A two‑year analysis of 656 overweight adults aged 55‑75 in the PREDIMED‑Plus trial found that participants who regularly consumed virgin olive oil exhibited better preservation of cognitive function and greater gut‑microbiome diversity than those who used refined olive oil. The study linked the higher polyphenol content of virgin oil to these benefits, while refined oil correlated with reduced microbial diversity. Researchers stress the results are associative, not causal, and call for longer‑term trials. The findings add nuance to Mediterranean‑diet recommendations that often treat all olive oils as equivalent.
