Extra-virgin olive oil linked to better brain health and gut diversity in adults over 55.
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.
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.
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.
Further research is needed to confirm results across diverse populations.
