This is an interventional, open-label, single-group, bioavailability postprandial study. The aim of the study is to evaluate the bioavailability of phenolic compounds of a beverage prepared with Cretan carob powder of the Imera cultivar in healthy individuals after consumption.

This is an interventional, open-label, single-group, bioavailability postprandial study. The aim of the study is to evaluate the bioavailability of active constituents of a beverage with carob powder in healthy individuals after consumption. Fifteen apparently healthy male adults of normal body fat mass (non-obese) will be enrolled based on certain inclusion and exclusion criteria. After enrollment, the volunteers will undergo a medical and dietary assessment and will be instructed to follow a low-phytochemical diet (washout) for five consecutive days, excluding from their diet sources of phytochemicals, i.e., fruits, vegetables, legumes, coffee, tea. Compliance with the low-phytochemical diet will be assessed with a 24 h recall during and at the end of the washout period. On the day of the experiment following washout, volunteers will be given a carob beverage (blood samples will be collected 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0h postprandially). Time intervals 0-6h will be used for LC-ESI-MS/MS approach in order to identify putative polyphenol metabolites related to carob consumption.
