Spanish study finds virgin olive oil improves gut bacteria and cognitive function in older adults

Virgin olive oil consumption may improve cognitive function in older adults by positively impacting gut bacteria. A Spanish study of 656 overweight or obese adults aged 55-75 found that those consuming virgin olive oil showed better cognitive performance and greater gut microbiome diversity over two years. The research suggests that the quality of dietary fats, like those in virgin olive oil, is crucial for preserving brain health during aging, potentially mitigating cognitive decline.
