I share your sentiment of frustration. I've read "The China Study" by Campbell and various other articles about paleo-diet and others and there is a lot of contradictory informations.

Although they go in opposite directions (Campbell advocates vegan, paleo meat), they seem to agree on at least one thing : unprocessed foods are better. Eat vegetables, fruits, whole grains and meat/fish, but avoid sauces/butter, sodas, white bread and various candies.
