Walmart said Wednesday that it plans to remove synthetic food dyes and 30 other ingredients, including some preservatives, artificial sweeteners and fat substitutes, from its store brands sold in the United States by January 2027. Walmart said its goal would affect about 1,000 products, including salty snacks, baked goods, power drinks, salad dressings and frosting. AdvertisementIn recent months, major food companies such as Kraft Heinz, Nestle and Conagra Brands have pledged to eliminate petroleum-based synthetic dyes in coming years. Those include synthetic dyes, titanium dioxide, azodicarbonamide, propylparaben, potassium bromate and phthalates, a chemical used to make plastic flexible. But some of the 11 artificial food dyes detailed by Walmart were already banned, proposed to be banned or haven’t been used for years, including Red No.
