Food Processing: Criteria for Dietary Guidance and Public Health?

The NOVA food classification advises avoiding ultra-processed foods (UPF) to combat obesity, but its non-traditional criteria—like ingredient count and additives—diverge from standard definitions. Evidence linking UPF to poor nutrition may reflect circular logic, as added sugars help define UPF. Avoiding UPF could reduce key nutrients from foods like fortified breads or flavored milk. NOVA’s practicality, clarity, and effectiveness for consumers remain untested and unproven compared to established dietary models. Further research is needed to assess its usability and health impact.
