Scarring in brain
Seems to me that it is the "over-use" of fatty foods that cause scarring. In fact fatty foods are necessary to help normal brain function and growth. To have a headline that states that "Fatty Foods Cause Brain Scarring" is misleading to say the least. It is my understanding that Americans are probably the most obese people in the world(1). They got that way by listening to their government telling them to eat more carbs and less fat. Eating carbs does not satisfy food cravings as much as eating fat but still causes the body to put on more fat.
