Every Kellogg's cereal sold in the UK broken down by portion size and milk type, checked against NHS daily free sugar limits for children aged 4 to 17.
Kellogg's is the UK's most recognisable breakfast cereal brand. The products are familiar, widely available and eaten by millions of children every morning. What is less visible is how significantly the nutritional picture varies across the range.
A 30g bowl of Corn Flakes contains 2.4g of free sugar. The same size bowl of Frosties contains 11.1g. Both are Kellogg's cereals. Both sit on the same supermarket shelf. The difference in free sugar is almost fivefold.
All Kellogg's cereals start with a grain base - corn, rice, wheat or oats, which is refined, mixed with sugar and other ingredients, then shaped and toasted during manufacturing. The refining process removes the bran and germ layers from the grain, which is where most of the natural fibre sits. This is why most Kellogg's cereals are low in fibre despite being marketed as part of a healthy breakfast.
Every cereal in the range is fortified with the same added vitamins and minerals during manufacturing. A 30g bowl of any Kellogg's cereal provides 50% of the Reference Intake for vitamin D and 25% for five B vitamins alongside a contribution of iron. The fortification is identical whether you are eating Corn Flakes or Frosties.
Each product page includes a full nutrition breakdown per bowl at four portion sizes, age-adjusted NHS daily free sugar limit calculations for children aged 4 to 17, an interactive calculator for your child's specific age and milk type, and a complete guide to fibre, protein, salt and fortification.
