The Mediterranean diet has continuously shown benefits for overall health.
Researchers at the Tulane University School of Medicine in New Orleans recently discovered that the diet is linked to improved memory through balanced bacteria in the gut.
In the study, which was published in the journal Gut Microbe Reports, rats were fed a Mediterranean-style diet over a 14-week period. This included foods rich in olive oil, fish and fiber.

Compared to those who ate a Western diet high in saturated fat, the rats that consumed the Mediterranean diet showed increases in four types of beneficial gut bacteria and decreases in five other types. Researchers at the Tulane University School of Medicine recently discovered that the Mediterranean diet is linked to improved memory through balanced bacteria in the gut.

Those that were on the Mediterranean diet exhibited improved performance in the maze challenges. "This study reinforces how the foods we choose can profoundly impact our gut microbiome and, in turn, our cognitive performance." The researchers deduced that individuals who follow the Mediterranean diet develop different gut bacteria patterns compared to those following a "typical Western diet," and that those gut changes were associated with learning and memory.

"Our results suggest that there may be a relationship between diet-modulated microbiota, peripheral immune function and cognitive function," the research concluded.
" Additional studies are needed to determine the causality between diet-modulated gut microbiota, immune function and cognitive function, and to explore additional brain mechanisms." Gut microbiome developed by certain dietary choices can improve cognitive function, the study suggested.
