Abstract
and Objectives: Nutritional role of edible oils, which may induce diverse effects on nervous system, is one of the issues considerations in modern communities as well as our country. Tissue changes and thereby behavioral alteration are among these effects. In present study the effect of nutritional oils on serum lipid profile and memory was studied.
Methods and Methods: Twenty Wistar rats in 2 equal nutritional groups were studied: 1) Control group 2) Ghee oil group. After 5 weeks of taking their particular diets, rats tested by shuttle box system for passive avoidance learning. Then blood samples were obtained and lipid profile was determined using an autoanalaizer and Randox kits. Finally using SPSS software, T-Student and pearson method results were analyzed (p < 0.05 was considered as significant).
Results: In ghee oil group based on HDL and LDL (which suggests propensity in arteriosclerosis) indicators as compared with control group was found to be useful for prevention of cardiovascular diseases. This oil induced positive effects on memory retrieval after 24 and 72 hours (P< 0.05).
Conclusion: Based on the positive effects of ghee oil on memory and prevention of cardiovascular disease, we suggest including ghee oil (even in small amounts) in the diet. The advisable amount added to family diet requires further investigations.
