  Purpose

Coffee contributes to a large extent to our daily intake of phenolic compounds which have been associated with potential health benefits. A study by Richelle et al. (2001), using an LDL oxidation assay, showed that phenolic compounds in coffee possessed antioxidant activity which varied depending on the coffee bean source and the degree of roasting. Little is known about the bioavailability of phenolic compounds from coffee at various roasting degrees. Therefore, further human studies are required in order to demonstrate the absorption, and bioavailability of metabolites that may also be efficient in vivo.

The main objective of this clinical trial is to investigate the possible difference in the bioavailability of chlorogenic and phenolic acids from coffee at various roasting levels.

Detailed Description:

Coffee contributes to a large extent to our daily intake of phenolic compounds which have been associated with potential health benefits. A study by Richelle et al. (2001), using an LDL oxidation assay, showed that phenolic compounds in coffee possessed antioxidant activity which varied depending on the coffee bean source and the degree of roasting. Little is known about the bioavailability of phenolic compounds from coffee at various roast levels. Therefore, further human studies are required in order to demonstrate the absorption, and bioavailability of metabolites that may also be efficient in vivo.

The main objective of this clinical trial is to investigate the possible difference in the bioavailability of chlorogenic and phenolic acids from coffee at different roast levels.

After medical examination and approval, subjects will be randomly assigned to one of the four coffee treatments. Each study period correspond to the ingestion of one the treatments and study periods are separated by a one week washout period. Blood will be taken as a time course for 24h while urine will be collected for 30h. Investigators are also blinded with respect to the dose and the treatment given to the subjects.
