This randomized controlled crossover study evaluated the impact of chestnut flour-enriched bread on postprandial glycaemic responses in fourteen healthy adults. The results indicated that this bread significantly reduced glucose incremental area under the curve (iAUC) by 27% compared to control bread, suggesting its potential for improving glycaemic control.
Key findings
- Chestnut flour-enriched bread reduced glucose iAUC by 27% compared to control bread (p = 0.0319).
- Glucose concentrations were 16% lower at 120 minutes and 14% lower at 150 minutes after consumption of chestnut bread.
- Insulin peak time was reduced by approximately 24 minutes with chestnut flour-enriched bread (p = 0.0430).
Why it matters
Managing postprandial glycaemia is crucial for reducing the risk of cardiometabolic diseases. This study suggests that incorporating chestnut flour into bread may be an effective dietary strategy to improve glycaemic control.
