The Incredible Edible Egg: History of the Longest-Running Food Slogan

In 1977, the American Egg Board launched an advertising campaign built around a four-word slogan that would outlast most of the marketing professionals who created it. "The Incredible, Edible Egg" was not an attempt to introduce Americans to a new food. It was a defensive campaign, designed to counter a specific and serious commercial threat: the emerging scientific and media consensus linking dietary cholesterol, found in significant quantities in egg yolks, to cardiovascular disease. The campaign's longevity reflects both the effectiveness of the slogan and the complexity of the nutritional science it was designed to address. ## The American Egg Board and Checkoff Programs The American Egg Board was established under the Egg Research and Consumer Information Act of 1974, which created a producer-funded promotional program, known in agriculture as a "checkoff" program, for the egg industry. Under checkoff programs, egg producers pay a small assessment per case of eggs sold, and the funds are pooled for generic industry promotion and research. The USDA oversees the program. The Egg Board does not promote any individual brand or producer. It promotes eggs. The "Incredible, Edible Egg" campaign was one of the Egg Board's first major national advertising investments. The slogan was created to be memorable, positive, and content-free in the sense that it made no specific health claims that could be challenged by regulatory agencies. "Incredible" and "edible" are both accurate and unverifiable as marketing assertions. The campaign ran on television with jingle-based ads that made the slogan into an earworm recognizable across generations of American households. ## The Cholesterol Wars The campaign's context was the emerging dietary cholesterol debate. The Seven Countries Study, conducted by Ancel Keys and published in various forms through the 1950s and 1960s, had established in the scientific mainstream the idea that saturated fat and dietary cholesterol contributed to cardiovascular disease. Eggs contain approximately 186 milligrams of cholesterol per yolk, and they became one of the primary targets of public health messaging urging Americans to reduce dietary cholesterol intake. The Egg Board's response, funded by the "Incredible, Edible Egg" campaign and subsequent promotions, was partly marketing and partly research investment. The Board funded studies examining the relationship between dietary cholesterol and blood cholesterol levels, research that ultimately contributed to a genuine scientific reexamination of the question. By the 2010s, the scientific consensus had shifted significantly. The 2015 Dietary Guidelines Advisory Committee removed the specific numerical limit on dietary cholesterol that had governed federal nutrition recommendations since the 1960s, citing insufficient evidence that dietary cholesterol directly raises cardiovascular risk in most people. The slogan survived cholesterol debates, multiple reformulations of the campaign, and decades of nutritional politics. It was retired and revived multiple times. The American Egg Board relaunched it in 2013 after a period of using different messaging, citing consumer research showing that the original slogan retained recognition among Americans who had not been born when it first aired. A marketing phrase created to defend eggs against a scientific controversy has outlasted the controversy itself.
