answer:“Whole wheat” flour means that the whole plant is put into the stuff. “Whole grain” is literally the whole grain, unpulverized. Not flour. I think, that’s how it works, anyway. When you take any starchy edible plant, pulverize it into powder, you’re going to end up with similar products regardless of what you use. I don’t know which one would be healthier, though. I’d imagine the coconut would be, because it can be eaten raw while the wheat requires cooking before its toxicity is low enough to digest. I’d go with coconut on that principle alone.
