In the boardrooms of some of the world's largest food corporations, a familiar calculation has reportedly been made: it is cheaper to litigate than to reformulate. Between 2010 and 2025, ultra-processed food (UPF) companies filed 235 lawsuits against governments in Mexico, Colombia, Brazil, the United States and the United Kingdom — all of them targeting public health measures designed to reduce junk-food consumption. The figure was uncovered by a joint investigation involving The Guardian, the non-profit newsroom Lighthouse Reports, academic researchers, and media partners operating across four continents. The policies under legal attack are not obscure regulatory experiments.

They include front-of-pack warning labels, restrictions on advertising unhealthy products to children, and taxes on sugary and heavily processed foods — measures that health economists have linked to measurable reductions in diet-related disease. Publicly, the same corporations that filed these cases have insisted they support consumer choice and want to be "part of the solution." Tedros Adhanom Ghebreyesus, the WHO Director-General, described that position bluntly: "When harm and profit are tied to the same product, a familiar pattern of industry interference emerges: sowing doubt and obstructing regulation." The litigation record is, on its face, a poor one for the industry — roughly three-quarters of the resolved cases were won by governments.

Yet the headline win-rate obscures a more damaging mechanism. Even unsuccessful lawsuits forced health ministries to spend years, and significant public funds, defending evidence-based policy in court rather than implementing it. That delay has a measurable human cost: nearly one billion people are currently living with obesity worldwide, and unhealthy diets remain a primary driver of heart disease, type 2 diabetes and cancer. What the investigation ultimately reveals is a strategic asymmetry.
