Green Mediterranean Diet May Aid Brain Health
Health Points
- Following a green Mediterranean diet could slow cognitive aging, according to new research.
- Eating more plant-based foods and fewer animal products may help protect the brain and reduce harmful proteins linked to aging.
- Adding foods rich in polyphenols—like green tea, walnuts, and leafy greens—may play a key role in maintaining brain health over time.
Experts highlight that brain age is influenced by genetics, lifestyle, and dietary choices, giving people control over certain aging aspects.
By tracking changes in specific blood proteins over 18 months, researchers saw how shifting to a green Mediterranean diet may help reduce age-related changes in the brain.
“This approach offers a dynamic view of brain health, allowing us to detect biological changes long before symptoms appear. By mapping these protein signatures, we gain valuable insights into how interventions like diet may help maintain cognitive function as we age.”
The green Mediterranean diet swaps most animal products for more plants and plant-based foods, focusing on nutrients with strong anti-inflammatory and antioxidant properties.
Martha Theran, RDN, explains that this way of eating can be a powerful tool to preserve heart and brain health as we get older.
In a long-term study, participants who followed the green Mediterranean diet saw a decrease in two proteins—galectin-9 and decorin—linked to faster brain aging.
“This indicates a potential positive effect on biological processes related to brain aging through blood protein modulation,” says Dafna Pachter, lead researcher.
Brain aging involves neuron loss and shrinking brain volume, which can affect memory and thinking skills, but the study shows that diet changes may slow these effects.
Past research supports these findings, showing both traditional and green Mediterranean diets can reduce brain shrinkage and offer neuroprotection.
According to Theran, the green Mediterranean diet goes a step further than the traditional version by increasing foods rich in polyphenols, like green tea and walnuts, for extra brain protection.
While more studies are needed, especially in women, experts note that MRI measurements are robust indicators of brain health, even if not direct clinical diagnoses.
Theran recommends making small shifts like adding green tea, more leafy greens, and cutting back on red meats to support brain well-being.
