Effect of dietary virgin olive oil on serum lipids levels in rats

Background: Relationship between olive oil consumption and low cardiovascular mortality and mobility is the aim of current study. We were investigated of dietary virgin olive oil (VOO) effects on serum lipids profile. Methods: Experimental mature male rats were treated with VOO for 30 days at 0.25, 0.5 and 0.75 ml/kg/day and control group treated with saline at the same time via gastric gava...
