<Tr> <Th> Website </Th> <Td> GrapeNuts.com </Td> </Tr> <P> Grape - Nuts is a breakfast cereal developed in 1897 by C.W. Post, a former patient and later competitor of the 19th - century breakfast food innovator, Dr. John Harvey Kellogg . The cereal originally prepared by C.W. Post when developing the product was a batter that came from the oven as a rigid sheet . He then broke the sheet into pieces and ran them through a coffee grinder to produce the "nut" sized kernels . </P> <P> Despite the name, the cereal contains neither grapes nor nuts; it is made with wheat and barley . Post believed that glucose (which he called "grape sugar") formed in the baking process . This, combined with the nutty flavor of the cereal, is said to have inspired its name . Another explanation originates from employees at Post, who claim that the cereal got its name due to a resemblance to grape seeds, or grape "nuts". </P> <P> Grape - Nuts was initially marketed as a natural cereal that could enhance health and vitality, and as a "food for brain and nerve centres ." Its lightweight and compact nature, nutritional value, and resistance to spoilage made it a popular food for exploration and expedition groups in the 1920s and 1930s . In World War II, Grape - Nuts was a component of the lightweight Jungle ration used by some U.S. and Allied Forces in wartime operations before 1944 . </P>
