Konjac is a root. So, yes it is Primal. The "noodles" however, are just about pure dietary fibre. They'e OK but they can cause digestive system stoppage if you eat too much at once. I prefer Sea Tangle brand kelp noodles for a pasta substitute. Both are equally flavorless but good for soaking up the sauce. The kelp needles have some nutritional value as well being a very good source of iodine.
