Green-Mediterranean Diet Linked to Slowing Brain Aging
A green-Mediterranean diet including green tea and Mankai may help slow down brain aging, potentially preserving cognitive health over time. Learn about this groundbreaking study and its implications for healthy aging.
Recent research suggests that following a green-Mediterranean diet, which incorporates green tea and the aquatic plant Mankai, may help delay the natural aging of the brain. The study, published in the journal Clinical Nutrition, examined the effects of different dietary patterns on brain health over an 18-month period, involving around 300 participants from the ongoing DIRECT PLUS trial.
Participants were assigned to one of three diets: a standard healthy diet, a traditional calorie-restricted Mediterranean diet rich in vegetables, poultry, and fish, or the green-Mediterranean diet that added green tea and Mankai. Findings revealed that those adhering to the green-Mediterranean diet exhibited decreased levels of certain blood proteins associated with accelerated brain aging, indicating a protective effect against cognitive decline.
The study underscores the potential benefits of anti-inflammatory foods like green tea and Mankai in maintaining brain health. Dr. Anat Meir from Harvard T.H. Chan School of Public Health noted that analyzing circulating proteins provides a real-life insight into how lifestyle and diet influence brain aging processes long before symptoms appear. Senior researcher Iris Shai emphasized that such dietary interventions could be key in preserving cognitive function as people age.
This research adds to the growing evidence supporting plant-based, anti-inflammatory diets for healthy aging and cognitive preservation.
