Kellogg’s has changed the recipe for the three products in its cereal and milk bar range to cut the sugar levels.

Coco Pops Bars have been reduced by 24% and Frosties and Rice Krispies Bars by 19%.

As part of the recipe change the cereal and snacks company has also added Vitamin D and extra fibre.

Alexa Hoyland, senior UK nutrition manager, said: “This reformulation is part of Kellogg’s commitment to giving people more of what they want and need, like fibre and added vitamins and minerals and less of what they don’t, like salt and sugar.

“We know parents want to give their children tasty snacks that are better nutritionally. That’s why we are reducing the sugar and increasing the fibre whilst keeping the great taste of these bars. We also want to provide opportunities for parents to give their children the vital nutrient, vitamin D, which we know children are not getting enough of.”
