Packaged food manufacturers in North America have seen relatively little pushback from consumers despite multiple rounds of price increases this year, as high inflation drives people to cook at home rather then spend on eating out.

"Through a combination of inflation-driven pricing actions and productivity improvements, we have substantially mitigated significant inflationary pressure in the quarter," Campbell Soup Chief Executive Officer Mark Clouse said.

Campbell's upbeat results follow those from Kellogg, General Mills and Kraft Heinz, who have in recent months said that several rounds of price increases have not yet dented demand for their products significantly.

Still, even though groceries and essentials are among the last to see a drop in demand during economic downturns, analysts warn that companies such as Campbell could soon start to suffer as lower-income and elderly shoppers switch to cheaper store-brand products.
