Proteins and various nutrients are the building blocks of the machine that is your body, and carbohydrates are the fuel upon which it runs. There is a large and growing minority of people who can't metabolize gluten, with symptoms ranging from intestinal discomfort to cardiac arrest, and when they take that seriously I understand them. When they say that I would be better off without wheat they're wrong. Everyone is different, that's evolutions way of guaranteeing that someone survives in the event of an ecological change. The Paleodiet concept is neat, but doesn't take into consideration that humans have been evolving with their dietary constraints for all of evolutionary history and that includes the last 10,000 years of agriculture. 99.99% of the populaiton was once lactose intolerant, but economic conditions favored dairy farming in Europe and within a few dozen generations the overwhelming majority of the European population was able to metabolize lactose, the sugar in milk. African, Asian and New World populations couldn't and their majority still can't. If a paleo diet works for you, great, but don't close off the innovations of the entire holocene without a good reason.
