What the rows share
From the rowsThe best-graded row, grade D, is a crossover trial of 20 people (2022) and found an improvement.
The rows run from 8 to 20 people, published from 1997 to 2022: 2 single studies.
The rows
2 improved- DGrade DGlucose, insulin and gut hormones after a large dose · Improved
Crossover RCT · n 20 · 2022 · Healthy volunteers
50 g single dose · Single test sessions
Xylitol had only minimal effects on glucose and insulin and raised the gut hormones CCK and PYY. It also increased blood flow in the hypothalamus on brain imaging, which glucose did not.
- DGrade DBlood glucose and insulin rise compared with glucose · Improved
Crossover RCT · n 8 · 1997 · Healthy, non-obese men
25 g single dose · Single test sessions
Glucose, insulin and C-peptide rose less after xylitol than after glucose. With glucose set at 100, the glycaemic index of xylitol was 7. No reactive low blood sugar followed xylitol, unlike glucose.
