Whole grains and refined are the same. Sort of. Refined grains are devitalized and nutritionally worthless. Whole grains have all their anti-nutrients binding to all the nutrients they do have. Functionally, they end up nutritionally similar since one has nothing and one is not giving up anything it has. Then one can say that refined is worse because of the glycemic spike or that whole is worse because these toxins may interact with other things in your body and cause other problems.
