Carbs aren't the problem. Toxic foods are the problem. The fact that wheat is a starch is meaningless. Wheat is bad because it contains, gluten, WGA, phytic acid, a host of other bad lectins and very little nutrition (it's empty calories). That being said, human beings aren't made to eat sawdust. I would much, MUCH rather eat sourdough wheat bread than that poisonous garbage. Sourdough bread far more closely resembles food than that brick.
