ABSTRACT
Brazil nut (Bertholletia excelsa H.B.K.) is characterized by its high nutritional and energetic value. It contains high levels of l-arginine, antioxidant vitamins, phenolic compounds, and phytosterols. In addition to their biological functions, bioactive compounds and essential fatty acids present therapeutic effects on chronic disease prevention through their antioxidant effects. Thus, this review aims to present the most recent scientific evidence on the effect of Brazil nut on human health. A search for scientific articles was carried out through the MEDLINE/PubMed, Science Direct, and LILACS databases, considering articles published between the years 2010 and 2023. The results showed that Brazil nuts and Brazil nut oil, when consumed regularly and associated with a balanced diet, can improve lipid profile, attenuate inflammatory response, and improve oxidative stress through increased activity and gene expression of antioxidant enzymes. However, further studies are recommended to better understand the mechanisms of action.
