Effect of Cocoyam Modified Starch (Xanthosoma sagittifolium), Beetroot Juice, Cocoyam Modified Starch Adsorbing Beetroot on Plasma Selenium and Glutathione Peroxidase of Pre-Diabetic Rat

Abstract

This research was aimed to identify effect of cocoyam (Xanthosoma sagittifilum) and beetroot on plasma Glutathione Peroxidase (GPx) and selenium of pre-diabetic rats. The pre-diabetic rats were fed with cocoyam modified starch, beetroot juice and cocoyam modified starch adsorbing beetroot for 3 weeks. The plasma selenium and GPx were analyzed. The blood were withdrawn once in a week during 3 weeks. Selenium levels in pre-diabetic rats consumed each of feeding treatment were not significantly diffrent as compared to control feeding (AIN). Plasma GPx activity in pre-diabetic rats consumed cocoyam modified starch and cocoyam modified starch adsobing beetroot tended to have higher values than control in every week. Plasma GPx activity of pre-diabetic rats consumed beetroot juice tended to have higher values than control at the first and the second week.
