Title: Tackling Dementia: The MedWalk Study Unravels the Impact of a Combined Mediterranean Diet and Walking Routine
Get ready to walk your way to a healthier mind! Researchers are diving headfirst into an exciting study called the MedWalk intervention, aiming to shed light on the synergistic effects of following a Mediterranean diet and incorporating regular walks in your lifestyle, in relation to dementia and cognitive decline.
While both the Mediterranean diet and regular walking have shown promise in boosting brain health, this study takes it up a notch by investigating the combined effects. The study is being led by a team of researchers hailing from Australia, New Zealand, and the United Kingdom. Unfortunately, the project was hit hard by the COVID-19 pandemic, delaying its progress.
Despite the setbacks, the researchers have proudly shared their processes and ongoing analysis in the prestigious Journal of Alzheimer's Disease.
Initially designed to monitor cognition over a 2-year period, the trial has been adjusted to a single year due to the pandemic, with a broader participant base now recruited. The primary focus remains on observing a 12-month change in visual memory and learning among participants.
The MedWalk intervention isn't just about nourishing your body; it's a holistic approach that aims to boost cognition by addressing factors like mood, quality of life, health costs, cardiovascular health, arterial stiffness, and even biomarkers linked to cognitive decline.
To participate in this study, individuals aged 60 to 90 from South Australia and Victoria have been invited. This age group is particularly at risk for developing dementia. Recruitment initially focused on independent living retirement communities, but the pandemic necessitated expanding to the wider community as well.
Participants are randomly assigned to follow the MedWalk intervention or maintain their usual routine. The intervention itself blends dietary modifications with a supervised walking regimen, bolstered by psychosocial behavioral change techniques. Participants receive intensive support during the first 6 months and have additional assistance available for the following 6 months to help stay focused.
To help participants fully comprehend the Mediterranean diet, researchers provide explanations and offer essential items like extra-virgin olive oil for free. They also participate in group walking sessions for the initial six months, followed by monthly sessions for the remainder of the test year.
The Mediterranean Diet and Cognition
Certified nutritionist Conner Middelmann, who specializes in the Mediterranean diet and is not involved in the current study, spoke highly of the diet's potential benefits for brain health. Studies suggest that following the Mediterranean diet may reduce the incidence of dementia by offering various advantages like:
- Containing antioxidants that combat oxidative stress and inflammation, potentially significant contributors to cognitive decline and neurodegenerative diseases.
- Having plenty of omega-3 fatty acids, particularly docosahexaenoic acid (DHA), which is vital for brain health, and being linked to improved cognitive function and a lower risk of cognitive decline.
- Maintaining a balanced gut microbiome due to its high fiber content.
- Minimizing processed grains and sugars, thus lowering the risk of insulin resistance and inflammation.
- Discouraging consumption of ultra-processed foods, which have been tied to dementia.
Lastly, Middelmann highlighted that sharing meals with loved ones and daily exercise are also key aspects of the Mediterranean diet that may enhance brain health.
The Benefits of Walking for Cognition
Regular walking has been linked to slower cognitive decline as well. A study found that taking 10,000 steps a day could reduce the risk of dementia by half. Walking has been suggested to benefit brain health in ways such as:
- Enhancing blood flow to the brain, depending on walking intensity, duration, and frequency.
- Boosting levels of brain activity and reducing stress while improving feelings of well-being.
- Encouraging social interactions and exposure to nature, which can also be beneficial for the brain.
The current study is projected to complete its data-collection period by the end of 2023, with the final findings set to be published in the subsequent years. Stay tuned for updates on this fascinating study to see if the combined MedWalk intervention proves to be a valuable tool in the battle against cognitive decline and dementia!
