Raisin Bran cereal was first introduced in the United States in 1926 by U.S. Mills. The name "Raisin Bran" was at one time trademarked but widespread use of the term to refer to any bran-and-raisin cereal caused it to become genericized, so that it can no longer be subject to trademark protections.
Today, the best-known cereal brand is Kellogg's Raisin Bran, introduced in 1942. It is known for its cereal advertising slogan, "Two scoops of raisins in Kellogg's Raisin Bran", and its mascot, an animated sun named "Sunny". Kellogg's now also markets a variety called Raisin Bran Crunch, which contains crunchy oat and honey clusters. Raisin bran cereal is touted for its high dietary fiber content, but sometimes criticized for containing too much suagr. Raisins naturally contain high levels of fructose. In addition, to prevent clumping many manufacturers add sugar to the raisins; as of January 7, 2010, Kellogg's adds high-fructose corn syrup to its Raisin Bran cereal. These raisins account for more than 60% of the weight of the cereal.
