The effects of the dietary addition of 2.5 % (w/w) Amaranthus mantegazzianus protein isolate (AI) on blood pressure, lipid profiles and antioxidative status of Wistar rats were evaluated. Six diets were used to feed animals during 28 days: (base (AIN93G), Chol (cholesterol 1 %, w/w), CE (α-tocopherol 0.005 %, w/w), CholE (cholesterol 1 % (w/w) + α-tocopherol 0.005 %, w/w), CAI (AI 2.5 % w/w), CholAI (cholesterol 1 % (w/w) + AI 2.5 %, w/w). Lipid profiles of plasma and liver and faecal cholesterol content were analyzed. Antioxidant status was evaluated by the ferric reducing activity of plasma (FRAP), the 2-thiobarbituric acid (TBA) assay and superoxide dismutase (SOD) activity in plasma and liver. Blood pressure was measured in the tail artery of rats. CholA group presented a significant (α
