Is Your Diet the Key to Slowing Down Brain Aging?

New research reveals that embracing the green-Mediterranean diet—packed with green tea and the unique aquatic plant Mankai—could hold the secret to slowing brain aging. This exciting finding was highlighted in a recent study published on August 23 in the journal Clinical Nutrition.

A Collaborative Effort to Understand Brain Health

Led by experts from esteemed institutions like Ben-Gurion University, Harvard T.H. Chan School of Public Health, and the University of Leipzig, the study explores the connections between diet and cognitive health. It specifically examines how diet can influence brain age, especially concerning conditions like mild cognitive impairment and Alzheimer’s disease.

How the Study Was Conducted

In the DIRECT PLUS trial, one of the most extensive studies examining the brain-diet relationship, researchers analyzed data from nearly 300 participants. Over 18 months, participants followed one of three diets: a standard healthy diet, a calorie-restricted Mediterranean diet, and the revolutionary green-Mediterranean diet. This last option not only includes the traditional Mediterranean ingredients but also features green tea and Mankai.

The Surprising Results

By measuring protein levels in the blood, researchers identified a link between higher levels of certain proteins and accelerated brain aging. Remarkably, participants on the green-Mediterranean diet showed lower levels of these proteins. The scientists believe that the anti-inflammatory properties of green tea and Mankai may play a critical role in this protective effect.

A New Window into Brain Health

Anat Meir, a postdoctoral research fellow at Harvard Chan School and co-lead of the study, emphasized the importance of observing circulating proteins to understand real-life influences on brain aging. She stated, "This approach offers a unique glimpse into brain health, revealing biological changes long before any potential symptoms arise. By mapping these protein signatures, we can gain valuable insights into how dietary interventions could help maintain cognitive function into old age."

Prominent Figures Behind the Study

The study’s senior author, Iris Shai, is an adjunct professor of nutrition at Harvard Chan School, highlighting the institution’s dedication to advancing our understanding of health and nutrition. Alongside her, co-authors include notable researchers Dong Wang, Frank Hu, and Meir Stampfer.
