Summary

Dietary fiber is well known to have health promoting effects, including reduced blood glucose and cholesterol levels. Bread is the most important source of dietary fiber in the Norwegian diet. Production of bread has changed from the traditionally use of sourdough, to yeast (Saccharomyces cerevisiae) as the dominating leavening agent in modern industrial production. Sourdough naturally contains bacteria, and through the fermentation process these bacteria release several components that are not found in modern bread using yeast. It has been shown that sourdough may have positive health effects, including on blood glucose regulation. The aim of the project is to investigate if intake of sourdough may give positive health effects compared to beard with yeast.

Detailed description

The investigators aim to include approximately 20 participants in this randomized controlled double-blind cross-over study lasting for 5 weeks. All participants will be given bread baked with yeast for a 2 weeks run-in period. The participants will then be randomly assigned to either 1 week intervention with bread baked with yeast or sourdough, before a 1 week wash-out period with yeast bread. During the last 1 week intervention period the participants starting with bread baked with yeast will be given sourdough and vice versa. Questionnaires (GSRS-IBS, BSC, FFQ), blood samples, and feces samples will be collected before and after the intervention periods.
