the effect of kermanshahi animal oil on serum lipid profile in

background: during the procedure of kermanshahi oil production, some changes occur, which might affect the lipid profile of oil. the aim of this study was to investigate the effect of kermanshahi animal oil on the lipid profile in healthy men. methods: twenty five healthy men participated in this clinical trial study. after ten days, wash out period that subjects did not consume kermanshahi animal oil and it was replaced with same amount of butter, serum lipid levels (tc, tg, ldl-c and hdl-c), were measured. then subjects received 30 g/day kermanshahi animal oil for 1 month at lunch in replace of other fats. we asked to subjects do not use kermanshahi animal oil in other meals and replace it with the same amount of butter. after this period, serum lipid and lipoproteins were measured again. data were analyzed using paired t-test, independent t-test using spss soft ware version 12. results: following 30 days intake of kermanshahi animal oil, there was no change in the total cholesterol level (153.40±21.86 vs. 153.92±24.64 mg/dl). mean level of ldl-c increased (from 89.08±19.73 to 92.25±22.12 mg/dl) while tg concentration decreased from 112.84±22.33 to 107.76±25.46 and hdl-c level decreased from 41.40±5.08 to 40.76±6.39 mg/dl, but none of these differences were significant (p>0.05). conclusion: present study showed that consumption of 30 g/day kermanshahi animal oil for 1 month has no effect on serum lipid levels in healthy men.
