Wine Implementation for Surgical Recovery Enhancement

Subjects in the intervention arm (SoC+WISE) will be assigned to consume exclusively during meals one glass (around 150 ml at lunch and 150 ml at dinner) of red wine containing ethanol (˜13% EtOH v/v) with a high content of phenolic compounds (800 mg of Gallic acid equivalent) both for woman and men. Total polyphenolic contents and antioxidant activity (Folin-Ciocalteu method with calibration curve in gallic acid), antioxidant/radical scavenger capacity \[DPPH (2,2-diphenyl-1-picrylhydrazyl) test\] and phenolic profiles \[HPLC (High Performance Liquid Chromatography)/DAD (diode-array detector) /ESI-MS (Electrospray Ionisation Mass Spectrometry) analysis\] will be performed for wine selection for the clinical trial.
