Olive oil protects liver from oxidative stress, rat study finds

Olive oil protects liver from oxidative stress, rat study finds: "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."
