Canada study links ultra-processed foods to brain injury

A Canadian study involving approximately 9,000 healthy adults aged 35 to 69 has linked the high consumption of ultra-processed foods (UPF) to increased risks of subtle, asymptomatic brain damage.

Published in JAMA Network Open, the research utilized MRI scans to identify vascular brain injuries, including white matter hyperintensities and silent, symptomless small strokes. Participants in the highest consumption group—those eating products like sugary cereals, soft drinks, and packaged snacks—showed a 40% higher likelihood of these brain changes compared to those with the lowest intake.

The study also noted a correlation between high UPF consumption and increased levels of body fat, particularly visceral fat, which is associated with inflammatory processes and vascular damage. While the findings suggest a connection between diet and early neurological changes, researchers emphasized that the study does not prove direct causation and called for long-term observational studies to determine if dietary changes can reverse or slow these effects.
