Walmart is the latest company to pledge to remove artificial dyes from its food products following the U.S. Food and Drug Administration’s (FDA’s) April announcement urging industry to cease the use of synthetic colorants, in line with U.S. Health Secretary Robert F. Kennedy Jr.'s (RFK Jr.'s) "Make America Healthy Again" (MAHA) agenda.

Some states—including California, Louisiana, and others—have also enacted their own bans on certain food dyes and additives, putting pressure on industry to reformulate their products.

Additional companies that have pledged to end the use of synthetic food colorants include, but are not limited to, the Campbell’s Company, Conagra Brands, Nestlé USA, General Mills, and The Kraft Heinz Company.
