Kellogg's has altered the recipe for its popular Rice Krispies cereal, a change that nutritionist Rhiannon Lambert calls a "disappointing missed opportunity" due to persistent issues with low fiber and high sugar content. The reformulation replaces puffed rice grains with rice flour and wheat, a move necessitated by global supply chain disruptions and grain availability, according to the company. This ingredient switch poses a potential risk for individuals with coeliac disease or gluten sensitivities, as the cereal now contains wheat.
A standard 30g serving of Rice Krispies contains 117 calories, 2.4g of sugar, and less than 0.5g of saturated fat. However, it offers minimal nutritional benefits, with only 2.1g of protein and less than a gram of fiber. Dietician Nichola Ludlam-Raine highlights that unlike whole-grain cereals such as Weetabix and Bran Flakes, Rice Krispies are not made from whole grains, which are rich in fiber, vitamins, and minerals essential for reducing the risk of bowel cancer and heart disease. Britons, on average, consume only 4% of the recommended daily fiber intake of 30g.
Despite these drawbacks, a bowl of Rice Krispies can provide a rapid energy boost, particularly beneficial before prolonged endurance exercise. Sports nutritionists recommend high-carbohydrate, low-fat, low-fiber, and ideally low-sugar snacks in the 30-60 minutes preceding intense workouts. The predominantly starch-based carbohydrate in processed rice is readily digestible, converting to glucose and providing energy without the digestive slowing effects of high fiber or protein.
Compared to other cereals, Rice Krispies' nutritional profile is similar to Cornflakes, which also offer little fiber and modest protein. Weetabix stands out as a highly nutritious option, with two biscuits providing significantly more fiber and protein. Shreddies offers a good amount of fiber and protein but contains more sugar than ideal. Special K is fortified with iron and folate but is also low in fiber and higher in sugar. Bitesized Shredded Wheat is praised for its simplicity, being made entirely from whole grain wheat with virtually no sugar or salt, though it lacks fortification. Frosties are considered less healthy than Rice Krispies due to their high sugar content and low fiber and protein. Cheerios fall in the middle, offering more sugar than Rice Krispies but also considerably more protein and fiber.
