Wild Rice is roasted/parched but it is still a “whole grain” because the bran layer, endosperm and germ (all have to be present to qualify as a whole grain ) are present in wild rice. White rice IS NOT a whole grain as it has had the bran layer and germ removed. Brown rice and colored rice are whole grains.
