简要总结
Based on our hypothesis that orally administered resistant starch and inulin/beta glucan will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective:
To investigate the effects of an acute administration of inulin/beta glucan in combination with resistant starch on fecal and plasma acetate, as well as on fasting and postprandial substrate and energy metabolism in lean normoglycemic men and obese, prediabetic men.
