Buying breakfast cereals: how to choose the right option without falling for marketing traps

Buying breakfast cereal seems straightforward until you start comparing supermarket shelves and online shops. Granola, porridge oats, crunchy muesli and protein muesli can vary considerably in sugar, fibre, protein, portion size and allergens. What stands out on the front of the pack doesn’t always tell you enough about what’s inside.

This practical guide focuses on the information that really matters. It’ll help you find breakfast cereal to suit your eating habits, workouts, family and budget.

Three common breakfast cereal pitfalls

1. Confusing “no added sugar” with sugar-free

The claim no added sugars doesn’t automatically mean that a product contains no sugar. Ingredients such as fruit, date concentrate or milk products can provide naturally occurring sugars. So always check the nutritional information under “of which sugars” and read the ingredients list.

For example, Quaker Cruesli Choco Zero Sugar states that it contains no added sugars and no sweeteners, but according to the product information, it still contains 3.4 grams of sugar per 100 grams. That’s not the same as being completely sugar-free.

2. A high protein content doesn’t tell you everything

High-protein breakfast cereals can be useful for active adults or anyone who wants more protein at breakfast. However, a high protein percentage can go hand in hand with relatively high levels of calories, fat or fibre that not everyone tolerates well.

So look at the full nutritional profile per 100 grams and per recommended serving. Check the protein source, too. This could be wheat protein, pea protein, soya or peanuts, for example. That information matters if you have allergies or personal preferences.

3. “Granola” often means extra fat and calories

Granola and crunchy muesli are usually baked. This gives them a crunchy texture, but they may also contain more oil, nuts or seeds than plain porridge oats. That’s not necessarily a problem, but portion size matters.

A generous bowl can easily be much larger than the serving suggested on the pack. When comparing products, use the same amount, such as 30 or 40 grams, and add yoghurt, milk and fruit as you like.

Which nutritional values should you check?

Fibre: check the figure per 100 grams

If you’re looking for high-fibre breakfast cereals, it’s worth comparing the fibre content directly. Porridge oats, wholegrain cereals and products containing chicory root fibre can all differ.

According to the nutritional information provided, Quaker Oatmeal contains the following per 100 grams:

  • 9 grams of dietary fibre;
  • 11 grams of protein;
  • 1.1 grams of sugar;
  • 100% wholegrain oats as an ingredient.

The information about beta-glucans and cholesterol is a health claim made by the manufacturer. According to Quaker’s product information, this claim refers to the role of beta-glucans in oats as part of a varied diet and healthy lifestyle. It shouldn’t be taken as personal medical advice.

Protein: compare the source, amount and serving size

Protein muesli doesn’t necessarily contain more protein per serving than regular muesli eaten with yoghurt. Check:

  1. the protein content per 100 grams;
  2. the suggested serving size;
  3. the protein source used;
  4. any allergens, such as soya, milk, gluten, peanuts and nuts.

Some products also contain a lot of fibre from chicory root. This can contribute to a high-fibre recipe, but a large serving may not suit everyone. When trying a new product, start with the recommended amount.

Sugar, fat and the ingredients list

Don’t just look at the front of the pack for terms such as “chocolate”, “natural” or “low sugar”. Ingredients are listed in descending order by weight. Check whether oats, wholemeal wheat or other grains appear near the top, and what role oil, syrups, date concentrate, cocoa and fibre ingredients play.

With chocolate granola, cocoa isn’t the same as lots of sugar, but the overall nutritional value is what counts. With sugar-free breakfast cereals, you should also check whether sweeteners are used. “No added sugar” and “no sweeteners” are separate claims.

  • Compare sugars, fibre and protein per 100 grams.
  • Check whether “no added sugars” means what you expect it to.
  • Read the ingredients list and allergen information.
  • With granola, check the oil, nuts and serving size.

  • Store opened products in a dry place and keep them tightly sealed.
  • Check the best-before date and packaging when your order arrives.

Frequently asked questions about buying breakfast cereals

Which breakfast cereals are relatively high in fibre?

It depends on the recipe. In the examples mentioned, Quaker Oatmeal contains 9 grams of fibre per 100 grams, while some protein mueslis and granolas contain more than 20 grams per 100 grams, according to their product information. Always compare the label and take the serving size into account.

Are breakfast cereals with no added sugars sugar-free?

No. “No added sugars” means that no sugar or similar sweetener has been added as an ingredient during production. The product may still contain naturally occurring sugars. So check the “of which sugars” line.

How long does breakfast cereal keep after opening?

Follow the storage information on the pack. Keep breakfast cereal in a cool, dry place in a sealed container, away from moisture and direct sunlight. If it has gone soft, smells unusual or the packaging is damaged, it’s best not to use it.
