This study was designed to evaluate the nutritional property of plantain-based dough meal, antioxidant activity and dyslipidemia-ameliorating potential in high-fatinduced rats. The flour blends, that is, plantain 70%, soy cake 30% (PSC); plantain 65%, soy cake 30%, rice bran 5% (PSR); plantain 65%, soy cake 30%, oat-bran 5% (PSO); plantain 60%, soy cake 30%, rice bran 5%, oat-bran 5% (PSRO); and controls (100% plantain flour and Cerolina) were evaluated for proximate, amino acids, antioxidants, phenolic profile, and antihyperlipidemia. Protein, fiber, and energy composition varied from 2.2 to 4.97 g/100 g, 16.44 to 19.59 g/100 g, and 369.7 to 385.5 kcal/100 g, respectively. The essential amino acid index and predicted biological values of the foods ranged from 68.31% to 76.31% and 62.19% to 71.48%, respectively. Phenolic profiles (mg/g) were gallic acid (25.33-31.26), caffeic acid
