 Wheat is the primary grain used in U.S. grain products. Approximately three-quarters of all U.S. grain products are made from wheat flour. The first bagel rolled into the world in 1683 when a baker from Vienna, Austria, was thankful to the King of Poland for saving Austria from Turkish invaders. The baker reshaped the local bread so that it resembled the King's stirrup. The new bread was called bugel, derived from the German word for stirrup.
