CDC finds ultra-processed foods account for 55% of calories consumed by Americans, with burgers, sweet bakery items, and savory snacks as top sources.

Roughly 55 percent of the average daily caloric intake comes from ultra-processed foods, which HHS Secretary Robert F. Kennedy Jr. has vowed to crack down on.

Most Americans get more than half their calories from ultra-processed foods, those super-tasty, energy-dense foods typically full of sugar, salt and unhealthy fats, according to a new federal report. Nutrition research has shown for years that ultra-processed foods make up a big chunk of the U.S. diet, especially for kids and teens.
