Clinical Trial Summary

The aim of this project is to evaluate metabolite profile after consumption of three types of coffee differing in type of bean, degree of roasting and preparation method. Metabolite profiles will be evaluated after a) a single dose b) 3-day consumption. The study will be carried out as a three-way cross-over design with three different types of coffee. Wash-out periods where participants consume their habitual diet are implemented between all intervention periods. The first day of intervention (single dose) includes postprandial measurements during 13 hours.
