This study aimed evaluating the effect of acute consumption of juçara juice ( Euterpe edulis ) rich in anthocyanin on biomarkers of oxidative stress in healthy subjects. This cross‐over clinical trial used water as control. Eleven volunteers were evaluated 4 times, before consumption and 1h, 2h and 4h after the intake of juice or water. The parameters evaluated were: ferric reducing antioxidant potential (FRAP), uric acid, glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT) and lipid hydroperoxides (LH). Analyses of variance for repeated measures revealed a significant effect of this treatment on FRAP and GPx. A moderate correlation was observed between FRAP and uric acid (r = 0.31). A significant interaction between type of treatment and time on lipid oxidation (HL) was also found. After ingestion of juice, relative average changes showed within the 2nd hour maximum elevation in the enzymatic activities of SOD (34.3%), CAT (18%) and GPx (8.5%), was reached. The juçara juice ingestion showed effect on the for the FRAP and enzymatic activity of GPx and interaction of lipid peroxidation that decreased over time. Further studies that investigate the antioxidant properties of the fruit juçara in the human are needed.
