the non-effective dosage that does not cause transitory diarrhea for xylitol, lactitol, and erythritol in healthy subjects. Twenty-seven males

The aim of the present study was to compare the ability of four dietary polyols to reduce bone resorption. Urinary excretion of 3H radioactivity from [3H]tetracycline-prelabeled rats was used as a marker of bone resorption. After prelabeling, the rats were divided randomly into five groups of 10,

Previous rat caries experiments in our laboratory demonstrated an anti-cariogenic and most probably a remineralizing effect of xylitol. The purpose of the present study was to compare the caries-inhibiting property of xylitol and fluoride in drinking water. The study consisted of two experiments

In conclusion, fructose, sorbitol, and xylitol are calorie-containing non-glucose sugars that produce a lessened postprandial hyperglycemia in the absence of severe insulin insufficiency when given as pure substances. However, the day-long quantitative reduction of hyperglycemia that may result from

Hepatocytes isolated from fed, male, Sprague-Dawley rats accumulate xylulose-1-phosphate and glycolaldehyde as well as xylulose-5-phosphate when incubated with 2-20 mM D-xylulose. Fructokinase inhibitors (fructose and 1-deoxyfructose) decreased xylulose-1-phosphate and glycolaldehyde (but not

Homeopathic globules are frequently used in children as a first-line treatment. Most of these globules are coated with sugar substitutes like xylitol; these substitutes are known for their laxative effect. Our patient shows that consumption of globules coated with xylitol does not have only laxative

OBJECTIVE
Xylitol, given as 2g orally five times-a-day, significantly reduces the incidence of acute otitis media (AOM) in children. A less frequent dosing schedule, if tolerable and efficacious, would promote the more widespread use of this treatment. We sought to determine the tolerability and

Sprague-Dawley rats were fed diets containing up to 20% xylitol for 49 days. When the rats were fed a xylitol regimen intended to produce adaptation to xylitol, approximately half of the animals adapted to xylitol and remained free from diarrhea during the feeding regimen. The other half did not

Xylitol is recommended as a sugar substitute and is claimed not only to be non-cariogenic, but also to exhibit an anti-caries effect. An interesting aspect of xylitol is that it has a certain bacteriostatic effect. Xylitol is taken up by many strains of Strep mutans and Strep sanguis even if these

Rats fed a 20% xylitol diet were compared to rats fed for 6 weeks a diet of either 20% glucose, cornstarch or sucrose (plus 45% cornstarch), or the AIN-76TM diet (basal diet). There were no differences between the rats (diarrhea-free) fed xylitol and those fed the other carbohydrate sources in the
