I did some reading on the caveman/paleo diet. The theory behind it seems sound...We all come from cavemen and cavemen ate meat and didn't cook their veggies so our bodies aren't designed to digest foods that have to be cooked to be consumed. The problem with this approach is the limiting nature of the diet. Variety in foods is one of the things that has gone a long way toward extending lifespan. If you believe the whole descended from Cromagnon thing then this diet falls apart when you consider the fact that the only goal during that time was to live long enough to reproduce and "old age" was living into your thirties (cholesterol and atherosclerosis aren't much of a concern when being gored to death by a mammoth in your twenties is more likely) That being said, this diet isn't without merit. The strict avoidance of processed foods is always a good idea and seems to be a consistent theme to most current dietary modification (not dieting).
