Overview of RFK Jr. and the chocolate factory

This episode of Today, Explained examines Robert F. Kennedy Jr.’s “Make America Healthy Again” (MAHA) push to pressure food companies into removing artificial dyes and other ultra-processed ingredients. Through the example of the blue M&M, the episode shows how difficult it is for big food brands to reformulate products at scale, even when they agree with the broader health messaging. The takeaway: RFK Jr. has succeeded in changing the conversation, but the actual policy and product changes remain limited, voluntary, and uneven.

The Blue M&M as a case study

Why artificial dyes are in RFK Jr.’s crosshairs

  • RFK Jr. has repeatedly attacked petroleum-based food dyes, including the blue dye used in M&Ms.
  • He argues these additives are harmful, especially for children, and links them to:
    • hyperactivity
    • neurological issues
    • cancer risk
  • The episode notes that regulators have long considered these dyes safe for most people when used properly, though some children may be more sensitive.

What Mars tried to do

  • Reporter Jesse Newman visited a Mars factory in Topeka, Kansas to see how M&Ms are made.
  • Mars attempted to replace artificial blue dye with a natural alternative: spirulina (an algae-based ingredient).
  • That swap created major manufacturing problems:
    • spirulina arrives as a powder, unlike the liquid artificial dye
    • the mixture became thicker
    • it clogged pipes and coated machinery
    • it raised food safety concerns, including mold risk
  • Mars said the change would require retrofitting about 300 types of machinery and cost millions of dollars.

The result

  • Mars did not eliminate artificial dyes across the board.
  • Instead, it introduced a limited naturally dyed version of some products online.
  • The episode emphasizes that the classic artificially dyed M&Ms are still available in stores.
  • Bottom line: the “healthier” version is more of an option than a replacement.

What MAHA wants the grocery store to look like

RFK Jr.’s ideal grocery store would look much more like a perimeter-only, whole-foods market:

  • more produce
  • more meat
  • more whole-fat dairy
  • more butter and beef tallow
  • far fewer packaged, ultra-processed foods

The show frames this as part of a broader anti-ultra-processed-food movement, not just a dye issue.

What has actually changed in the food industry

Visible changes

  • Some companies have begun reformulating products, especially around colors and additives.
  • Examples mentioned:
    • General Mills removing artificial dyes from cereals
    • Trix becoming a more muted, dye-free version
    • Kellogg working on similar changes for Froot Loops
  • There’s also been a surge in “protein” branding across packaged foods, though that trend began before RFK Jr.

What hasn’t changed much

  • Many of the changes are voluntary, not required by law.
  • There is no strong regulatory mandate forcing broad reformulation.
  • Companies can reverse course if consumer demand shifts or political pressure fades.

How RFK Jr. is applying pressure

The episode stresses that RFK Jr. has used:

  • social media
  • public speeches
  • name-and-shame tactics
  • the visibility of his HHS role

He has called out brands like:

  • Froot Loops
  • Twinkies

But the pressure is mostly rhetorical. The administration has not backed it up with many binding rules.

Why the food industry is cautious

Food companies are open to change, but only if they can compete on a level playing field.

Their concerns

  • If one company reformulates and competitors do not, the first company may lose sales.
  • Healthier ingredients often cost more.
  • Consumers are already squeezed by high grocery prices.
  • Companies want government standards, not just voluntary pressure, so everyone follows the same rules.

What is stalling progress

The episode says a lot of RFK Jr.’s agenda has slowed or stalled because of:

  • affordability concerns
  • potential consumer backlash
  • legal risks
  • trade issues
  • White House reluctance to raise grocery prices before the midterms

One example: the government has been working on defining ultra-processed foods, but that work has been held up.

Main takeaway

The episode’s core argument is that RFK Jr. has helped make food reform a major cultural issue, but real structural change is still modest.

Bottom line

  • He has changed the conversation.
  • He has pressured companies into some reformulations.
  • But most of the changes are incremental, voluntary, and expensive.
  • And on the biggest issue—ultra-processed food and chronic disease—the U.S. still has a long way to go.
