Dozens of protesters gathered outside WK Kellogg Co.’s Michigan headquarters, demanding the company remove artificial dyes from its cereals sold in the US. The protest, supported by petitions with over 400,000 signatures, called for the elimination of chemical additives like food dyes and BHT from products such as Froot Loops and Apple Jacks. Despite a promise nearly a decade ago to remove artificial colors, Kellogg continues to use them in the US while using natural dyes in international markets like Canada. Activists, led by food advocate Vani Hari, pointed to studies suggesting artificial dyes can contribute to behavioral issues in children. Kellogg defended its products, stating that over 85% of its cereal sales are from items without artificial colors and that all ingredients meet federal regulations. The company noted that US consumers show less demand for natural alternatives compared to other countries. California’s recent ban on several food dyes in public schools may push Kellogg to reconsider its stance. Four of the dyes now banned in the state are still used in Froot Loops.
