Do we like Kellogg's?
Cereal and snack brand, now split: WK Kellogg Co (cereal, Michigan) and Kellanova (snacks, Pringles, Cheez-It, Pop-Tarts).
Our score: 4 out of 10. Familiar brands with a track record of sugar-health-claim suits and slow dye phase-outs. Not an obvious one to back with our money.
Kellogg's is no longer one company. The cereal side became WK Kellogg Co, and the snacks side became Kellanova (Pringles, Cheez-It, Pop-Tarts). Both have since been sold: Ferrero, the Nutella maker, agreed to buy WK Kellogg for about $3.1 billion, and Mars bought Kellanova.
The big legal drama was a US class action accusing Kellogg of deceptively marketing sugary cereals and snack bars as healthy. It agreed to a settlement of about $20 million in 2019, later revised to $13 million. It also agreed to change some label claims, and it didn't admit wrongdoing.
In 2025 the Texas attorney general opened an investigation into WK Kellogg for calling cereals like Froot Loops healthy while some contained petroleum-based dyes. The company then signed an agreement to remove the dyes by end of 2027. It said its foods are safe and comply with FDA rules. It had first pledged to drop artificial colours back in 2015.
Our score is a middling 4. We found no major scandals on workers or the environment in these searches. But the health-claim history and the repeatedly delayed dye pledge don't earn much trust. The brand's new owners will decide what happens next.
