Boxed cereal, once the king of American breakfast tables and a defining fixture of Generation X childhoods, is rapidly losing appeal, especially among Gen Z, who seem to be trading their cereal spoons for smoothies, eggs, and mental clarity.

United States cereal sales have steadily declined for more than 25 years. A brief pandemic-era uptick couldn’t stop the slide: According to NielsenIQ, cereal sales dropped over 13% from nearly 2.5 billion boxes in 2021 to just 2.1 billion this year.
