The danger of sugar highs

I recently listened to a recorded lecture by Dr. Aajonus Vonderplanitz (no joke, that is his name) on the "primal diet" which incorporates raw foods and even raw meat into the diet and downplays the body's needs for sugars, even those from fruit. What I found especially interesting and even scary was what he said about fruit sugar. Dr. Vonderplanitz described that when killer monkeys prepare for the hunt, they consume ripe bananas in order to get a sugar high that enables them to go on a killing spree. The sugar in the bananas causes them to be able to go on this killing spree, giving them the energy to almost "go crazy" and be able to kill anything in their path. Think about this next time when reaching for a can of coke, bag of gummy bears or even more than one half of a ripe banana.
