Abstract:
Adult male and female Wistar rats were fed isoenergetically for a 6 week period with a lipogenic diet containing a 20% fat mixture which caused fat‐metabolism disturbance. One group consumed the mixture of sunflower oil and lard in a ratio of 0.91 P/S, the other group the interesterified form of the same mixture. The linoleic acid content of the mixtures was 0.4%. The fat mixture of the third group's diet was adjusted with soya oil to a linoleic‐acid content of 0.8%. The results were compared to the control data obtained in rats fed with a normal diet. The changes in various lipid indices of the serum and the liver and the levels of some metals in the liver were analysed. It was found that. — in comparison to the control on the effect of the lipogenic diet the total lipid and cholesterol contents of the serum increased significantly in all groups (a significantly higher value being observed for the females than for the males) whereas the HDL‐C content decreased. As to the effect of the fat mixtures there were no considerable difference. — in the liver of the females a similar trend of high lipid values was observed with the consumption of the different fat mixtures; in the liver of males the interesterified fat mixture and the fat mixture with a higher linoleic acid content caused a significantly higher total lipid, triglyceride, and total cholesterol accumulation than the non‐interesterified mixture. — the iron content of the liver decreased in the males of all three groups, but more significantly with interesterification and increasing the linoleic‐acid content of the diet, while in the females the zinc content of the liver decreased. — our experimental model of the fat‐metabolism disturbance seems to be suitable for the determination of the effects of slight dietary changes i.e. for the study of changes in food technology.
