A number of companies have committed to removing artificial dyes from their food and drink products since federal officials banned some of the dyes and said they would work with firms to remove others.
About 20 percent of packaged foods and drinks contain synthetic colors, according to a study published in the Journal of the Academy of Nutrition and Dietetics in June. Nine dyes were cleared by regulators, but three were recently banned. Regulators said they would be working with companies to phase out the remaining six.
