The Claim

Ultra-processed foods account for the majority of calories consumed by American adults as of March 2026.

Verified by Lenz ·

The Short Version

The claim is well-supported. A 2025 CDC report found American adults consumed 53% of their calories from ultra-processed foods during 2021–2023, and peer-reviewed research consistently places the figure above 50%. However, the most recent primary data doesn't extend to March 2026 specifically — it's an extrapolation from a 2021–2023 survey window. No evidence suggests the trend has reversed below the majority threshold, but the "as of March 2026" framing implies more current measurement than exists.

Caveats

  • The most recent nationally representative data (CDC) covers August 2021–August 2023, not March 2026 — the claim's timeframe is an extrapolation, not a direct measurement.
  • There is meaningful variation by income: higher-income adults consume a lower share of UPF calories, so the 'majority' threshold may not apply uniformly across all subgroups.
  • There is no universally agreed-upon definition of 'ultra-processed foods' — the 53% figure relies on the NOVA classification system, and the 2025–2030 Dietary Guidelines deliberately avoided the term.
