Abstract Effect of chronic consumption of thermoxidized palm oil diets on blood parameters in albino rats fed with garlic was investigated. Twenty one albino rats were selected and assigned to three groups of seven each. Group 1 (control group) were fed normal rat chow. Group 2 were given thermoxidized palm oil diet Group 3 were given thermoxidized palm oil diet and garlic. Result showed no significant different in blood parameters among the groups (10.67±1.93, 8.25±1.8 and 12.43±2.96 for thermoxidized palm oil, thermoxidized palm oil + garlic and control groups respectively. The Red blood cell showed no significant difference among the groups (8.14±0.22, 8.18±0.18 and 7.17±0.29) for thermoxidized palm oil, thermoxidized palm oil + garlic and the control group. There was no significant difference among the groups in Hb concentration of 45.90±0.78, 56.55±1.32 and 43.92±1.16 for thermoxidized palm oil, thermoxidized palm oil + garlic and control group. Mean corpuscular haemoglobin concentrations were 16.97±0.38, 16.84±0.20 and 17.38±0.47 for thermoxidized palm oil, thermoxidized palm oil + garlic and control groups and showed no significant difference. There was also no significant difference in the mean corpuscular haemoglobin concentration among the groups with 30.02±0.18, 30.28±0.35 and 30.38±0.35 for thermoxidized palm oil, thermoxidized palm oil + garlic and control group. Finally the platelet count also showed no significant difference among the groups with 782.50±39.15, 907.00±12.34 and 821.83±160.23 for thermoxidized palm oil, thermoxidized palm oil + garlic and control group. From the results, it may be deduced that chronic consumption of thermoxidized palm oil diets in rats fed with garlic has no adverse effect on its blood parameters.
