Health Secretary Robert F. Kennedy Jr. and FDA Commissioner Marty Makary said on Tuesday that the agency plans to remove synthetic food dyes from the U.S. food supply by revoking authorizations of some and working with industry to voluntarily remove others.

They cited concerns about a possible link between consumption of the dyes and health conditions like ADHD, obesity and diabetes, an area many scientists say requires more research.

The FDA said it is taking the following actions:

  1. Establishing a national standard and timeline for the food industry to transition from petrochemical-based dyes to natural alternatives.
  2. Initiating the process to revoke authorization for two synthetic food colorings—Citrus Red No. 2 and Orange B—within the coming months.
  3. Working with industry to eliminate six remaining synthetic dyes—FD&C Green No. 3, FD&C Red No. 40, FD&C Yellow No. 5, FD&C Yellow No. 6, FD&C Blue No. 1, and FD&C Blue No. 2—from the food supply by the end of next year.
  4. Authorizing four new natural color additives in the coming weeks, while also accelerating the review and approval of others.
  5. Partnering with the National Institutes of Health (NIH) to conduct comprehensive research on how food additives impact children’s health and development.
  6. Requesting food companies to remove FD&C Red No. 3 sooner than the 2027-2028 deadline previously required.

Removing food dyes from the food supply will largely be left to the food companies, however, as many of these steps are voluntary.
