New research in mice suggests that adopting a diet rich in extra virgin olive oil can prevent the toxic accumulation of the protein tau, which is a hallmark of multiple types of dementia.
Due to its monounsaturated fatty acids, or „good“ fats, extra virgin olive oil is known for its ability to lower the risk of high cholesterol and heart disease.
Recently, however, several studies have suggested that extra virgin olive oil also has neuroprotective and cognitive benefits.
For instance, a 2012 study in mice found that the oil improves rodents‘ learning and performance in memory tests.
The presumed reason for these findings is that extra virgin olive oil is rich in polyphenols. These are powerful antioxidant compounds that may reverse disease- or aging-related learning and memory impairment.
A couple of years ago, a study that Medical News Today reported on found that extra virgin olive oil reduced early neurological signs of Alzheimer’s disease in mice.
