It is turning out that the fast food high fat Standard American Diet (SAD) has, in fact, some pretty sad impacts on the brain besides the waistline.
The New York Times reported that the Society for Neuroscience met in New Orleans and University of Minnesota scientists demonstrated that a group of rats that consumed normal food for four months compared favorably with a group of rats that ate a diet with 40 percent fat in it. Both diets had the same amount of calories.
The scientists administered a memory test to the rats after four months. Those with the normal diet performed as they had previously while those on the high-fat diet yielded much poorer results.
The rats were then broken into two groups. One group had running wheels. The other didn’t. So, those on the high fat diet could or could not exercise.
