Scientists Say This Type of Olive Oil Could Boost Brain Power

A two-year research study reveals that extra virgin olive oil may protect brain health by promoting a diverse gut microbiome. Participants who consumed extra virgin olive oil demonstrated better cognitive performance and harbored more beneficial gut bacteria compared to those using refined olive oil. Scientists identified specific microbes responsible for these brain-boosting effects, establishing a direct link between gut health and cognitive function. This finding suggests that selecting high-quality extra virgin olive oil could be a simple, accessible dietary strategy to support brain health and potentially reduce cognitive decline as you age.
