What once centered on whole foods prepared at home has given way to a food supply dominated by products engineered in factories rather than grown on local farms, or even backyards. These ultra-processed items now fill roughly 70 percent of grocery store shelves. San Francisco’s city attorney has decided enough is enough, filing what may be the nation’s first government lawsuit against the corporations behind these products.

The legal action names ten major manufacturers, including Coca-Cola, PepsiCo, and Kraft Heinz, accusing them of deceptive practices that have left cities and counties to foot the bill for resulting health consequences. This case could set a precedent for how communities hold food companies accountable for public health costs and the detriment they cause to overall health.

The Evolution of America’s Food Supply

Decades of food science research and marketing strategies have reshaped the food industry and have redefined what food is. Ultra-processed foods—those containing ingredients like emulsifiers, artificial colors and flavors, and preservatives—have become dietary staples for millions of families.

These products appeal to busy people and budget-conscious shoppers with their convenience and low prices. Children consume more than 60 percent of their daily calories from these foods, while adults aren’t far behind. The packaging often features health-washing words like “natural” or “whole grain,” creating an illusion of nutritional value that doesn’t match the ingredient list inside.

Research published in recent months has connected ultra-processed food consumption to serious health outcomes. Studies link these products to increased risks of type 2 diabetes, heart disease, certain cancers, cognitive decline, and depression. The evidence suggests that harm extends to every major organ system, creating a cascade of chronic conditions that burden healthcare systems nationwide.

The Lawsuit and Its Implications

San Francisco’s legal action, filed in California Superior Court, seeks damages for the costs local governments bear treating diseases linked to ultra-processed food consumption. City Attorney David Chiu argues the manufacturers have engaged in unfair and deceptive practices, violating state competition and public nuisance laws. The suit claims these companies knew their products caused harm but prioritized profits over public health.

The ten defendants represent some of the most recognized names in American food manufacturing. Their products range from sugary cereals and chips to items marketed as healthy alternatives like breads, granola bars, and frozen dinners that carry misleading health halos. Chiu points to marketing tactics borrowed from the tobacco industry playbook with colorful packaging, cartoon characters, and partnerships with toy manufacturers that specifically target children and low-income communities.

California has already taken steps to address ultra-processed foods in schools. The state recently passed legislation defining these products and creating a framework for removing them from school menus. Additional laws have banned certain food dyes and additives linked to behavioral issues in children. San Francisco itself prohibited fast-food restaurants from offering free toys with meals back in 2010.

The city attorney’s office brings a strong track record to this case. Previous victories against tobacco companies netted a $539 million settlement in 1998, while a case against lead paint manufacturers concluded after 19 years with a $21 million award. These successes show San Francisco’s willingness to pursue lengthy litigation against powerful corporations when public health is at stake.

Food industry representatives have pushed back against the lawsuit’s premise. The Consumer Brands Association, representing many named defendants, argues that no agreed-upon scientific definition of ultra-processed foods exists. They contend that classifying foods as unhealthy simply because they undergo processing misleads consumers and worsens health disparities. The trade group emphasizes that manufacturers follow FDA safety standards and increasingly offer products with reduced sugar, sodium, and synthetic additives.

One has to wonder why so many foods are legally allowed to be sold across the United States when they’re banned in other countries, but San Francisco is setting the precedent by saying enough is enough. Food should be fuel, and nobody should have to sacrifice health because they can’t afford it, they’re being misled with health-washing claims, or because they live in a food desert with no better alternatives. 

Final Thoughts

San Francisco’s decision to pursue food manufacturers in court signals a turning point in how communities view corporate responsibility for health outcomes. The costs of treating diet-related diseases have grown too large for local governments to absorb without questioning who should bear that burden.

This lawsuit also represents a reckoning with how food science and marketing have reshaped what Americans eat. For decades, corporations engineered products to maximize palatability and profits while obscuring nutritional realities through clever packaging and health claims. Whether courts ultimately side with San Francisco or the manufacturers, the case forces a long-overdue public conversation about who benefits from the current food system and who pays the price.
