Gorillas and diet at the Cleveland Metroparks Zoo.  Both Gorillas have heart disease.  I find it very interesting that as the sugar in their diet went down, behaviors not observed in the wild (but observed in captivity) went down.    Let’s do a study on decreasing sugar in children’s diet, increasing vegetables, in a population of students that is high in behavior problems and observe the changes in behavior their.  Oh wait, that’s been done a lot.
