Last month, the Food and Drug Administration announced it is banning Red No. 3, a food dye additive in processed foods like sodas, sweets and snacks. Recently, it and other dyes were linked to negative behavioral issues in children, and decades ago, high levels of Red No. 3 were linked to cancer in rats. This episode, NPR science podcast Short Wave explains what we know about Red No. 3's harmful health effects and the other dyes that may replace it.

  • President Trump is back in Washington pursuing major policy changes on his own terms.

  • We know from the past that means challenging precedent, busting norms and pushing against the status quo.

  • NPR is covering it all with Trump's Terms, a podcast where we curate stories about the 47th president with a focus on how he is upending the way Washington works.

  • Listen to Trump's Terms from npr.

  • You're listening to Life Kit from npr.

  • Hey, everybody, it's Marielle.

  • When you see desserts or candy or medications that are bright cherry red, they often contain some sort of synthetic food dye.

  • One of those dyes, red dye number three, has been found to cause cancer in rats, and the Food and Drug Administration is now banning it in food and ingested drugs.

  • Our friends at NPR's Science Podcast shortwave dove into the science behind the ban and talked about other food dyes, too, like Red 40.

  • So we've got that episode for you today.

  • I'll turn it over to Shortwave co host Emily Kwong.

  • Hey, short wavers.

  • Emily Kwong here with the lovely Maria Godoy, senior editor and correspondent with the NPR Science Desk.

  • Hey, Maria.

  • Hey, Emily.

  • You are here to walk me through an announcement from the Food and Drug Administration.

  • That's like a pretty big deal.

  • Yeah.

  • So they announced that they're banning the food dye red number three, or in FDA terms, that's revoking authorization.

  • Very official.
