It's no secret that junk food is bad for your health.

Now, a new study from the UNC School of Medicine is offering fresh insight into how junk food may quietly reshape the brain. Published in Neuron,

one of the most influential journals in the field of neuroscience, the research shows that diets high in processed snacks can actually rewire the brain’s memory center, significantly raising the risk of cognitive issues over time.

These findings could help pave the way for early interventions that protect memory and brain health, especially for those struggling with obesity. It’s also a powerful reminder that what we eat directly affects how we think, remember, and feel.
