Kellogg said last August that it would remove synthetic dyes from its cereals by the end of 2027. In 2024, dozens of people rallied outside Kellogg's headquarters and delivered petitions with 400,000 signatures asking the company to remove artificial dyes and BHT. That pressure has grown under President Donald Trump's health secretary, Robert F. Kennedy Jr., who has urged food companies to phase out petroleum-based artificial dyes. Earlier this year, Target said it would stop selling cereals that contain artificial colors by the end of May. Walmart has also said it will remove artificial colors from its store brands by January 2027.
