What breakfast cereal was named after a substance it never actually contained?

Question

Accepted Answer

Grape-Nuts

When C.W. Post introduced Grape-Nuts in 1897, he was riding high on the success of his coffee substitute, Postum. The cereal was originally marketed as a health food during America's sanitarium craze, when wealthy patients flocked to facilities like John Harvey Kellogg's Battle Creek retreat seeking wholesome alternatives to heavy Victorian diets. Post, a former patient himself, understood the power of pseudoscientific marketing.

The name was pure promotional genius—or pseudoscience, depending on your perspective. Post claimed that during the baking process, the starch in his wheat-and-barley nuggets transformed into a form of glucose he called "grape sugar." The "nuts" part referred to the cereal's nutty flavor and rock-hard texture. Neither claim held up to scrutiny, but in an era before truth-in-advertising laws, it didn't matter. Post wrapped his product in the language of health reform, claiming it could cure appendicitis, malaria, and even loose teeth.

The cereal became a massive success despite—or perhaps because of—its notorious hardness. Jokes about breaking teeth on Grape-Nuts have persisted for over a century. Consumers learned to soak it in milk overnight or bake it into bread. Post's competitors accused him of creating "digestive gravel," but Americans bought it by the trainload, making Post a multimillionaire.

Today, Grape-Nuts endures as one of America's oldest continuously produced cereals, its absurd name now protected by trademark law and embraced as vintage Americana. The Federal Trade Commission would never allow such a name today, but Post's 1897 gambit remains a masterclass in memorable branding—even when the name makes absolutely no sense.
