A blockbuster lawsuit accuses America’s food giants of engineering addiction, deceiving consumers, and driving a national health crisis — a legal showdown with global implications, including for India.
By P. SESH KUMAR
New Delhi, December 10, 2025 — San Francisco has hurled a legal thunderbolt at America’s biggest food companies, accusing them of orchestrating a public-health catastrophe through the creation, promotion and normalization of ultra-processed foods (UPFs).
The lawsuit names ten corporate giants-from Kraft Heinz and Coca-Cola to Kellogg, Nestlé and Mars-and charges them with engineering addictive, nutrient-poor products; aggressively marketing them to children and vulnerable communities; and burying evidence of long-term harm linked to obesity, diabetes, heart disease, fatty-liver disease and even cancer.
The broad contours of the viral narrative are accurate: this is the first major government lawsuit directly targeting UPFs as a class, built on legal theories lifted straight from Big Tobacco and opioid litigation. What the online version misses is the nuance: the City bases its case on public-nuisance and unfair-competition law rather than classic product-liability doctrines, and the science on “addictiveness” and the definition of “ultra-processed” remains contested.
Still, the lawsuit sits atop a fast-rising mountain of epidemiological evidence linking heavy UPF consumption to chronic disease.
San Francisco’s case begins with a blunt accusation: the defendants knowingly flooded the American diet with engineered, hyper-palatable products that distort appetite, override satiety and encourage chronic over-consumption.

The City’s complaint mirrors the viral summary closely-yes, it explicitly claims these companies designed foods for “maximal over-consumption,” knowingly targeted children and low-income neighbourhoods, wrapped unhealthy products in misleading “health halo” messaging, and concealed or downplayed the scientific consensus linking UPFs to metabolic disorders.
This is not rhetorical flourish; it is the City’s own language. The list of defendants matches the real complaint, and the comparison to Big Tobacco is not metaphorical-it is the City’s chosen narrative strategy.
The accuracy of the viral content weakens only when it strays into legal terminology. The lawsuit does allege deception, misrepresentation and omission, but it is not structured as a conventional negligence or product-liability case.
Instead, it leans on California’s Unfair Competition Law and the public-nuisance doctrine-legal routes that give the City broader flexibility to frame UPFs as a societal harm rather than a personal dietary choice.
The claim of “failure to warn” is more an inference than a formal pleading. Even so, the thrust remains: San Francisco argues that a small group of firms engineered a food environment that systematically undermines public health, particularly in communities already facing structural disadvantage.
The science, too, is not invented for litigation. A series of umbrella reviews published between 2023 and 2025 have connected high UPF intake to over 30 adverse outcomes, including obesity, hypertension, depression, cardiovascular disease and multiple cancers. The causal chain is complex and not as clear-cut as tobacco, but the chorus of evidence is getting louder.
The City is betting that courts will view the combination of science, corporate conduct, marketing patterns and public-health costs as enough to justify intervention. The defendants will counter that observational studies cannot prove causation, confounding variables abound, and “ultra-processed” is a contested academic label rather than a statutory category.

The legal strategy borrows heavily from past public-health litigation successes. Tobacco companies fell not because cigarettes were suddenly discovered to be harmful, but because internal documents revealed deliberate concealment of risks, manipulation of nicotine levels, and strategic targeting of youth.
Opioid manufacturers collapsed under evidence showing they downplayed addictiveness, coached doctors to overprescribe, and seeded narratives of “safe chronic opioid use” they privately knew were false. San Francisco is attempting a similar storyline: industrial food companies allegedly understood how highly processed formulations drive overconsumption, recognised their products’ role in chronic disease, and chose to deepen-not mitigate-those risks because the profits were enormous.
Yet the terrain here is more treacherous. Cigarettes and opioids have no nutritional upside; ultra-processed foods occupy a spectrum ranging from sugary drinks to fortified cereals. That ambiguity gives industry both scientific and legal room to manoeuvre. They will argue that the City is criminalizing “processing” rather than harmful ingredients; that the FDA-not local courts-is the proper regulator; and that any government-mandated warnings or advertising restrictions violate First Amendment protections.
San Francisco’s attempt to require soda-ad warnings was struck down by the Ninth Circuit on exactly these grounds. If this new case reaches the same appellate court, broad structural remedies may be trimmed sharply.
Still, litigation is not purely about winning in court.
Even reaching discovery would be a seismic victory for public-health advocates. Internal documents could expose decades of research on consumer behaviour, satiety manipulation, sugar-fat-salt optimisation, child-targeted marketing and corporate assessments of UPF-related health risks.
Just as the tobacco “document vaults” reshaped global regulation, a similar cache from Big Food could permanently change the conversation.
The implications reach far beyond San Francisco. Regulators like FDA, FTC and USDA are under intensifying pressure to modernise a regulatory system still stuck in a nutrient-labelling era while disease patterns are driven by whole-diet dynamics. Legislators in other states may pursue similar suits.
Corporate reputation risk may force reform even without legal defeat-changes in product formulation, stricter marketing rules, improved transparency and self-regulation may emerge simply to avoid being the next defendant.
This legal earthquake also raises a bracing question for India, where obesity, diabetes, hypertension and fatty-liver disease are rising faster than almost anywhere else in the world.
If a San Francisco-style lawsuit were to be imagined in New Delhi or Mumbai, courts would confront a very different doctrinal terrain—one where public-interest litigation appears far more elastic, consumer law far sharper, and constitutional courts more willing to intervene in matters of public health.
Indian jurisprudence offers powerful tools: the Consumer Protection Act’s wide definition of “unfair trade practices,” the Food Safety and Standards Act’s stringent rules on misbranding and misleading advertisements, and the Supreme Court’s interpretation of the right to health as part of Article 21’s guarantee of life and dignity.
Indian courts have repeatedly scrutinized misleading ads, junk-food sales near schools, unsafe formulations, and deceptive health claims-often with fewer evidentiary hurdles than American courts. Whether or not a sweeping UPF lawsuit (class action suits are a novelty) emerges in India, the signal is unmistakable: silent reformulation will no longer shield companies, consumers are becoming more aware, regulators more assertive, and the health crisis more visible.
For Indian food corporations, the lesson is to reform before being forced to; for consumers, it is a reminder that the consequences of the UPF economy are no longer theoretical-they are sitting in outpatient clinics every day.
Back in the U.S., courts will tread cautiously. Trial courts may allow the case to proceed narrowly-especially on deceptive-marketing claims-but appellate courts will likely prune anything resembling judicial food policy.
The strongest legally resilient outcomes are targeted findings that specific ads or omissions misled consumers or that certain child-directed campaigns crossed the line. That is the sort of case an appellate court can affirm without rewriting the food code.
The broader public-policy lesson is unavoidable: America’s (and increasingly India’s) diet-related disease burden is now so vast, and the food environment so shaped by industrial strategy, that litigation has become a tool of last resort.
Whether this lawsuit succeeds or fails, it already signals that the era of unquestioned corporate freedom in food engineering and marketing is ending. Governments, courts, corporations and consumers must confront the uncomfortable truth that chronic disease is not merely a matter of personal responsibility but the predictable outcome of a system optimized for profit, not health.
The way forward lies in a mix of litigation, regulation, transparent labelling, stricter marketing rules, consumer education, fiscal incentives for healthier products and investment in minimally processed alternatives-not in expecting one lawsuit to fix an entire food ecosystem.
But San Francisco has cracked open the door, and it will not close again soon.
