The In-N-Out burger chain has removed artificial coloring from its strawberry shakes and Signature Pink Lemonade, aligning with growing scrutiny of synthetic food dyes.
The move comes less than a month after the Food and Drug Administration urged food makers to voluntarily phase out petroleum-based artificial colors.
Company spokeswoman Patty Peña confirmed the changes, stating, “We’re also in the process of transitioning to an upgraded ketchup, which is made with real sugar instead of high fructose corn syrup,” reported Mercury News.
In-N-Out described the updates as “part of our ongoing commitment to providing our Customers with the highest-quality ingredients.”
The chain did not clarify whether other products still contain artificial dyes.
The announcement follows an April 22 FDA news conference at which Commissioner Marty Makary outlined plans to eliminate synthetic dyes by the end of 2026, primarily through voluntary industry efforts. Health Secretary Robert F. Kennedy Jr., present at the event, noted he had heard from food manufacturers but had no formal agreements.
The FDA plans to set standards and timelines for switching to natural alternatives, revoke authorization for unused dyes, and remove remaining synthetic dyes from the market.
Health advocates have long criticized artificial dyes, citing studies suggesting links to neurobehavioral issues like hyperactivity in some children. The FDA maintains that approved dyes are safe, stating, “The totality of scientific evidence shows that most children have no adverse effects when consuming foods containing color additives.”
Of the 36 allowed food color additives, eight are synthetic. In January, the FDA banned Red 3, used in candies and cakes, by 2027 after it caused cancer in lab rats.
