Abstract The present study investigated the antioxidant activities and antihyperlipidemic effects of varying levels of inclusion of processed green leafy vegetables (Celosia argentea and Gongronema latifolium) on high fat diet-induced hyperlipidemic rats. The antioxidant assay revealed that the unblanched C. argentea had higher total phenolic content, total flavonoid content, DPPH·, ABTS·+, OH· and NO· radical scavenging activities than the blanched Celosia argentea. Conversely, the blanched G. latifolium had higher antioxidant activities than the unblanched G. latifolium. Seventy-five (75) male albino rats of average weight 180 ± 20 g were divided into fifteen (15) groups of five (5) animals each. The rats were fed for 4 weeks on diets specially formulated to contain 5%, 10% and 15% by weight of the leaves of the blanched and unblanched vegetables. lipid profile (TC: total cholesterol, TG: triglycerides, LDL: low density lipoproteins, VLDL: very low density lipoproteins and HDL: high density lipoproteins) and oxidative stress indicators were evaluated. The serum TC, TG, LDL and VLDL which significantly increased (p
