The main message behind the paleo lifestyle is nutrient density or just simply proper food. As far as grains go, they are for the most part off menu due to their processing, additives, insulin spiking, anti-nutrient, gluten profile. However, sprouted grains are a different beast altogether, as they are, according to some, one of the most nutrient rich foods available. I don't know if they are considered paleo though as buckwheat is accepted, an older grain and gluten free. I went paleo-ish to discover in my middle age that I have a gluten sensitivity/tolerance issue after a process of elimination and self experimentation, so I'm not going to be critical of the paleo movement but would agree that somewhere, somehow, the very word paleo is now used as a marketing ploy in much the same way as 'organic', 'gluten free' and/or other 'health' products. And products they are.
Interesting here in the uk last night a documentary on red meat eating featured a doctor as a narrator who ate a high-ish quantity of meat over 1 month. Health checks before and after revealed he got fatter, cholesterol was up, BP up etc with the conclusion that excess meat, for a whole load of possible reasons, results in a possible early death. Yet all the footage of him chowing down his meat diet consisted of him eating his burger in a bun, bacon in bread, munching deep fried (no doubt in veg oil) onion rings with no mention that his grain quota was up too! A variable that was totally by-passed. Why is it that a non scientist and lay person can spot this, yet a BBC science documentary featuring a doctor doing the actual study and various Harvard profs fail to mention? Did nothing to shift me from my meat and 4 veg.
