Superfruits have a high nutritional value due to their richness in nutrients, antioxidants, proven or potential health benefits and taste appeal. However, there are no scientific criteria for defining which fruits are superfruits. In Brazil, several palms have an edible palm heart, the best known and most widely appreciated of which is called Acai (Euterpe oleracea). Euterpe edulis Mart., commonly called jussara, is an evergreen species that grows in the rainforest. Having initially been consumed in the form of juice and pulp, they have since been incorporated as an ingredient in many foods. A risk assessment to identify adverse health effects is a prerequisite for taking forward the development of new drugs, cosmetics and foods. To make a toxicological evaluation of E. edulis, in the present work this prerequisite was met by an interdisciplinary network that performed mass spectroscopy analyses, blood biochemistry, genotoxicity, bacterial reverse mutation and cytotoxicity assays. Positive mutagenicity results were detected for Salmonella typhimurium TA97 at low doses, and positive results were also obtained for the mammalian erythrocyte micronucleus assay, indicating that the pulp of E. edulis contains compounds with the capacity to induce mutagenicity and clastogenic/aneugenic effects.
