Extra virgin olive oil can protect against the risk of dementia.
New research, conducted by Italian researchers at the School of Medicine, Temple University in the US, on mice suggests that adopting a diet rich in this ingredient can prevent the toxic accumulation of the protein tau, a hallmark of multiple types of dementia. Thanks to monounsaturated fatty acids, this condiment is known for its ability to reduce the risk of high cholesterol and heart disease.
The guinea pigs were fed for six months with an integrated diet with extra virgin from six months of age. At the end of the treatment, the animals fed the oil showed an improvement in memory and cognition in the learning tests. Additionally, by analyzing the brain tissue of mice prone to tauopathy, experts noted a 60% reduction in harmful tau deposits.
"Extra virgin olive oil has been part of the human diet for a long time and has many health benefits, for reasons that we do not yet fully understand", explains Domenico Praticò, among the researchers of the study. "The awareness that can protect against different forms of dementia offers us the opportunity to learn more about the mechanisms by which it acts to support brain health."
