American Journal of Public Health Series on Ultraprocessed Foods: My Editorial

Key Takeaways

• New US Dietary Guidelines advise limiting highly processed foods
• Fed UP! campaign seeks policy tools to curb ultraprocessed intake
• Trial shows ultraprocessed diet adds ~500 calories daily
• Industry ties raise concerns about guideline integrity and capture

Pulse Analysis

The surge of ultraprocessed foods—ready‑to‑eat items engineered for shelf‑stability and profit—has become a dominant feature of the American diet, now accounting for roughly 70 percent of daily calories. A growing body of research, including more than 100 observational studies and a controlled inpatient trial, links these products to higher rates of obesity, diabetes, and premature mortality. By embedding a call to limit “highly processed” foods in the 2025‑2030 Dietary Guidelines, the U.S. government is acknowledging this evidence base and moving beyond the traditional nutrient‑focused approach that has long guided policy.

The editorial by Marion Nestle underscores the political friction surrounding the new guidance. While the guidelines avoid the contested term “ultraprocessed,” they still signal a shift toward processing‑based recommendations, a move that the food industry has resisted due to profit concerns. Conflict‑of‑interest disclosures reveal that several authors of the supporting scientific reviews have financial ties to meat and dairy groups, fueling accusations of regulatory capture. Moreover, the lack of a universally accepted definition for ultraprocessed foods complicates enforcement, allowing manufacturers to reclassify products and dilute the policy impact.

Fed UP!—the campaign launched alongside the AJPH series—advocates a comprehensive policy toolkit: fiscal measures such as taxes on sugary or ultra‑processed items, subsidies for whole‑food alternatives, stricter marketing restrictions, and public procurement standards that prioritize minimally processed options. Internationally, Brazil’s 2015 dietary guidelines already embraced a minimally processed food paradigm, offering a model for integrating health, sustainability, and equity. If the United States adopts similar structural interventions, it could catalyze a market shift, incentivize reformulation, and ultimately reduce the disease burden associated with ultraprocessed consumption.
