I was just wondering why starchy vegetables like roots and tubers are not allowed on paleo diets. As far as I can tell (from reading other sites) is because they can't be eaten raw. But isn't it only potatoes that can't be eaten raw? I knew a girl who ate raw sweet potatoes all the time. Also, homo erectus was the first hominid to use fire and they existed 1.8 - 1.3 mya. We are the not the same genetically or biologically as erectus and we have adapted slightly to the use of fire - our digestive systems have become slightly shorter etc.
Or are they not recommended because it is of the high carbohydrate content of those foods?
Any help would be greatly appreciated. Thanks, Hannah
