The move is the latest voluntary effort by food manufacturers to heed calls from the Trump administration to remove synthetic dyes over concerns about potential health effects. In recent weeks, companies including Nestle, Kraft Heinz and General Mills said they would pull artificial colors from their foods, too.

“This is a Renaissance moment for health in America,” U.S. Food and Drug Administration Commissioner Marty Makary said at a news conference.

About 40 makers of ice cream and frozen dairy desserts said they would remove seven petroleum-based dyes from their products by 2028, according to Michael Dykes, president of the International Dairy Foods Association. The colors are Red 3, Red 40, Green 3, Blue 1, Blue 2, Yellow 5 and Yellow 6. The trade group wouldn’t identify the firms, although Turkey Hill Dairy chief executive Andy Jacobs joined the gathering.

The national focus on artificial food dyes is “a good step to take,” but officials should not ignore larger known contributors to chronic disease, including the added sugars and saturated fat commonly found in ice cream, said Deanna Hoelscher, a University of Texas nutrition expert.

“Just taking out or changing the food dye source is not necessarily going to make it a healthy option,” she said. “It still is a food that should be consumed in moderation.”

However, Makary also hinted that new federal dietary guidelines, expected later this year, would challenge established links between saturated fat and heart disease, ending what he called “a 70-year demonization of natural saturated fat.”

The average American eats about 4 gallons of ice cream a year, the IDFA said.

Health advocates have long called for the removal of artificial dyes from foods, citing mixed studies showing that they may cause some neurobehavioral problems, such as hyperactivity and attention problems, in some children. The Food and Drug Administration has maintained that approved dyes are safe and that “most children have no adverse effects” when consuming foods made with them.

Health Secretary Robert F. Kennedy Jr. has criticized the dyes and pressured manufacturers to remove them from foods. In their place, manufacturers should use dyes made from fruit juices, plant extracts and other sources, federal officials said.

The FDA has approved new natural color additives in recent months, including a new blue color made from the fruit of the gardenia announced Monday. Gardenia (genipin) blue is approved for use in sports drinks, candies and certain other products, the agency said.

Makary also sent a letter to food manufacturers on Monday that “encourages” them to speed up removal of the dye known as Red 3, which was banned in January. Food makers have until 2027 to remove the dye, which was found to cause cancer in laboratory rats, but not humans.

Some food companies have said they will stop using artificial dyes, but relying on voluntary action rather than regulatory requirements won’t guarantee compliance, said Thomas Galligan, a scientist with the Center for Science in the Public Interest, a consumer advocacy group.

“Talk is cheap,” Galligan said. “It’s easy for companies to make promises to look like they’re being compliant and generate goodwill among consumers and the Trump administration, but it remains to be seen if they will actually follow through.”
