Mental health preservation: Adopting a Mediterranean diet and leading an active lifestyle might offer protection
Let's dive into the nitty-gritty of an intriguing study that's all about keeping our minds sharp as we age! This groundbreaking research, dubbed the "MedWalk" experiment, is investigating the powerful combination of a Mediterranean diet and regular exercise – specifically, walking – to combat dementia and cognitive decline. Sounds cool, right?
The MedWalk intervention is short for a Mediterranean diet combined with walking, and researchers are hoping it could be a game changer for brain health. Previous research has indicated that both a Mediterranean diet and regular walking can paint a rosy picture for brain health, and now the MedWalk experiment is looking to confirm this benefit.
The study, headed by researchers from Australia, New Zealand, and the United Kingdom, began before the pandemic hit, but it was put on hold. Despite the hiccups, the researchers have kept the world in the loop by sharing their study processes and ongoing analysis, which they conveniently published in the Journal of Alzheimer's Disease.
Originally planned to run for two years, the pandemic forced the research team to modify their approach. They cut the follow-up period to a single year, and they even expanded the participant pool by recruiting seniors from both independent living retirement communities and The Great Wide Open.
So, what's the dealio with this MedWalk intervention? The researchers are especially curious about a 12-month change in visual memory and learning abilities for the participants. But they're also keeping an eye on other aspects like mood, quality of life, and health costs, as well as cardiovascular health and arterial stiffness.
The participants, who are aged 60-90 and hail from South Australia and Victoria, will be assigned to either the MedWalk intervention group or a control group that plays it cool and sticks to their normal diet and activity levels.
The MedWalk intervention is more than just a fancy name. It's a blend of dietarymodification and a supervised walking regimen, primed with psychosocial behavioral change techniques. The participants can expect plenty of support during the first six months, with additional assistance sticking around for the following six months to ensure they stay the course.
To help participants understand the concept, the researchers are offering tidbits of wisdom about the Mediterranean diet, like free extra-virgin olive oil and other goodies. After a baseline assessment of their aerobic fitness, the participants will join group walking sessions for the first six months. After that, they'll strap on their kicks for monthly sessions until the study wraps up at the end of 2023.
The Mediterranean diet is no stranger to brain health kudos. Certified nutritionist Conner Middelmann, who isn’t part of the current study, shed some light on why the Mediterranean diet is a shining star. Studies have indicated that a Mediterranean diet is associated with fewer cases of dementia and has been linked to lower rates of Alzheimer’s disease – the most common form of dementia. But before we get too carried away, Middelmann cautions that many factors, like genetics, lifestyle, and overall health, play a part in dementia risk. The bottom line: a healthy diet, like the Mediterranean diet, is just one piece of the brain health puzzle.
But how does walking fit into this picture of brain bliss? One study found that taking 10,000 steps a day can lower the risk of dementia by half! Other research has pointed to a connection between walking speed and dementia. A 2023 study found that aerobic exercise like walking can positively influence cognitive impairment. Brain health coach Ryan Glatt, not involved in this study, explained why walking might be neuroprotective. He suggests that walking could increase brain blood flow, enhance brain activity, and decrease feelings of overall stress while improving feelings of well-being. Not to mention, it might boost our social lives and offer exposure to nature – both of which have their own brain benefits.
The MedWalk study aims to provide valuable insights into lifestyle interventions that can slow cognitive decline and promote healthier aging. By combining dietary modifications with physical activity, the study offers a holistic approach to enhancing cognitive health and reducing dementia risk factors.
