Regular consumption of olive oil protects the brain - and reduces the risk of dementia mortality. Scientists from Harvard University analyzed the connection between diet and dementia-related deaths using nutritional questionnaires and death certificates.
Olive oil promotes a healthy brain - regardless of other diet. People who replace a teaspoon of mayonnaise or margarine with olive oil every day still have an eight to 14 percent lower risk of dying from dementia. It is also possible that olive oil has an indirect influence on brain health by promoting cardiovascular health.
