A recent global investigation by The Guardian has uncovered a striking pattern: when governments introduce policies to curb the harms of ultra‑processed foods (UPF), many of the world’s biggest food corporations respond not with collaboration, but with litigation.
Since 2010, at least 235 lawsuits have been filed across Mexico, Colombia, Brazil, the US and the UK, largely aimed at delaying or weakening public health measures designed to reduce UPF consumption.
The reporting, conducted with academics and Lighthouse Reports, reveals that three‑quarters of these lawsuits were brought by UPF manufacturers or their trade associations. Some companies even requested anonymity from the courts, underscoring the sensitivity of their legal strategies.
Experts interviewed by The Guardian draw a direct line between the tactics of UPF companies and those historically used by the tobacco industry. Marion Nestle, professor of nutrition at New York University, argues that food manufacturers “follow the tobacco industry playbook to the letter. When all else fails, sue”.
Years-long delays
Phillip Baker of the University of Sydney notes that while governments win most cases, the real impact lies in years‑long delays, regulatory “chilling effects,” and the sheer burden placed on public institutions forced to defend their policies in court.
Some legal battles add up to almost 600 years spent in court, slowing the rollout of front-of-pack warning labels, junk-food taxes, and marketing restrictions aimed at protecting children and reducing diet-related disease.
The Guardian’s reporting highlights the scale of the public health challenge. UPF consumption is rising globally and now accounts for up to half of the average diet in countries such as the UK, the US and Australia. Evidence reviewed by leading experts and published in The Lancet links high UPF intake to overeating, poor nutritional quality, and exposure to harmful additives and chemicals.
As fresh food is displaced by cheap, convenient UPF, governments have increasingly turned to regulatory tools—warning labels, marketing restrictions, and taxation—to curb consumption and protect public health.
A global barrier to health reform
The Guardian’s investigation makes one thing clear: litigation is becoming a central battleground in global food policy. Governments face several emerging challenges:
1. The Legal Arms Race
Corporations with vast financial resources can outspend public agencies, prolonging cases for years and draining public budgets. Even unsuccessful lawsuits can stall life‑saving policies.
2. Regulatory Paralysis
In countries like the UK, experts warn that the threat of legal action has contributed to “complete policy paralysis,” with officials “terrified” of being sued by food companies.
3. Global Coordination Gaps
Latin America has led the world in strong food‑environment policies, which is why Mexico, Colombia and Brazil account for most lawsuits filed. But without coordinated international standards, companies can target countries with weaker legal frameworks or exploit inconsistencies across borders.
4. Corporate Influence in Science and Policy
The Guardian previously revealed cases in which scientists advising governments on UPF policy had ties to major manufacturers, and in which lobbying campaigns successfully weakened public health guidance in the UK. Governments will need stronger safeguards against conflicts of interest.
5. The Rising Health Burden
As litigation slows policy adoption, UPF consumption continues to rise, contributing to obesity, type 2 diabetes, heart disease, mental ill health and other conditions. Delays today translate into higher healthcare costs tomorrow.
6. The Need for Political Courage
Experts interviewed by The Guardian argue that governments must be “bold” and resist intimidation. Delaying action due to fear of litigation “risks prolonging preventable harm,” which becomes harder and more expensive to address over time.
A new era in food policy
The Guardian’s investigation shows that the fight over ultra‑processed foods is no longer just about nutrition—it’s about legal power, political will, and governments’ ability to regulate industries whose products are deeply embedded in modern diets.
As UPF consumption continues to rise and public health costs mount, governments will need to prepare for a future where every major policy intervention may trigger a courtroom battle. That means strengthening legal capacity, insulating regulators from corporate influence, and building international alliances that make it harder for companies to challenge health measures country by country.
The Guardian’s reporting provides a crucial warning: without robust legal and political strategies, even the strongest public health policies risk being stalled before they ever reach the people they are meant to protect.
