Case overview
In January 2026, plaintiff Shastin Jenkins filed a federal complaint in the Eastern District of Louisiana against Kraft Heinz, Mondelez, Coca-Cola, PepsiCo, General Mills, and Nestlé, alleging ultra-processed foods caused her type 2 diabetes. This follows the December 2024 Pennsylvania state court filing by teenager Bryce Martinez against similar defendants, which Judge Mia R. Perez dismissed in August 2025 for lack of specific causation allegations while noting the court was "deeply concerned" about UPF marketing practices. No MDL has been established; litigation remains nascent with parallel state and federal filings.
Causation Theory
Plaintiffs allege ultra-processed foods are engineered with precise combinations of sugar, salt, fats, and chemical additives to stimulate brain reward pathways and suppress satiety cues, creating compulsive consumption patterns. The theory draws on historical ties: Philip Morris and R.J. Reynolds acquired major food brands in the 1980s and allegedly repurposed nicotine addiction research to formulate hyper-palatable products. Scientific support includes a 2025 NIH study finding UPFs may be less satiating than unprocessed alternatives, and epidemiological research linking rising UPF consumption to increased early-onset colorectal cancer and type 2 diabetes in young males.
Litigation status
No MDL exists. The bellwether case Martinez v. Kraft Heinz Co., No. 25-377 (E.D. Pa.), was dismissed on August 25, 2025 by Judge Mia R. Perez for failure to plead specific causation and identify particular products consumed; plaintiff filed motion for leave to amend September 22, 2025. California enacted AB 1264 on October 8, 2025, providing first statutory definition of 'ultra-processed foods of concern' and banning certain UPFs from school meals.

Geographic exposure
Approximately 57% of daily caloric intake nationally; 58% in U.S. per BMJ 2025 umbrella review. No MDL established. Single federal dismissal in E.D. Pa. No active class certification. California statutory framework creates most favorable current jurisdiction for new filings.
Eastern District of Pennsylvania hosted first-of-its-kind UPF litigation: Martinez v. Kraft Heinz Co., No. 25-377, 2025 U.S. Dist. LEXIS 164054 (E.D. Pa. Aug. 25, 2025). Plaintiff Bryce Martinez, 19-year-old Philadelphia resident, alleged UPF addiction science and predatory marketing caused type 2 diabetes and liver disease. Court dismissed at pleadings stage for failure to allege specific causation and identify specific products consumed. Case filed December 2024 against Nestle, Heinz, Coca-Cola. No MDL established.
AB 1264 enacted October 8, 2025, providing first U.S. legal definition of 'ultra-processed foods of concern' and banning certain UPFs from school meals. Definition covers foods with thickeners, flavoring agents and enhancers. Creates regulatory framework for state-level enforcement and potential private litigation under California consumer protection statutes. Statute of limitations for UPF-related claims under state law: 2-4 years depending on cause of action.
UPF accounts for 57% of total daily calories consumed by American adults per 2017 data cited in BMJ umbrella review. High-income country range: 42% (Australia) to 58% (U.S.). National exposure concentration creates potential for class action certification where specific product identification and causation theories can survive pleadings.
BMC Public Health umbrella review (January 2026) identifies UPF as dominant in 'out-of-home sector' with most fast-food outlet food classified UPF. Populations dependent on UPF for affordability, practicality, safety and availability face elevated exposure. Emergency-dependent populations (natural disasters, remote areas) show concentrated reliance due to shelf-life and minimal preparation requirements.
AB 1264 ban on certain UPFs in school meals effective October 2025. Creates immediate compliance obligation for California school districts and potential exposure for manufacturers supplying non-compliant products. Pre-litigation regulatory violation status may support negligence per se theories in pending California filings.
