Combined Effect of Mediterranean Diet and Walking on Dementia and Cognitive Decline Under Investigation
Maintaining Cognitive Wellness: Adopting Mediterranean Diet and Leading an Active Lifestyle Could Offer Protection
Scientists from Australia, New Zealand, and the United Kingdom are currently conducting a study to assess the combined impact of a Mediterranean diet and regular walking on cognition and the risk of dementia. The study, temporarily interrupted by the COVID-19 pandemic, is still ongoing, and its findings are set to be published by the end of 2023.
The "MedWalk" intervention, as it's called, combines dietary modification and a supervised walking regimen, complemented by psychosocial behavioral change techniques. The primary focus of the study is a 12-month change in visual memory and learning among participants aged 60 to 90.
This research follows a growing body of evidence suggesting that both the Mediterranean diet and regular physical activity, such as walking, may contribute to a reduced risk of dementia and slower cognitive decline. Previous studies have linked the Mediterranean diet to fewer cases of dementia, and research has also shown an association between walking and lower rates of Alzheimer's disease, the most common type of dementia.
By combining these two components, researchers aim to reinforce their impact on brain health and identify synergistic benefits. Participants, originally recruited from independent living retirement communities, will receive intensive support for the first six months, followed by additional assistance for the next six months to help them stay on track with their new lifestyle choices.
Special attention is being paid to biomarkers associated with cognitive decline, including glucose regulation, inflammation, nutrients, and oxidative stress.
Previous research has suggested that the Mediterranean diet may combat oxidative stress and inflammation, which are known contributors to cognitive decline and neurodegenerative diseases. The diet also contains omega-3 fatty acids, particularly DHA, which are crucial for brain health, and have been linked to improved cognitive function and a lower risk of cognitive decline. Moreover, the Mediterranean diet is rich in antioxidants and fiber, and low in processed grains and sugars, all of which can contribute to better overall health.
Regular walking, on the other hand, has been connected to improved brain health through enhanced blood flow, increased brain activity, reduced stress levels, and exposure to nature. It also has social elements that could contribute to positive cognitive impacts.
The data-collection period for this study will be completed by the end of 2023. The results are expected to provide valuable insights into the combined effect of the Mediterranean diet and walking on the risk of cognitive decline and dementia.
