Overview
Childhood and adolescence are crucial periods for prevention of obesity, as obese children are five times more likely to be obese at adulthood than lean children. To this purpose, sugar consumption should be reduced. The sugar alcohol erythritol is increasingly popular as sugar substitute in the food industry and is also recommended to diabetic patients. The substance is freely available. Recent acute studies show that erythritol has a positive influence on satiation and gastric emptying without affecting insulin and plasma glucose. In this trial, the investigators aim to assess the effect of a chronic intake of erythritol versus sucrose on insulin resistance in healthy adolescents.
EryClot-Pilot:
Erythritol is also produced by the human body and possibly elevated erythritol levels in the blood are an indication of an increased risk of cardiovascular disease, obesity or diabetes in the future.
In a recently published study, a possible effect of erythritol on blood clotting function was described. In this in vitro experiment, increased blood clotting was observed when erythritol was added to clotting cells (platelets) in the test tube. Studies in humans on blood coagulation after administration of erythritol are missing so far.
With a pilot study, the investigators study whether erythritol is detectable in the blood after administration of glucose and fructose. Furthermore, the erythritol level in the blood and a possible effect on the blood coagulation function after administration of erythritol will be investigated.
These preliminary tests serve to clarify the data situation so that further studies can be based on them.
Description
This trial aims to assess the effects of the daily intake of an erythritol-sweetened beverage over 5 weeks on insulin resistance, glucose tolerance and metabolism as well as on gut microbiota. Moreover, this study will also assess the effect of the above-mentioned intervention on food intake, body composition and gastrointestinal tolerance in this population.

The aim of this pilot study is to investigate whether erythritol is detectable in the blood after administration of glucose and fructose. Furthermore, the erythritol level in the blood and a possible effect on the blood clotting function after administration of erythritol will be investigated.
