The nutritional properties of jucara fruit are similar to those of acai fruit, rich in bioactive compounds with antioxidant potential. This cross-over study evaluated the effects of the acute consumption of jucara juice in eleven healthy volunteers. Blood samples were collected before and 1, 2, and 4 h after juice or water (control) intake to measure the ferric reducing antioxidant potential (FRAP), uric acid, reduced glutathione (GSH), glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), and lipid hydroperoxides (LH). Repeated measures analysis of variance verified that the treatment increased the FRAP (p = 0.02) and the enzymatic activity of GPx (p = 0.02). In addition, there was a significant treatment time interaction, and a decrease in LH (p = 0.02) was observed over time after the ingestion of jucara juice. Based on these results, further studies should be carried out to evaluate the clinical effects of jucara juice consumption, particularly regarding its antioxidant potential in humans.
