Coca-Cola, PepsiCo, and General Mills are facing criticism from Senate Democrat Elizabeth Warren and Representative Madeleine Dean, who allege that these companies are exploiting consumers through shrinkflation practices.

In separate letters sent to the CEOs of each company, Warren and Dean condemned the strategy of increasing profits by decreasing product sizes, such as those of sodas and cereals.

The lawmakers stated, “This price gouging is unfortunately a pervasive issue, with corporate profits contributing to more than half of inflation,” in their correspondence with the executives.

They requested that Coca-Cola and PepsiCo disclose the average annual price per ounce of their soda products from 2018 to 2024, while General Mills was asked to provide similar data for its cereal products over the same period.

PepsiCo has chosen not to comment, and Coca-Cola and General Mills have yet to respond to inquiries for comment.
