Navigating the pathway from burgers to impasse: Understanding how fast food disrupts our internal navigational system.
Navigating the Maze of Fast Food: How Our Diet Affects Our Spatial Abilities

It seems that our fondness for fast food can influence more than just our waistlines – it might also impact our brain's capacity to navigate space and remember routes. Opt for that hike or tour after a burger at your own risk, as you may find yourself lost. A team of researchers from Sydney University discovered that a diet rich in fats and sugars hampers spatial memory, a crucial brain function that aids us in recalling routes, calculating distances, and navigating new places. The findings, published in the International Journal of Obesity, shed light on the hidden dangers of hot dogs and fries.
Fast Food and Memory Lapses
55 twenty-something frequent fast food fans were asked to navigate a labyrinth to discover a hidden treasure chest. They had six attempts, with four minutes allotted for each try. If they erred, they were shown the correct path for ten seconds. In the ultimate test, the chest was removed, and they needed to mark its location on a map from memory.
The researchers discovered that participants who consumed fast food, such as burgers, hot dogs, and processed goods, more than twice a week, and those who sweetened their beverages or washed down mass-produced meals with soda, underperformed in remembering the route and made more mistakes [1][2].
Dr. Dominic Tran, study lead from the Faculty of Psychology at Sydney University, explains that this disruption impacts the function of the hippocampus, a key brain region essential for spatial orientation and memory.
Furthermore, the connection between dietary habits and memory and navigation difficulties persisted even when accounting for body mass index (BMI) and overall memory ability. This suggests that it's not just about obesity; it's the food's composition that's detrimental to the brain [3][5].
The good news is that these changes can be reversed by adopting a healthier diet, according to Dr. Tran.
Recent data reveals that an inappropriate diet specifically harms the hippocampus [2]. This is a concerning finding, as cognitive abilities in young adults are typically considered stable compared to those of older adults [6].
So, What's the Way Forward?
Researchers suggest decreasing the consumption of products with high saturated fats (such as fried food and baked goods) and refined sugars (like soda and candy) [1][2]. Instead, opt for vegetables, fruits, whole grains, and nutritious fats (such as nuts and fish) [1][2].
Going green today is not just an investment in your looks; it's also an investment in your brain's future, says Dr. Tran [2].
It's also helpful to take short breaks for physical activity, especially while immersed in intellectual work or study, as working sedentary hours. Engaging in muscle contractions releases special hormone-like compounds called myokines, which are highly beneficial for the body, improving fat tissue, blood vessels, and significantly affecting the brain. Muscles literally stimulate our hippocampus, enhancing this memory and learning center [7].
sidenote: Myokines are proteins released by muscles during activity, providing various benefits such as improved brain function, mood regulation, and metabolic health.
Staying active and choosing a nutritious diet is essential for maintaining cognitive health and navigating life's journeys in the presence of tasty temptations.

- The effects of fast food consumption on our brains extend beyond obesity, potentially impairing neurobiological functions like spatial memory and navigation.
- In a study, participants who frequently consumed fast food, such as burgers or soda, struggled more with remembering routes and navigator mistakes, even when accounting for mental health, nutrition, and weight.
- Adopting a healthier diet, with a focus on vegetables, fruits, whole grains, and nutritious fats, could help reverse these detrimental effects on cognitive function, specifically the hippocampus.
- Short breaks for physical activity during intellectual work or study, which stimulate the release of myokines, can also have a positive impact on brain function and learning.
- Maintaining a balanced diet and embracing fitness-and-exercise and health-and-wellness principles isn't just beneficial for our physical appearance; it's also essential for the long-term health of our brains, aiding in mental-health, memory, and navigation abilities.
