Kellogg's has updated the recipe for its popular Rice Krispies cereal, replacing puffed rice grains with rice flour and wheat. This change, attributed to disruptions in global supply chains and grain availability, has raised concerns for individuals with coeliac disease and gluten sensitivities, as the cereal now contains wheat.
Nutritionists have expressed disappointment, noting that the reformulation did not significantly improve the cereal's nutritional profile. According to dietitian Rhiannon Lambert, the quantity of fiber remains low and sugar content is still high. A standard 30g serving contains 117 calories, 2.4g of sugar, and minimal fiber (less than 1g) and protein (2.1g).
Dietitian Nichola Ludlam-Raine highlighted that cereals made with wholegrains, such as Weetabix and Bran Flakes, offer more substantial nutritional benefits, including higher fiber content and essential vitamins and minerals. While Rice Krispies are fortified with vitamins D, iron, folate, B12, and niacin, their lack of wholegrains means they are not as nutrient-dense as other breakfast options.
Despite these concerns, there is a noted benefit to consuming Rice Krispies before intense exercise. Sports nutritionists recommend carbohydrate-rich snacks with low fat, fiber, and sugar for prolonged endurance activities. The readily digestible starch in Rice Krispies can provide a quick energy source, aligning with recommendations for a light, carbohydrate-focused pre-workout snack.
Comparing Rice Krispies to other popular cereals, dietitians found several alternatives to be more nutritionally sound. Cornflakes share a similar profile with low fiber and protein. Weetabix stands out for its high wholegrain content, fiber, and protein. Shreddies also offer a good amount of fiber and protein, though with higher sugar content than ideal. Special K is noted for its fortification with folate and iron but is lower in fiber and higher in sugar. Bitesized Shredded Wheat is praised for its simplicity, being made entirely of wholegrain wheat with virtually no sugar or salt. Frosties are considered less healthy due to their high sugar content and low fiber and protein. Cheerios fall in the middle, offering more fiber and protein than Rice Krispies but also containing more sugar.
