A newly published study in Neurology has investigated the potential link between ultra-processed foods (UPFs) and early signs of Parkinson’s disease, sparking reactions from leading researchers in the field who praised the study’s scale but advised caution in interpreting its findings. Professor Jules Griffin, director of the Rowett Institute at the University of Aberdeen, UK, highlights the study’s significance in exploring how diet could be tied to impact brain health. “We’ve known for some time that unhealthy diets can contribute to vascular dementia and Alzheimer disease.”
