The city of San Francisco has lodged a legal complaint against multiple ultra-processed food manufacturers, including Kraft, Mondelez, and Coca-Cola. The city claims these companies have knowingly endangered the health of Californians with their addictive and damaging products.

A Public Health Crisis

San Francisco’s City Attorney, David Chiu, filed the lawsuit in San Francisco Superior Court. The suit alleges that these corporations implemented strategies mirroring those of the tobacco industry, deliberately creating and promoting products to induce consumer addiction. The city accuses these companies of contravening California’s public nuisance and misleading marketing laws.

In a statement, Chiu commented, “These companies have manufactured a public health crisis, profited substantially, and must now be held accountable for the damage they’ve inflicted.”

The city argues that the surge in ultra-processed foods has precipitated a rise in obesity, cancer, and diabetes rates. Chiu’s office has underscored that heart disease and diabetes – both connected to ultra-processed foods – are among the principal causes of death in San Francisco, with low-income and minority communities experiencing higher diagnosis rates.

Industry Response

At the time of reporting, representatives for Mondelez, Coca-Cola, and Kraft Heinz had not yet provided comment on the lawsuit. However, Sarah Gallo, the Senior Vice President of Product Policy for the Consumer Brands Association, countered that there is currently no universally accepted scientific definition of ultra-processed foods. She suggested that categorizing foods as unhealthy based purely on their processed nature, or vilifying food by disregarding its complete nutrient content, can mislead consumers and exacerbate health disparities.

Implications and Precedence

The city aims to obtain restitution and civil penalties to alleviate its healthcare costs and is seeking a court order to prevent these corporations from engaging in misleading marketing and mandate changes in their practices.

While the classification of ultra-processed foods is still disputed, researchers typically refer to many packaged snack foods, sweets, and carbonated drinks made using processing methods, additives, and industrial ingredients, which primarily contain little whole foods.

The lawsuit is significant as it is the first instance of a municipality suing over allegations that food companies have knowingly advertised and sold harmful and addictive ultra-processed foods.

This lawsuit follows a similar case brought forward by a man from Philadelphia, who alleged that he was diagnosed with Type 2 diabetes and non-alcoholic fatty liver disease at the age of 16 due to his consumption of ultra-processed foods. However, this lawsuit was dismissed in August after a federal judge in Pennsylvania stated the plaintiff failed to link specific products to his health conditions.
