Opposition to ultra-processed foods is gaining steam worldwide. This includes things like frozen pizza, potato chips and other mass-produced goods made with industrial ingredients and additives. Scientists are studying why diets high in ultra-processed foods have been tied to health problems, and potential policy changes are under review ahead of the next dietary guidelines, set to be released in 2025. Every-five-years advice from regulators on what Americans should eat are published, and ultra-processed foods are facing increased scrutiny as they have an outsize role in American diets. Food-industry proponents argue less processing could lead to more food waste, higher prices, along with less accessibility and convenience.
