title: Extruded whole grain diets based on brown, soaked and germinated rice. Effects on the lipid profile and antioxidant status of growing Wistar rats. Part II.
abstract: The influence of whole grain (WG) rice based diets on the lipid profile and antioxidant status was evaluated. Thirty-two male Wistar rats were fed with Control (C), extruded Brown rice (B), extruded Soaked whole rice (S) and extruded Germinated whole rice (G) diets for 60 days. Triacylglycerols (TAGs), cholesterol and malondialdehyde equivalent (MDA eq.) in serum and liver were determined. Catalase (CAT), Glutathione Reductase (GR) and Glutathione Peroxidase (GPx) enzyme activities and Glutathione Reduced (GSH) and Oxidized (GSSG) in the liver were analyzed. Animals consuming B and S diets presented lower body weight gain. All WG diets reduced TAGs in serum and MDA eq. content in liver in comparison with the C diet. WG rice diets improved the redox status in animals mainly fed G due to their higher GR activity and GSH/GSSG ratio.
