We gave healthy volunteers a typical drink with xylitol to see how high the levels would get and they went up 1,000-fold. - Stanley Hazen
First, the team checked overnight fasting blood samples from participants to measure their xylitol levels. Then, over three years, the researchers found that one-third of participants with the highest levels of xylitol in their blood were more likely to suffer a cardiovascular event.
The researchers also looked at xylitol's effects in the laboratory, focusing on its impact on platelets. Mice that received xylitol injections exhibited significantly faster clotting.
