I was just back from supermarket, replenishing my stash for the Thanksgiving feast this week. Among all the things I bought, the most important thing despite turkey must be extra virgin olive oil.
With antioxidants and healthy fats, extra virgin olive oil (EVOO) is said to have many health benefits. Lately, it has gotten even more attention thanks to its potential for protecting memory and the brain.
EVOO can treat dementia in mice
According to previous studies, cognitive impairment is linked with the gradual buildup of tau in the brain, an abnormal form of a protein. Researchers now believe EVOO is a superfood, which can delay the decline in mental function.
The research team used mice with harmful tau deposits in the brain and then analyze the effect of EVOO on their brain tissue.
The mice were fed with EVOO when they were at an age equivalent to about 30 or 40 in human years. When they were at an age equivalent to 60 in humans, the researchers found a 60% reduction in the harmful tau deposits.
In addition, they found mice fed with EVOO finished memory and learning tests better than those who were not fed with EVOO.
In other words, the findings suggest that EVOO may have the potential to keep the brain young and protect people from dementia linked to the build-up of tau.
"EVOO has been a part of the human diet for a very long time and has many benefits for health, for reasons that we do not yet fully understand," said professor Domenico Praticò. "The realization that EVOO can protect the brain against different forms of dementia gives us an opportunity to learn more about the mechanisms through which it acts to support brain health."
So, if you are still using other kinds of oils, you can consider changing EVOO for more healthy benefits.
