Food Companies Being Sued Over Foods Designed to Be Hard to Stop Eating

The food on grocery store shelves has been changing for decades. More and more of what Americans eat comes not from farms but from factories — products made with dozens of ingredients engineered to be cheap to produce, slow to expire, and very hard to stop eating once you start.

Now those same companies are facing a wave of legal pressure. San Francisco’s city attorney filed a lawsuit against some of the biggest names in the American food industry, accusing them of knowingly designing their products to override the body’s natural signals and keep people eating more than they should. And in March 2026, thirty-two separate class action complaints were filed in courts across the country by consumers making similar claims.

What Are These Companies Being Accused Of?

The lawsuits draw a direct comparison to Big Tobacco. Just as cigarette companies are accused of hiding what they knew about addiction and health harm, the food lawsuits allege that major manufacturers:

• Hired scientists specifically to identify combinations of sugar, salt, fat, and chemicals that make it nearly impossible to stop eating
• Added emulsifiers, flavor enhancers, and other chemical additives designed to make the brain crave more
• Conducted internal research showing their products caused health problems — and buried the results
• Marketed these products to children and low-income families who had fewer healthy options available
• Spent decades lobbying against nutrition regulations that might have limited their products

The companies named in these lawsuits include Kraft Heinz, PepsiCo, Coca-Cola, General Mills, Nestlé, Mars, ConAgra, Mondelez, Kellogg’s, and Post.

What Health Conditions Are Linked to These Foods?

The lawsuits focus on conditions that researchers have increasingly connected to regular consumption of ultra-processed foods. These include:

• Type 2 diabetes — a condition that affects how the body processes blood sugar, often requiring lifelong management and medication
• Fatty liver disease (also called non-alcoholic fatty liver disease) — a buildup of fat in the liver that can lead to serious liver damage over time
• High blood pressure and related heart problems
• Obesity and related metabolic disorders

The lawsuits specifically allege that these conditions developed in children and adults who were never told about the risks — and who would have made different choices if they had known.

Who Is Suing and Where?

The city attorney of San Francisco, David Chiu, filed suit on behalf of the people of California. San Francisco is not the only government entity involved — other cities and states are watching closely, and more government lawsuits are expected.

In March 2026, thirty-two separate class action complaints were filed in federal courts, concentrated in New York and California. These cases were filed by individual consumers and families, not just government agencies. Legal experts say the volume of cases signals that courts are now treating these food health questions the same way they treated tobacco decades ago.

What Makes Ultra-Processed Food Different From Regular Food?

Not all processed food is the same. Cutting an apple into slices is processing. Canning tomatoes is processing. What the lawsuits focus on is a different category entirely — products that go far beyond basic preparation and into industrial manufacturing.

Ultra-processed foods typically contain long lists of ingredients that would not appear in a home kitchen: artificial flavors, chemical preservatives, emulsifiers like carrageenan, sweeteners, and color enhancers. The lawsuits argue these ingredients were not chosen randomly — they were specifically tested and selected to maximize how much people eat and how often they come back for more.

Do You Have a Claim?

These cases are still developing. No settlements have been reached yet, and the legal process for cases of this scale typically takes years. However, getting in early matters — filing deadlines apply, and documenting your situation now while details are fresh is important.

Situations worth speaking with an attorney about include:

• You or a family member regularly ate packaged snack foods, fast food, sodas, sugary cereals, or similar products for an extended period
• You or a family member was later diagnosed with Type 2 diabetes, fatty liver disease, high blood pressure, or other related conditions
• The diagnosis came at a relatively young age, or the condition worsened despite efforts to manage it
