Cereal industry ponders future as U.S. appetites change
Cereal industry ponders future as U.S. appetites change

Americans aren't eating breakfast like they used to.

It's no secret that Greek yogurt's popularity is on the rise and consumers are increasingly losing their appetite for cereal. But recent data show the trends are picking up speed and creating major headaches for some of the companies behind America's best-known breakfast brands.

General Mills (NYSE:GIS - News) on Wednesday reported sales that came short of analysts' estimates, in part due to consumers' changing breakfast habits.

Here are three ways Americans are fundamentally taking a different approach to their first meal of the day, and who may be the winners and losers in the shift in breakfast habits.

Cereal sales and volumes have been steadily declining for more than a year, with sales falling 7 percent in the latest four-week period, according to Nielsen ScanTrack data.

Kellogg (NYSE:K - News), which relies on cereal for about 30 percent of its total sales, got hit the hardest, with cereal sales down 10 percent for the period. It was followed by private label General Mills, which gets about 20 percent of its sales from cereal; Post (NYSE:POST - News), which puts out cereals such as Grape-Nuts and Fruity Pebbles; and PepsiCo (NYSE:PEP - News), which owns Quaker.

To combat the decline, brands are introducing new products and trying to get the message out that cereal is healthy.

Kellogg, which most recently cited weakness in its Special K, Frosted Mini-Wheats and Kashi brands, is working to improve consumers' perceptions by what it calls "health-related messaging." It's trying to remind consumers that cereals can be a source of protein, which is popular right now and among the reasons yogurt and meat sales have surged.

As Kellogg CEO John Bryant noted on the first-quarter conference call in May, the company is finding that consumers don't realize that in "a bowl of Mini-Wheats and milk, there's as much protein as in many yogurts."

He called it an "opportunity to reappraise and reconsider cereal and milk" for breakfast consumers.

Kellogg is also trying to pivot to healthier, buzzier products such as non-GMO verified Kashi and new cereal snacks that capitalize on the growing snacking trend. Bryant said he expects cereal consumption to continue to decline, but at a more moderate rate, for the rest of the year.

General Mills has also invested in advertising campaigns to raise awareness about the nutritional benefits of cereal and is emphasizing its Yoplait yogurt portfolio that includes Yoplait Greek. The company raised expectations on Wednesday citing product upgrades, including more cinnamon taste in Cinnamon Toast Crunch and fruitier tasting Trix.
