Dixie Carb CountersFood Thickener - Low Carb Potatoes

First, is this just the one bag? second, why on earth is this so expensive? you remove carbs and jack up the price?

Even dehydrated their still potatoes? correct? I dont understand how dehydrating would change what it is

Are these gluten-free? I saw wheat-free somewhere. The fact that they say wheat-free but not gluten-free and have cereal fiber in them scares me.

Is this keto proof?
