About
During this project the effect of yeast bread and sourdough breads consumption on satiety, energy intake at subsequent meal and postprandial metabolic responses, will be investigated.
Full description
The primary aim of this study will be to evaluate the impact of an alternative starter culture that produces high levels of lactic acid on appetite regulation (subjective satiety and energy intake at the subsequent meal). The second aim will be to identify mechanistic parameters that may explain the observed effects, including glycaemic and insulin response, and gastric emptying rate. In addition, habitual physical activity levels, and mood and stress levels of the subjects will be evaluated as potential covariates of appetite regulation.
It is hypothesized that:
Sourdough breads fermented with the alternative starter culture that produce high concentrations of lactic acid will reduce glucose response via lower starch digestibility and/or slower gastric emptying rate. The reduced glycaemic response will lead to higher satiety and lower energy intake at the subsequent meal (more than 10%).
