You’ve probably heard that “breakfast is the most important meal of the day.”
What you may not know is the origin of this ode to breakfast: a 1944 marketing campaign launched by Grape Nuts manufacturer General Foods to sell more cereal.
During the campaign, which marketers named “Eat a Good Breakfast—Do a Better Job”, grocery stores handed out pamphlets that promoted the importance of breakfast while radio advertisements announced that “Nutrition experts say breakfast is the most important meal of the day.”
Ads like these were key to the rise of cereal, a product invented by men like John Harvey Kellogg, a deeply religious doctor who believed that cereal would both improve Americans’ health and keep them from masturbating and desiring sex. (Only half of his message made it into the ads.)
