WHEN we became Seventh-day Adventists we soon realized that Adventists taught, although not all practiced, some rather unique health principles. Gradually we began to accept and practice many of these, but it was not until I became a student at the Loma Linda University School of Health that I really began to understand the scientific and Biblical backgrounds for these health practices. Prior to this, Adventists told me, "Oh, this isn't good for you" or "It's all right to eat this." But nowhere had I heard an explanation of why it was or wasn't good that really satisfied me. . .
