Olive Oil Protects Liver

So do the onions.

Extra-virgin olive oil can protect the liver from oxidative stress. Researchers writing in BioMed Central's open access journal Nutrition and Metabolism exposed rats to a moderately toxic herbicide known to deplete antioxidants and cause oxidative stress, finding that those rats fed on a diet containing the olive oil were partially protected from the resulting liver damage.

Mohamed Hammami from the University of Monastir, Tunisia and King Saud University, Riyadh, Saudi Arabia, worked with a team of researchers to carry out the experiments in a group of 80 rats. He said, "Olive oil is an integral ingredient in the Mediterranean diet. There is growing evidence that it may have great health benefits including the reduction in coronary heart disease risk, the prevention of some cancers and the modification of immune and inflammatory responses. Here, we've shown that extra virgin olive oil and its extracts protect against oxidative damage of hepatic tissue".
