“green Mediterranean Diet” Linked to Slower Brain Aging,New Research Suggests
October 5,2025 - A dietary approach emphasizing plant-based foods and healthy fats,known as the “Green Mediterranean diet,” appears to considerably slow cognitive decline and preserve brain health as people age,according to research presented this week. The findings, which build on previous studies demonstrating the benefits of the traditional Mediterranean diet, suggest a focused emphasis on green plant foods may offer even greater neuroprotective effects. This has major implications for the projected rise in age-related dementia cases globally, possibly offering a modifiable lifestyle factor to mitigate risk.
The Green Mediterranean diet,differing from its traditional counterpart,prioritizes higher consumption of vegetables – especially leafy greens – alongside limited meat intake and a focus on plant-based proteins. Researchers believe the abundance of polyphenols and other beneficial compounds in these foods contribute to reduced inflammation and oxidative stress, key drivers of age-related cognitive decline. With the global population aging rapidly, and dementia rates projected to soar, identifying accessible and effective preventative strategies is a critical public health priority.
The study, conducted by researchers at Ben-Gurion University of the negev in Israel, involved over 300 adults aged 65-75. Participants were randomly assigned to one of three dietary groups for 18 months: a traditional Mediterranean diet, a Green Mediterranean diet, and a control group instructed to follow their usual dietary habits.Cognitive function was assessed at the beginning and end of the study using a comprehensive battery of tests.
Results indicated that participants following the Green Mediterranean diet exhibited the most significant improvements in cognitive function, including memory, attention, and processing speed.Specifically, the Green Mediterranean diet group showed a 14% enhancement in a global cognitive score compared to the control group. The traditional Mediterranean diet group also showed improvements, but to a lesser extent.
“We observed that the Green Mediterranean diet had a more pronounced effect on slowing age-related cognitive decline than the traditional Mediterranean diet,” explained Dr. Gal Tsaban, lead researcher on the study.”This suggests that increasing the intake of green plant foods, while reducing meat consumption, can have a substantial impact on brain health.”
The researchers hypothesize that the increased intake of polyphenols, found abundantly in vegetables like spinach, kale, and broccoli, plays a crucial role in protecting brain cells from damage. Polyphenols are known for their antioxidant and anti-inflammatory properties, which can definitely help combat the processes that contribute to neurodegenerative diseases.
while further research is needed to confirm these findings and determine the optimal dietary composition, the study provides compelling evidence that the Green Mediterranean diet could be a powerful tool for preserving cognitive function and promoting healthy brain aging. Experts recommend incorporating more leafy greens, vegetables, and plant-based proteins into your diet, alongside healthy fats like olive oil, to reap the potential benefits.
