Fatty Foods affect not only exercise but also MEMORY http://well.blogs.nytimes.com/2009/08/13/fatty-foods-affect-memory-and-exercise/. We hear everyday we need to be eating healthier. Eating healthier and having an active lifestyle makes your body and mind feel better. I always thought it was a mental thing because your body feels good and you sleep better causing your mind to feel refreshed. This new research on rats and people showed it is more than just that. High fat diets changed the memory of rats in just 4 days! Humans did not take much longer. I guess our moms’ were always right when they told us to eat our vegetables!
