Brain and memory are strengthened by eating a special diet
The Mediterranean diet has consistently shown benefits for overall health.
Researchers at Tulane University School of Medicine in New Orleans recently discovered that diet is linked to improved memory through balanced bacteria in the gut.
In a study published in the journal Gut Microbe Reports, rats fed a Mediterranean style diet Over a 14-week period. This includes olive oil, fish, and fiber-rich foods.

Compared to those eating a Western diet high in saturated fat, rats consuming a Mediterranean diet had an increase in four types of beneficial gut bacteria and a decrease in five other types.

The rats were then instructed to maneuver through a series of mazes that tested their memory.
Those on a Mediterranean diet showed improved performance on maze problems.
“This study reinforces how the foods we choose can profoundly affect our gut microbiome and, in turn, our cognitive performance.”
The researchers concluded that the following individuals Mediterranean diet Following a “typical Western diet,” different gut bacteria patterns develop, and these gut changes are linked to learning and memory.

“Our results suggest that there may be a relationship between diet and modulated microbiota, peripheral immune function and cognitive function,” the study said.
“Further studies Diet-regulated gut microbiota is needed to determine the causal relationship between immune function and cognitive function and to explore additional brain mechanisms.

The Mediterranean diet group also demonstrated and maintained lower levels of improved cognitive flexibility and working memory. “bad” cholesterol.
Cory Mygrant, a registered dietitian dietitian in California at WellTheory, was not involved in the study but shared his reactions.

“As a dietitian, I’m excited to see more evidence highlighting the incredible power of the Mediterranean diet. heart health but also for brain health,” he told Fox News Digital.
“This study reinforces how the foods we choose can profoundly affect our gut microbiome and, in turn, our cognitive performance.”

Gut health is considered “the foundation of overall well-being” because it “affects everything from immunity,” Mygrant noted. mental health.”
“The Mediterranean diet is a fantastic choice to support this vital system,” he said. “Packed with vibrant, delicious foods, it can easily touch everyday life with simple tweaks.”
“Mediterranean diet lowers risk of cognitive decline and dementia by 50%.”
In an interview with Fox News Digital, study co-author Demetrius Maraganore, professor of neurology at Tulane University, highlighted the difference in cognitive function and gut microbial composition between Mediterranean and Western diets.
The Western diet’s reduced gut bacteria and overgrowth of bacterial species are similar to those observed here. Alzheimer patientshe told Fox News Digital.

The expert noted that following a Mediterranean diet can improve school and work performance.
“The Mediterranean diet reduces the risk of cognitive decline and dementia by 50% and contributes to higher global intelligence, memory function and executive function throughout life,” he said.

Tips for traveling to the Mediterranean
To start adopting a more Mediterranean-style diet, Mygrant suggested the following simple steps:
- Replace butter with olive oil
- Add an extra serving of vegetables to meals
- Experiment with plant-based proteins like lentils or peas
- Enjoy eating fish a few times a week
- Instead of ultra-processed foods, snack on nuts or fresh fruit

“It’s about celebrating real, whole foods while keeping things flexible and enjoyable,” he said.
Mygrant acknowledged that getting fresh produce and Mediterranean products can be difficult for some, but noted that the diet doesn’t have to be “all or nothing.”

“You can start with small, affordable exchanges like using canned fish, frozen vegetables and whole grains, and gradually increase the focus on more plant-based foods,” she says.
“The goal is to make nutritious options more accessible, no matter what your circumstances, while also prioritizing the connection between people. food and welfare.”

In future studies, the Tulane team aims to develop new treatments using nutrition and changes in the gut microbiome to prevent and treat Alzheimer’s disease, according to Maraganore.
