ABSTRACT

Aim: The aim of the present study is to access the effect of olive oil supplementation against high fat diet induced fatty liver disease in mice. Methods: Mice were divided into five groups: Group I (normal diet), Group II (high fat diet), Group III (olive oil), Group IV and V (High Fat Diet along with olive oil). All mice were fed for 16 weeks with weight measurements every 2 weeks and then sacrificed. Biochemical analysis of blood samples was done and mice livers were histologically examined. Results: Group II mice showed significant increase in body weight as compared with Group I (p < 0.05). Group IV and V mice were significantly (p < 0.05) reduced in body weight as compared with Group II. Olive oil groups had significantly decreased triglyceride and low density lipoprotein levels as compared with Group II whereas high density lipoprotein levels were significantly increased (p < 0.05). The liver enzymes were significantly increased in Group II as compared with other groups (p < 0.05). Liver histopathology revealed drastically increased lipid droplets in Group II mice as compared with Group IV & V. Conclusion: Olive oil causes weight reduction, decreases the serum triglycerides, normalizes the liver enzymes and significantly reduces the accumulation of fat in liver. Therefore, olive oil may represent a potential therapeutic alternative for NAFLD and other fatty diseases.
