Mars Wrigley Confectionery, the maker of M&M's and Skittles, is resisting efforts led by Health Secretary Robert F. Kennedy Jr. to remove synthetic dyes from its products. Despite ongoing initiatives by federal health officials under the Trump administration to phase out artificial food colorings, the candy industry continues to use these synthetic dyes. Mars Wrigley has publicly defended the use of artificial colorants, opposing the government's push for change.
