Effect of Different Concentrations of Xylitol and Erythritol on Gut Peptide Release and Gastric Emptying in Humans

September 14, 2018 updated by: University Hospital, Basel, Switzerland

Effect of Different Concentrations of Xylitol and Erythritol on the Release of Gastrointestinal Peptides and on Gastric Emptying Rates in Healthy Normal Weight Humans

Xylitol and erythritol have become increasingly popular as sugar substitutes in the food industry. Both substances are freely available. While glucose ingestion stimulates satiation hormone secretion in the gut and slows down gastric emptying, artificial sweeteners such as aspartame, sucralose and acesulfame-K have no such effect. However, acute intake of 50g xylitol or 75g erythritol in 300mL tap water leads to a marked increase in the satiation hormones and induces a significant retardation in gastric emptying. The concentrations used to Show this effect were rather high (50g xylitol and 75g erythritol) and led to bloating and diarrhea in 60-70% of all subjects two hours after administration. The aim of the present study is to find an effective concentration of xylitol and erythritol still stimulating satiation hormone release without any gastrointestinal adverse events.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
