Effect of Dough Fermentation Time of Bread on the Glycaemic Index (SLOWBREAD)

October 7, 2015 updated by: Beatrice Baumer
This study evaluates the impact of dough fermentation times on the glycaemic index of the ensuing breads.

Study Overview

Detailed Description

The worldwide prevalence for non-communicable diseases (NCD) is increasing, nutrition is considered to be one of the main modifiable risk factors. An unhealthy diet leads to obesity, which is a further risk factor for NCDs. Excessive carbohydrates but also the nutritional quality of carbohydrates, can be elements defining "unhealthy diets". The nutritional quality of carbohydrates can be expressed as the glycaemic index.

Fermentation time of bread dough could affect the ensuing bread quality to such an extent that it influences ist glycaemic index. If this hypothesis is confirmed, the process of breadmaking could be optimized in order to offer healthier bread varieties on the market.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in postprandial glycemia: Glucose in capillary blood samples over 2 hours (blood samples every 15 minutes), after oral intake of bread samples or glucose-solution (reference)
Time Frame: 2 hours for each sample, 7 samples total, on non consecutive days, over 4 weeks
a drop of capillary blood will be taken every 15 minutes after ingestion of a bread sample containing 50 g of available carbohydrates
2 hours for each sample, 7 samples total, on non consecutive days, over 4 weeks
