California's bold move to ban harmful ultraprocessed foods in schools by 2029

A new bill in California aims to set the first legal definition of ultraprocessed foods in the US. If signed into law, it would ban the most harmful versions from public schools by 2029. The proposal now sits with Governor Gavin Newsom, who has until mid-October to decide its fate. Republican Assemblymember James Gallagher co-authored the bill, which targets foods linked to serious health risks. Research connects ultraprocessed items—often high in salt, sugar, and unhealthy fats—to obesity, diabetes, heart disease, and mental health issues. Over half of all calories consumed by Americans fall into this category, according to CDC figures.

The bill doesn’t ban all ultraprocessed foods outright. Instead, it directs the California Department of Public Health to pinpoint the most concerning products by 2029. Factors like scientific evidence of harm and bans in other regions will guide the selection. Schools in the state serve nearly a billion meals annually, making the policy’s impact potentially widespread.

Supporters believe the law could push manufacturers to reformulate their products. The goal is to reduce children’s exposure to foods with little nutritional value while still allowing safer options to remain available. Governor Newsom has 30 days from September 12 to sign or veto the measure. If approved, California would become the first state to legally define and restrict ultraprocessed foods in schools. The changes would roll out gradually, with full implementation expected by the end of the decade.
