Mango consumption has shown bioactive properties against several diseases like diabetes, therefore, we evaluated how a mango-supplemented diet affects metabolic pathways in diabetic rats. Serum and liver samples were collected from 26 rats divided into 3 groups (healthy, untreated diabetic and mango-treated diabetic) after dietary intervention and analysed using an LC-MS untargeted metabolomic strategy. Twenty-six and 29 metabolites in serum and liver were potentially annotated, showing significant differences among groups. Several affected pathways were due to the disease state [fatty acids (i.e. palmitoleic, linolenic, stearidonic, eicosapentaenoic, docosahexaenoic acids and others), bile acids (i.e. glycocholic acid) and amino acids (i.e. leucine, isoleucine and valine)], and others due to mango supplementation (increased hepatic bioaccumulation of euxanthone, a mangiferin metabolite, and increased glutathione concentration). These results suggest that a mango-supplemented diet exerted a significant antioxidant effect in the liver of diabetic rats, likely due to its phenolic compounds, like mangiferin and its metabolites.
