Breakfast cereal sales declined for decades before Kellogg's sale to Italian company

Breakfast cereal could use a lucky charm.
U.S. sales of the colorfully packaged morning staple have been in a decades-long decline, a trend back in the spotlight with news that Italian confectioner Ferrero Group plans to purchase the American company that makes Kellogg's Corn Flakes, Froot Loops, Rice Krispies and other familiar brands.
Except for a brief period during the coronavirus pandemic, when many workers were home and had time to sit down with a bowl of cereal and milk, sales of cold cereal have steadily fallen for at least 25 years, experts say.
In the 52 weeks ending July 3, 2021, Americans bought nearly 2.5 billion boxes of cereal, according to market research company Nielsen IQ. In the same period this year, the number was down more than 13% to 2.1 billion.
Cereal has been struggling for multiple reasons. The rise of more portable options like Nutri-Grain bars and Clif Bars – which both went on sale in the early 1990s – made it easier for consumers to grab breakfast on the go.
Concerns about food processing and sugar intake have also dimmed some consumers' enthusiasm for cereals. One cup of Lucky Charms contains 24% of a consumer's daily recommended intake of sugar, for example.
'Cereal finds it really hard to get out from underneath that,' said Tom Rees, global insight manager for staple foods at the consulting company Euromonitor. 'It can't escape the fact that it doesn't look like a natural food. You have to create it and form it.'
Rees noted that for decades, cereal manufacturers focused on adding vitamins and minerals to build cereal's health credentials. But consumers now are looking for simplified ingredient lists.
Artificial dyes — like the petroleum-based colors that brighten Froot Loops — have also come under fire. Last fall, dozens of people rallied outside WK Kellogg's Battle Creek, Michigan, headquarters demanding that it remove artificial dyes from its cereals. Kellogg and General Mills — another major U.S. cereal maker — have since pledged to phase out artificial dyes.
Add to that, consumers are expanding their idea of what breakfast can be. Yogurt and shakes have replaced the traditional bacon and eggs. Kenton Barello, a vice president at the market research firm YouGov, said his polling shows that Generation Z consumers, who were born between 1997 and 2007, eat more vegetables for breakfast than other generations.
Barello said YouGov's polling also shows that members of Gen Z are less likely to eat breakfast but still buy ready-to-eat cereal, suggesting they're eating it as a snack or for other meals.
'With younger generations, there are differences in their relationship with food and these eating moments,' Barello said. 'They are going about breakfast in a different way than Millennials, Gen X and Baby Boomers.'
Cereal's struggles are part of what led to the breakup of the Kellogg Company. In 2023, the century-old company that put Battle Creek, Michigan, on the map split into two companies. Kellanova took popular snack brands like Cheez-Its, Pringles and Pop-Tarts as well as international cereals, and WK Kellogg made cereals for the U.S., Canada and the Caribbean.
In 2024, M&M's maker Mars Inc. announced a plan to buy Kellanova for more than $30 billion. That plan has cleared U.S. regulators but is still awaiting regulatory approval in Europe. WK Kellogg was left to try to rejuvenate the cereal business.
The sale of WK Kellogg to Ferrero doesn't mean supermarket cereal aisles are at risk of extinction. Packaged food companies have options for turning around their soggy cereal sales, Rees said. He thinks Kellogg's Mashups line, which mixed brands like Frosted Flakes and Froot Loops into one box, appeal to younger consumers, who tend to like interesting flavor combinations.
The market may also have a fragmented future, according to Rees. Companies may have to accept that younger buyers want a sweet-and-spicy cereal while older buyers might want a Keto-friendly option.
'The future might be realizing that the era of 'This brand will serve everybody' isn't going to happen,' Rees said.
Julia Mills, a food analyst with the consulting company Mintel, thinks the shrinking population of children in the U.S. gives cereal makers the opportunity to shift to more sophisticated flavors and packaging. Cereal could be positioned as a fancy topping for yogurt, for example, or a fiber-rich food that can improve gut health.
Some niche cereal brands, like high-fiber Poop Like a Champion cereal and high-protein, zero-sugar Magic Spoon, are already doing that. But legacy brands say they shouldn't be counted out.
Jeffrey Harmening, the chairman and chief executive officer of Cheerios maker General Mills, said his company considered trying to acquire Magic Spoon. Instead, it made high-protein versions of Cheerios, which now outsells Magic Spoon.
'The key to longer term is, honestly, is giving consumers more of what they want,' Harmening said during a conference call with investors in March.
