Consuming fast food regularly? Study reveals SHOCKING aftermath

Who doesn’t like to have a bit of a burger and a few fries once in a while! If there’s a glass of chilled soda or some cold drink, the meal is a happy one! And what else can it make it better if not a chunk from a sugar-laden doughnut to finish it off with!

Even the idea of this meal is a tempting one.

But, do you know, how much does this one meal cost to your health?



Read on to find out.


In a significant study, researchers have linked fatty and sugary diets to impaired cognitive function.


What insights does the study provide?

A research team from the University of Sydney conducted an in-depth examination of the connection between high-fat, high-sugar (HFHS) diets—specifically those rich in refined sugars and saturated fats—and the ability to navigate spaces effectively in a first-person perspective. Spatial navigation refers to the cognitive ability to learn and remember routes from one place to another, an essential function linked to the health of the hippocampus, a critical brain structure involved in memory and navigation. This study was published in the esteemed *International Journal of Obesity*.


Dr. Dominic Tran, a key researcher from the Faculty of Science’s School of Psychology, spearheaded the study, which revealed that HFHS diets adversely affect various aspects of cognitive function. Notably, these detrimental impacts seem to particularly focus on the hippocampus rather than compromising cognitive abilities throughout the entire brain.

“The encouraging takeaway from our findings is that the situation is likely reversible,” Dr. Tran stated. He highlighted that dietary modifications can enhance hippocampal health, subsequently improving our navigational skills—vital for activities like exploring unfamiliar cities or finding new routes home.


Key findings of the research:

The research involved a cohort of 55 university students, all aged between 18 and 38 years. Participants were asked to complete comprehensive questionnaires that detailed their consumption of sugary and fatty foods. Additionally, their working memory was assessed through a series of recall exercises, and their body mass index (BMI) was measured to provide context for their cognitive performance.


The core of the experiment required participants to navigate through a simulated virtual reality maze, tasked with locating a treasure chest in six separate trials. This maze was designed with distinct landmarks, which participants could utilize to orient themselves. Each trial maintained a consistent starting point and a fixed location for the treasure chest to ensure reliable results. If participants located the treasure within four minutes, they would promptly proceed to the next trial. Conversely, if they failed to find it within the allocated time, they were teleported to the treasure’s location and given 10 seconds to familiarize themselves with that specific spot before the subsequent trial began.

Analysis of the data showed a marked difference in performance: those participants with lower intakes of fats and sugars demonstrated a significantly higher accuracy in identifying the treasure’s location compared to their counterparts who indulged in these foods multiple times per week.

“After accounting for variances in working memory and BMI, which we measured independently from the experimental tasks, we found that a participant’s sugar and fat consumption was a consistent predictor of their success in the final, seventh test,” Dr. Tran elaborated.

Dr. Tran emphasized the critical importance of making thoughtful dietary choices in order to support optimal brain function. It has long been recognized that excessive consumption of refined sugars and saturated fats poses risks for obesity, metabolic and cardiovascular diseases, as well as certain cancers. Furthermore, unhealthy eating patterns are known to accelerate age-related cognitive decline in middle-aged and older populations.

“This research provides compelling evidence that diet significantly influences brain health during early adulthood—a crucial developmental period when cognitive capabilities are typically robust,” Dr. Tran concluded.
