Agree with all three of your nutritional points. But see, the reason why paleo would be an improvement for most people is because it excludes garbage food like twinkies and ice cream, so right there most people are going to benefit. This is a testament to the harmfulness of refined junk foods more so than to the efficacy of the paleo diet. Any well balanced diet that excludes junk foods is going to yield the same improvement, this is not something unique to paleo. Paleo goes a step further and artificially restricts the breadth of healthy food options that people should eat, by arbitrarily labelling any foods that are traditionally farmed and/or refined (legumes, grains, rolled oats, potatoes, protein powder, etc.) as automatically bad for no reason other than our neanderthal ancestors did not eat them. This is misguided thinking.
