A lecture by Kurt W. Donsbach, Ph.D. The traditional treatment for diabetes is the injection of insulin. But the founder of Donsbach University, School of Nutrition, tells how to stimulate the body into producing more of its own insulin by a combination of exercise, supplemental zinc, and a readily available substance called GTF (Glucose Tolerance Factor). This combination allows many diabetics to reduce their need for artificial insulin or to eliminate it altogether. Specialized nutrition is the key. 45 min. audio cassette.
