Landmark San Francisco Lawsuit Against Ultra-Processed Food Companies

On December 2, 2025, the City of San Francisco filed a historic lawsuit in San Francisco Superior Court against ten of the largest ultra-processed food manufacturers in the United States — including Kraft Heinz, The Coca-Cola Company, PepsiCo, Nestlé USA, General Mills, Mars, Kellogg, Mondelez, Post, and Conagra. The lawsuit alleges that these companies engineered and marketed highly processed foods with addictive qualities and limited nutritional value, contributing to chronic health conditions such as diabetes, obesity, and heart disease. San Francisco’s complaint argues that these corporate practices violate California’s Unfair Competition Law and public nuisance statutes, and asks the court to require changes to marketing practices and to impose penalties to help offset public health costs. The case has been widely described as the first-of-its-kind government action targeting ultra-processed food makers, sparking national attention on the health impacts of heavily processed foods and corporate accountability.

Research & Evidence for “Ultra-Processed Food in Fast Food Meals”

✅ 1. NOVA Food Classification

This is the standard scientific system for categorizing food by level of processing.
It is widely used in nutrition research.

Citation to use:

We reference the NOVA food classification system, which defines ultra-processed foods as industrial formulations with little whole food content and multiple additives for texture, flavor, and shelf life.

🔗 More info (public source):
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7399969/
(Key paper explaining NOVA and ultra-processed foods)

✅ 2. Fast Food Meals Are Predominantly Ultra-Processed

Multiple studies have shown that most calories in fast-food meals come from ultra-processed foods.

Citation to use:

Studies indicate that typical fast-food meals derive the large majority of their calories from ultra-processed ingredients, with only a small fraction coming from minimally processed sources.

🔗 Example research:
https://academic.oup.com/ajcn/article/105/4/975/4569658
(This paper and similar ones document fast food and ultra-processing)

✅ 3. Ultra-Processed Foods and Health Outcomes

This supports the idea that what’s in these meals — additives, industrial oils, sugars — affects metabolism and hunger.

Citation to use:

Consumption of ultra-processed foods has been linked in clinical research to patterns of appetite dysregulation, blood glucose instability, and increased caloric intake compared with unprocessed diets.

🔗 Key study:

(This randomized trial showed that ultra-processed diets increased calories and weight compared with whole-food diets)
