Ultra-processed food consumption linked to brain damage in middle-aged adults
A study published in JAMA Network Open has linked high consumption of ultra-processed foods (UPFs) to increased signs of brain damage in healthy middle-aged adults. Researchers from McMaster University and Hamilton Health Sciences analyzed nearly 9,000 Canadian adults aged 35 to 69 using magnetic resonance imaging (MRI).
Findings indicate that individuals with the highest intake of UPFs—such as packaged snacks, sugary cereals, soft drinks, and ready-to-eat meals—were 40% more likely to show small, asymptomatic brain lesions compared to those with lower consumption. These lesions are considered early warning signs that may precede clinical strokes or memory and cognitive issues.
The research noted that the association was particularly strong among women. Additionally, participants with higher UPF consumption tended to have greater amounts of body fat and deep abdominal fat, which are linked to inflammation and vascular damage. While the study demonstrates a significant statistical association, researchers emphasized that it does not prove direct causation.
