flag Extra-virgin olive oil linked to better brain health and gut diversity in adults over 55.

flag A study of 656 adults aged 55 to 75 found that consuming virgin olive oil, especially extra-virgin, was linked to better cognitive function and greater gut microbiota diversity compared to refined olive oil. flag Researchers suggest the higher levels of bioactive compounds in virgin olive oil may support a healthier gut microbiome, which could benefit brain health through the gut-brain axis. flag While the findings show associations rather than cause-and-effect, they highlight the importance of olive oil quality in dietary choices for long-term cognitive wellness. flag Further research is needed to confirm results across diverse populations.
