Mental wellness: Adopting the Mediterranean diet and an active lifestyle could offer protective benefits
Researchers Investigate Combinatory Impact of Mediterranean Diet and Walking on Dementia and Cognitive Decline
Scientists from Australia, New Zealand, and the United Kingdom are investigating the effect of a lifestyle intervention called "MedWalk" on reducing the risk of cognitive decline and dementias such as Alzheimer's. This research, set to conclude in late 2023, combines a Mediterranean diet with a regular walking regimen to assess their potential synergistic benefits for brain health.
The ongoing study, initially designed to span over two years, was altered due to the COVID-19 pandemic, with the research period reduced to one year. Despite the schedule adjustment, the authors believe the study's modified format will yield robust findings. The primary focus is on observing the impact of the intervention on visual memory and learning over 12 months.
The MedWalk intervention consists of dietary modifications and a walking program reinforced with psychosocial behavioral techniques. Participants engaging in the MedWalk intervention, aged between 60 and 90, hail from independent living retirement communities in South Australia and Victoria. In response to the pandemic, efforts have also been made to recruit participants from the wider community.
Special attention is given to biomarkers linked to cognitive decline, including glucose regulation, inflammation, nutrients, and oxidative stress. Participants are randomly divided into the MedWalk intervention group and a control group maintaining their usual diet and activity level.
Previous research has underscored the connection between the Mediterranean diet, walking, and cognitive health. Nutritionist Conner Middelmann, whose specialty is the Mediterranean diet, observed that numerous studies suggest a reduced risk of dementia for those following such a diet. Similarly, regular walking is associated with delayed cognitive decline, as studies have shown a 50% risk reduction for dementia among those taking 10,000 steps per day.
The benefits of the Mediterranean diet for brain health may stem from its rich antioxidants, Omega-3 fatty acids, high fiber content, and fewer processed grains and sugars. In addition, the dietary changes support social interactions and regular exercise, both of which have also been linked to brain health. Brain health coach Ryan Glatt highlighted that walking may boost brain blood flow, cognition, and overall well-being, while providing social benefits and exposure to nature.
The current study's data collection will be completed by the end of 2023. Upon its conclusion, results are expected to shed light on the potential benefits of combining the Mediterranean diet and walking and provide valuable insights to improve cognitive health in older adults.
