Okay, you guys are into university research.
This is what The University of Vermont says about spelt:
Spelt is a grain that has come up in recent discussions about whole grains. Spelt is an ancient grain that dates back to the Neolithic era (The New Stone Age), 10,000 B.C. Spelt is one of the three ancient wheat varieties; the other two ancient varieties are emmer and einkorn. What a history! These grains grew wild and once people figured out that they could plant the seeds, communities were formed and ended some of the nomadic wandering in search of food.
Wilder versions of plant foods are considered healthier by natural health folks, as they are less man-made and more natural.
