General Mills Inc. is planning to engage federal officials over potential restrictions on food dyes that it uses in some of its cereals, as Robert F. Kennedy Jr., the nominee to run the Department of Health and Human Services, calls for them to be removed.

“Because this is always an evolving space, we work in close partnership with policymakers on this issue,” the company said in a statement. “We will engage with federal regulators as they consider any additional changes they may propose.”

Kennedy boosted attention on the use of dyes in the final weeks of the US presidential campaign as a high-profile supporter of Donald Trump, who then made him his choice to run HHS.

“The first thing I’d do isn’t going to cost you anything because I’m just gonna tell the cereal companies: Take all the dyes out of their food,” Kennedy said late last month.
