For more resources on the topic I suggest a few books.
http://www.primalbody-primalmind.com/ - Primal Body Primal Mind by Nora Gedgaudas – Lots of science.
http://www.marksdailyapple.com/ - Primal Blueprint by Mark Sisson – Lot more accessible. Give it to your parents etc.
http://www.amazon.com/Good-Calories-Bad-Gary-Taubes/dp/14000... - Good Calories, Bad Calories by Gary Taubes – Very long, but explains where the American Dietary guidelines came from and why they are wrong. (Cliffs notes: http://higher-thought.net/complete-notes-to-good-calories-ba... )
