Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder caused by excess consumption of hypercaloric foods. Guavira (Campomanesia sp.) pulp has broad technological applicability, yet the peel and seeds are considered industrial residue. The objective of this unprecedented study was to evaluate the effects of the flour from guavira's industrial residue (GF) consumption in rats fed with hypercaloric diet (HD). During 65 days, 50 rats were separated into a control group: 1%, 2%, 4% and 8% HD with GF complementation in the diet. The GF chemical composition, phenolic compounds, antioxidant capacity, serum biochemical parameters (glucose, cholesterol, HDL, non-HDL, triglycerides, AST, ALT, and oral glucose tolerance test), fat liver content, and hepatic histomorphology had been characterized. GF is mainly composed of fibres, with phenolic content of 7,391.09 mg AGE/100 g GF and relevant antioxidant capacity (IC50 2.22 and ORAC 155.68 μmol/TE g-1 ). Serum biochemical analysis did not differ statistically (except ALT reduction, p < .05). Fat liver content was smaller on HD2%GF (p < .0001). The control group and 1% GF showed greater diffuse microvesicular steatosis compared to the other groups when using hepatic morphological analysis (p < .05). GF consumption attenuated NAFLD caused by a hypercaloric diet, and this effect may be related to the fibre content and bioactive compounds in GF.
