Kellogg’s Crunchy Nut vs supermarket honey nut cornflakes

We pitted Kellogg’s Crunchy Nut cornflakes against cheaper supermarket own brands in a blind taste test to find out if it’s worth paying more for a big-brand cereal

Combining sweet honey, chopped peanuts and crunchy cornflakes, Kellogg’s Crunchy Nut is one of the most popular breakfast cereals in the UK.

But with many supermarkets offering cheaper own-brand honey nut cornflakes - often for less than half the price - opting for a supermarket cereal could lead to significant savings on your shopping bill over time.

In August 2021, we tested Kellogg’s Crunchy Nut alongside seven supermarket honey nut cornflakes from the likes of Aldi, Asda and Tesco.

We uncovered some bargain breakfast cereals with a lovely, nutty flavour and perfect crunch – but others were less impressive. Keep reading to find out which cereals topped our taste test.

Are honey nut cornflakes healthy?

Person eating cornflakes

They may be a tasty start to the day (or evening snack - just me?), but it's worth bearing in mind that all the honey nut cornflakes we reviewed were pretty high in sugar.

As Shefalee Loth, Which? nutrition expert, explains: ‘After maize, the main ingredient in all these cereals is sugar - and they all also contain other forms of "hidden" sugar such as honey, molasses and syrups.

'Some have vitamin D added in, although this is a relatively small amount of your daily requirements. Kellogg's Crunchy Nut contains 25% of the recommended daily dose in a 30g portion, while others contain only 15% (it's worth noting that previous Which? research revealed that most people actually eat much bigger cereal portions than the recommended amount).

'Kellogg's Crunchy Nut contains the most sugar of the honey nut cornflakes tested at 35g of sugar per 100g. That's nearly three teaspoons of sugar per 30g portion (see note above regarding portion size). 

'Supermarket own-brand versions are better - most contain around 28g of sugar per 100g, 20% less than Kellogg's. But that's still high - they all get a red traffic light (high rating) for sugar, except for Lidl's version - which has a medium sugar rating.'

Which breakfast cereals have the most sugar?

Kellogg’s Crunchy Nut packs in a lot of sugar, but how do other options measure up?

We compared the amount of sugar in popular branded breakfast cereals* and ranked them from most to least sugar per 100g and found there was wide variation, so it pays to pay attention to what you pick up from the cereal shelf.

Kellogg's Crunchy Nut topped the table, but Kellogg's Krave Milk Chocolate isn't far behind. Both are classed as high in sugar as they contain more than 22.5g per 100g.

*Most popular ready to eat cereals from The Grocer's Top Products Survey 2020 based on sales data from Nielsen Scantrack.

Most of the most popular cereals we looked at have a medium sugar rating, including Kellogg’s Coco Pops, Kellogg’s Special K and Kellogg’s Rice Krispies.

If you’re looking to switch to a less sugary cereal, Weetabix and Nestlé Shredded Wheat are good options, as both are classed as low in sugar.

Weaning yourself on to plain cornflakes (perhaps for weekdays) would also be a good switch as these contain a fraction of the sugar of the crunchy nut versions.

How to recycle cereal packaging

Cereal boxes

Cardboard cereal boxes can usually go in your household recycling bin.

The inner plastic bags can’t go in your household recycling bin, but you may be able to recycle them along with carrier bags at some supermarkets, if they have soft plastic bins.

How we taste-tested honey nut cornflakes

The cereals were served with semi-skimmed milk and assessed by a large panel of consumers who regularly buy and consume this type of product.

The make-up of the panel broadly represents the demographic profile of adults in the UK. 

Each cereal was assessed by 67 people.

The panellists rated the taste, texture, aroma and appearance of each product, and told us what they liked and disliked about each one. 

The taste test was blind, so the panellists didn’t know which brand they were trying. The order they sampled the cereals was fully rotated to avoid any bias. 

Each panellist had a private booth so they couldn’t discuss what they were tasting or be influenced by others.

The overall score is based on:

  • 50% taste
  • 20% texture
  • 20% aroma
  • 10% appearance
