Dozens of companies that make ice cream and frozen dairy desserts announced on Monday that they would remove artificial food dyes from their products by 2028, marking yet another voluntary move away from such food coloring within the food industry. It comes in response to a mission set forth by Health and Human Services Secretary Robert F. Kennedy Jr. to remove the artificial additives. In April, Food and Drug Administration Commissioner Marty Makary said the agency would move to eliminate several synthetic dyes by the end of next year. That includes Green 3, Red 40, Yellow 5, Yellow 6, Blue 1, and Blue 2. Red 3 was set to be banned in food by 2027 because it caused cancer in laboratory rats; the FDA called for that deadline to move up. Artificial dyes are used widely in U.S. foods. In Canada and in Europe " where synthetic colors are required to carry warning labels " manufacturers mostly use natural substitutes. Several states, including California and West Virginia, have passed laws restricting the use of artificial colors in foods. Health advocates have long called for the removal of artificial dyes from foods, citing mixed studies indicating they can cause neurobehavioral problems, including hyperactivity and attention issues, in some children. The FDA has maintained that the approved dyes are safe and that "the totality of scientific evidence shows that most children have no adverse effects when consuming foods containing color additives."
