Crunchy Nut nutrition: sugar, fibre, protein, fortification and more

A 30g bowl of Kellogg's Crunchy Nut contains 10.5g of free sugar, which is 44% of the daily limit for a child aged 7 to 10 and 55% for a child aged 4 to 6. A 40g bowl contains 14g, which is 58% of the daily limit for a child aged 7 to 10. Per 100g, Crunchy Nut contains 35g of sugar, placing it among the higher-sugar options in the Kellogg's range.

Per 100g: 35g sugar, 392 kcal, 0.85g salt, 3g fibre, 6.5g protein. Per 30g bowl with 125ml semi-skimmed milk: 10.5g free sugar, 177 kcal, 0.5g salt, 0.9g fibre, 6.2g protein. Per 40g bowl with 125ml semi-skimmed milk: 14g free sugar, 216 kcal, 0.5g salt, 1.2g fibre, 7.0g protein. Milk lactose does not count as free sugar under NHS guidelines.

Yes. Despite being marketed at adults with honey and nut branding, Crunchy Nut contains 35g of sugar per 100g, which is almost identical to Coco Pops at approximately 35g per 100g. A 30g bowl of Crunchy Nut uses 44% of the daily free sugar limit for a child aged 7 to 10, comparable to the most sugar-heavy children's cereals. The adult positioning does not reflect a meaningfully different nutritional profile.

Yes. Under NHS guidelines, honey counts as a free sugar. Free sugars include all sugars added during manufacturing, as well as sugars naturally present in honey, syrups and fruit juice. The honey coating on Crunchy Nut counts in full toward the NHS daily free sugar limit. It is treated the same as any other added sugar regardless of its natural origin.

Yes. Kellogg's Crunchy Nut contains peanuts, which are listed in the ingredients and highlighted as an allergen. Peanuts are one of the 14 major allergens regulated under UK food law. Crunchy Nut is not suitable for anyone with a peanut allergy or tree nut sensitivity. It is the only cereal in the Kellogg's range covered in this guide that contains nuts as a named ingredient.

The NHS recommends no more than 19g of free sugar per day for children aged 4 to 6, 24g for children aged 7 to 10, and 30g for anyone aged 11 and over. A 30g bowl of Crunchy Nut contains 10.5g of free sugar from the cereal alone. Milk lactose does not count toward this limit. A 60g bowl uses 88% of the daily limit for a child aged 7 to 10 from breakfast alone.

No. Crunchy Nut is made from corn that has been refined rather than left as whole grain. This is reflected in its low fibre content of 3g per 100g. The bran and germ layers that contain most of a grain's natural fibre are removed during refining. By comparison, wholegrain cereals such as Shredded Wheat contain around 10g of fibre per 100g. Crunchy Nut is not a wholegrain product despite the presence of peanuts and honey.

A 30g bowl of Crunchy Nut with 125ml semi-skimmed milk contains approximately 177 calories. A 40g bowl with milk contains 216 calories, a 50g bowl contains 255 calories and a 60g bowl contains 294 calories. For a child aged 4 to 6 with a daily energy need of around 1,400 calories, a 30g bowl represents approximately 12% of their daily requirement.

Yes. A 30g bowl of Crunchy Nut provides 50% of the Reference Intake for vitamin D and 25% for thiamin, riboflavin, niacin, vitamin B6, folic acid and vitamin B12, alongside a contribution of iron. Fortification is standard practice for UK breakfast cereals. Vitamin D is particularly relevant for UK children, many of whom have low vitamin D status especially during winter months.

Yes. Under the NOVA classification system, Crunchy Nut falls into group 4, ultra-processed foods. This classification reflects the combination of refined corn with added sugar, honey flavouring, peanuts and the industrial processing methods used to create the final coated flake. NOVA group 4 includes the majority of packaged breakfast cereals regardless of whether they contain natural ingredients such as honey or nuts.

Crunchy Nut contains 35g of sugar per 100g compared to approximately 37g per 100g in Frosties, making them very close in sugar content. A 30g bowl of Crunchy Nut delivers 10.5g of free sugar versus approximately 11g from a 30g bowl of Frosties. Both are among the highest-sugar cereals in the Kellogg's range. The key difference is that Frosties is openly marketed at children while Crunchy Nut uses adult-oriented branding despite a comparable sugar profile.

Crunchy Nut contains 0.85g of salt per 100g. A 30g bowl contains 0.3g of salt. With 125ml semi-skimmed milk, the total rises to approximately 0.5g. For a child aged 4 to 6 with a daily salt limit of 3g, a 30g bowl with milk represents around 17% of their daily allowance from breakfast. Salt is a secondary concern with Crunchy Nut compared to its high sugar content.

Crunchy Nut contains 3g of fibre per 100g, which is 0.9g in a 30g bowl. This is low for a breakfast cereal and reflects the refined corn base. The peanut pieces add a small amount of additional fibre but not enough to meaningfully change the per-bowl figure. By comparison, All-Bran Original contains 24g of fibre per 100g and Bran Flakes contains around 15g per 100g.

Semi-skimmed or skimmed milk adds calcium, protein and vitamin D without additional free sugar. Given that Crunchy Nut already delivers 10.5g of free sugar per 30g bowl, choosing an unsweetened milk is important to avoid adding further sugar to an already high-sugar bowl. Oat milk can contain added sugar so check the label before using. Whichever dairy milk you choose, the lactose does not count as free sugar under NHS guidelines.

Crunchy Nut contains 6.5g of protein per 100g, which is 2g in a 30g bowl before milk. With 125ml of semi-skimmed milk, which contributes approximately 4.2g of protein, the total reaches 6.2g. For a child aged 7 to 10, a 30g bowl with milk provides around 26% of the daily protein guide of 24g. As with most cereals, the majority of the protein in the bowl comes from the milk rather than the cereal, with the peanut pieces contributing a small additional amount.
