There has been little voluntary movement by companies to eliminate artificial food dyes, prompting Consumer Reports’ action.

A year after Health and Human Services Secretary Robert F. Kennedy Jr. encouraged food companies to voluntarily phase out synthetic dyes, little action has been taken.

According to Consumer Reports, promises from major companies such as Coca-Cola, Mondelez and Unilever have not been realized. The non-profit group supported state legislation in states such as New York that would require food companies to disclose public information about food chemicals, including dyes.
