Abstract
This study was carried out to investigate the effect of trans fatty acids on haematological indices. This was done by supplementing the diets fed to the albino Wistar rats with different concentrations of thermally oxidized palm oil and margarine as sources of trans fatty acids. Fifty albino Wistar rats were used for this study and were randomly selected into five groups of ten rats. Group 1 rats serving as the control received only the stock diet. Group 2 received 85% rat pellet supplemented with 15% margarine. Group 3 was fed with 75% rat pellet and 25% margarine. The fourth group was fed with 85% rat pellet supplemented with 15% thermally oxidized palm oil. Group 4 was fed with 75% rat pellet supplemented with 25% thermally oxidized palm oil. The feeding experiment lasted for six weeks at the end of which rats were sacrificed for determination of haematological indices. Results showed significant (p<0.05) decrease in Red Blood Cell (RBC) count, White Blood Cell (WBC) and platelet counts, Haemoglobin (Hb) concentration and Packed Cell Volume (PCV) in all test groups. This probably suggests that trans fatty acids may adversely affect the health of an individual and should be reduced in diet.
