The genus Euterpe originates a specie of palm popularly known as juçara palm (Euterpe edulis). The juçara palm grows in the Atlantic Forest in Brazil. The fruits of juçara have sensorial and nutritional properties similar to açaí (Euterpe oleracea). Juçara and açaí are fruits rich in phenolic compounds, especially anthocyanins. Studies have shown that intake of fruits and vegetables rich in phenolic compounds attenuate oxidative stress state and may reduce the risk of developing chronic diseases. This study evaluates the effect of acute intake of juçara and açaí juices on oxidative stress biomarkers in eleven healthy volunteers in a cross‐over trial. Blood samples were collected before and after 1 and 2 hours of juçara juice, açaí or control drink (water). The biomarkers of oxidative stress analyzed were: glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAC) and total oxidant status (TOS). The juçara and açaí juices decreased TOS significantly after 1h and 2h of ingestion. The CAT activity increased after 1h of juçara juice ingestion and after 2h after açaí consumption. Açaí juice was able to increase GPx activity significantly after 2h of ingestion, in relation to the baseline values. These results demonstrate a positive effect of juçara and acai juice intake on the antioxidant capacity and attenuation of oxidative damages in healthy individuals.
