Ultra-processed Foods Damage Your Focus Even if You Eat Healthily

New research from Monash University, the University of São Paulo, and Deakin University reveals that a diet high in ultra-processed foods can impair the brain's ability to concentrate and increase dementia risk, regardless of other healthy eating habits. The study, published in Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring, analyzed dietary patterns and cognitive health in over 2,100 Australian middle-aged and older adults without dementia. Findings suggest that heavily processed foods may have independent negative effects on cognitive function and brain health. This research underscores that simply adding healthy foods to your diet may not fully offset the harmful impact of ultra-processed food consumption. Healthcare professionals recommend reducing processed food intake as part of a comprehensive strategy to protect long-term brain health and reduce neurodegenerative disease risk.
