It said if you can GROW it. Then you can eat it. To my knowledge sweet potatoes are not processed anywhere but come from the ground. I believe they're Paleo but I am no expert

sounds great but I have read a little more about this diet under the link you have posted at the beginning of the article and I am confused now...because many of the foods I see here are under NOT ALLOWED there...

Sweet potatoes are a perennial starch not an annual grain and most certainly paleo-OK as they came long before the use of irrigation and acgriculure for man to eat it. And in all honesty, who really cares? These meals are rather bland even of paleo. Chicken and broccoli? C'mon.

Sweat Potatos are on the Primal Blue Print

Thats helpful. who cares
