Description
PET scans show the higher brain activity of a 50-year-old woman on a Mediterranean-style diet (left, image shows more red, which indicates higher activity) and a 50-year-old on a Western diet most of her life (right, image shows much less red). Arrows point to areas that are typically affected by Alzheimer’s disease, with lower activity for Western diet.
