Grape Nuts is a breakfast cereal made from whole grain wheat and barley. It was created in 1897 by Charles W. Post, an American inventor and entrepreneur. The cereal is known for its crunchy texture and nutty flavor, and it is often enjoyed with milk or yogurt. Despite its name, Grape Nuts does not contain grapes or nuts. The name comes from the flavor of the cereal, which is said to resemble the taste of grape sugar, and the "nut" refers to its crunchy texture. Grape Nuts is a source of fiber and is often marketed as a healthy breakfast option.
