According to data from IRI, Chicago, sales of frozen pizza were up about 1.15 percent in the 52 weeks ending August 7, 2016, representing about $4.5 billion. Unit sales, though, were down about 2.14 percent. Why?

Frozen foods and snacks are meeting no shortage of challenges in the marketplace according to the “Frozen Foods in the U.S.: Hot Meals, Sides, and Snacks” report from Packaged Facts.

With Americans eating more of their meals on the go, it’s no surprise that breakfast is increasingly consumed behind the steering wheel, on the train or at the office.

American takeout standbys like pizza and Chinese food should watch their backs, because Mexican cuisine is close behind, says the “Global Palates 2015” report from the National Restaurant Association.

When it comes to sweet goods like doughnuts, Danishes, sweet rolls, muffins and coffee cake, the market is in a state of flux. As Walter Postelwait, president of Pak Group LLC/Bellarise Baking Ingredients, Pasadena, CA, puts it: “The total segment appears to be growing slowly, but has hot pockets of activity.”

With current food trends focusing on health-and-wellness, it may be tempting to dismiss the cookie category as out of touch or on its way out. And while most of the top companies operating in the cookie category have seen relatively flat sales activity—or, at best, modest gains—traditional cookies still account for a sizeable portion of this $8 billon category.
