paleo plant nutrient levels

One thing I don't hear anyone talking about in regards to the paleo diet is this:  ancient vegetable foods were small compared to today which means much higher surface area to volume.  This means lower carbs to nutrient ratio (including proteins).  Strawberries 1/4 today's radius would have 4 times more seeds (on the surface) per calorie.  Grapes 1/3 the current radius would have 3 times the surface area per carb, containing most of the sun-hardened colorful phytochemicals including resveratrol.
