Kellogg’s swaps whole rice for corn flour in UK Rice Krispies amid climate challenges

Recipe change and consumer reaction

Kellogg’s has replaced whole rice grains with corn flour and rice flour in its UK Rice Krispies and Coco Pops cereals, adding wheat gluten to the recipe. The change comes as the company faces disrupted grain supplies due to "changing weather conditions," particularly in Spain, where extreme weather has reduced the availability of the rice varieties traditionally used in the cereals.

Consumer response has been overwhelmingly negative, with complaints about the altered taste, texture, and a quieter "snap, crackle and pop" sound. The sound has been a hallmark of Rice Krispies’ branding since the 1950s, and some parents report their children are refusing to eat the reformulated version. TikTok user Lauren, a longtime consumer, described noticing an immediate difference after years of daily consumption.

Kellogg’s reasoning and nutritional claims

Kellogg’s stated that the reformulation was necessary to "maintain consistent quality" amid rising ingredient costs and crop shortages linked to extreme weather. The company emphasized that the new recipes meet UK food standards for fat, salt, and sugar, and retain the same nutritional benefits, including fibre, Vitamin D, and iron. Packaging will now include a "contains wheat gluten" warning, replacing the previous "may contain gluten" label due to cross-contamination risks.

The company insisted that the iconic sound is "still there," though quieter and less instantaneous. A Kellogg’s spokesperson said: "We appreciate that even small changes to a much-loved product can feel noticeable and that's why we have approached this with a lot of care and consideration."

Ownership split and regional differences

In 2023, Kellogg’s split into two separate companies: Kellanova, which includes global snack and cereal brands like Pringles and Pop-Tarts and is now owned by Mars, and WK Kellogg’s, the North American cereal business, which was acquired by Ferrero. The recipe changes affect only the UK market, as Rice Krispies products in the US and Canada remain under WK Kellogg’s and will continue to use whole rice grains.

The split reflects broader industry shifts, with global brands adapting to regional supply chain challenges and ownership structures. Ferrero’s acquisition of WK Kellogg’s and Mars’ takeover of Kellanova highlight how legacy brands are being reshaped by new corporate strategies.

Climate impact on food production

Kellogg’s attributed the recipe change to disruptions in grain supplies caused by extreme weather, particularly the El Niño phenomenon, which has affected crop production in South East Asia—a region responsible for over a quarter of the world’s rice output. Rice harvests in key producing countries have been hit by droughts and heatwaves, driving up prices and reducing availability.

The World Meteorological Agency expects El Niño to persist until at least 2027, suggesting that climate-related supply chain disruptions could become more frequent. For food manufacturers, this raises questions about long-term ingredient sourcing and the trade-offs between maintaining product consistency and adapting to environmental pressures.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

For founders and operators in the food industry, Kellogg’s recipe change underscores the growing impact of climate change on supply chains and consumer expectations. The backlash highlights how deeply iconic product traits—even sensory ones like sound—are tied to brand loyalty. Companies facing similar supply pressures may need to weigh the risks of reformulation against the potential loss of consumer trust, particularly for products with decades of brand equity.

The split between Kellanova and WK Kellogg’s also signals a trend of legacy brands adapting to regional challenges through structural changes. As climate patterns evolve, flexibility in sourcing and production may become a competitive advantage, but it requires careful communication to avoid alienating loyal customers.
