Enhancing Brain Health: The Mediterranean Diet and Regular Exercise as Potential shields
A groundbreaking study, dubbed the "MedWalk intervention," explores the potential synergy between a healthy Mediterranean diet and regular walking, to combat dementia and cognitive decline. Let's dig a little deeper into this fascinating combination.
Brain health experts have long recognized the benefits of both a Mediterranean diet and regular exercise like walking. This cutting-edge study aims to build on that evidence by demonstrating the advantages of adopting both aspects simultaneously.
The study, conducted by researchers from Australia, New Zealand, and the United Kingdom, investigates if following a "MedWalk" lifestyle can help reduce the risk of cognitive decline - including memory losses related to Alzheimer's disease - over a one-year period.
Cognitive improvements under the researchers' spotlight are significant, particularly in the areas of visual memory and learning. Additionally, they're keen on exploring the intervention's effects on a range of factors such as mood, quality of life, health expenses, cardiovascular health, and arterial stiffness.
Participants, all aged between 60 to 90, hail from South Australia and Victoria, with many recruited from retirement communities. To accommodate COVID-19-related challenges, the follow-up period has been shortened to one year, and the research team expanded their participant pool by reaching out to the wider community.
A primary focus for the team is on biomarkers linked to cognitive decline, including glucose regulation, inflammation, nutrients, and oxidative stress. Participants are divided into two groups: an experimental group undergoing the MedWalk intervention and a control group maintaining their usual lifestyle.
The MedWalk intervention involves adhering to a Mediterranean diet enhanced with extra-virgin olive oil and selecting nutrient-rich foods, as well as a guided walking program. Participants receive intensive support for the initial six months, followed by ongoing assistance.
The implications of a Mediterranean diet and regular physical activity for cognitive health are multi-faceted:
-Rich in antioxidants, the diet may combat inflammation and oxidative stress, both crucial factors in cognitive decline and neurodegenerative diseases.-DHA, an essential omega-3 fatty acid, helps build and sustain brain health, and is abundant in the Mediterranean diet.-The Mediterranean diet's fiber content supports a balanced gut microbiome, thus reducing the risk of inflammation and insulin resistance.-Processed foods - common culprits in dementia - are discouraged in this diet.-Staying active, as done through walking, enhances brain blood flow and can contribute to improved cognitive function and lower cognitive decline risk.
Regular exercise, be it walking or otherwise, has also been shown to reduce dementia risk, with one study suggesting a 50% lower risk associated with taking 10,000 steps per day. Other studies point out that walking may improve brain health by bolstering blood flow, supporting neuroplasticity, and minimizing feelings of stress and anxiety.
As the study's data-collection period draws to a close by the end of 2023, we eagerly await the findings. This could prove to be a pivotal milestone in our understanding of combating cognitive decline and dementia through lifestyle factors like diet and exercise. Stay tuned!
