This information isn't always obvious from the front of the pack and brands display their nutrition guides differently. Therefore, it’s up to us, the consumers, to examine the nutrition label (usually found on the back) of the packet to see how much sugar it contains.
As a quick guide, any food which has 5g of sugar or less per 100g is a low sugar food. In teaspoon terms, 4.2g is one teaspoon.
Food which has more than 15g of sugar per 100g is ‘high in sugar’. So check the label under the ‘Per 100g’ column. All labels should display this information.
If you’re determined to find a low sugar cereal, they are out there, but they’re few and far between!
Following are 16 Breakfast Cereals which are low in sugar:
1. Porridge Oats 0.5g - 1.5g
Porridge oats are made with wholegrain rolled oats and nothing else. Brands achieve their textures and flavours by rolling and milling their oats in different ways.

Oats, including oatbran, provide a good source of soluble fibre and have no added sugar or salt. Most brands of plain porridge oats contain between 0.5-1.5g of naturally occurring sugars per 100g.
Oats with added fruit, syrups and other flavours have much higher levels of sugar. A 50g serving made with water provides around 170 calories.

2. Spelt Flakes 0.5g - 1.7g

Spelt (an ancient form of wheat) has been hailed as a super-food. It’s a great alternative to wheat, and keeps you satisfied for longer than other grains.
Spelt has a delicious nutty taste which some people may find easier to digest than wheat.
Use them as a substitute for regular oats to make porridge, or mix half oats and half spelt flakes. Alternatively, just add cold milk and some dried fruit and nuts to make a muesli. A 50g serving with 125ml semi skimmed milk provides 215 calories.

Wheat Biscuits are generally a low sugar cereal as long as you stick to the plain varieties. They're made with wholegrains and have a low glycaemic index. This means they keep you fuller for longer by releasing their energy slowly. Plain wheat biscuits are also low in fat and sugar.

Varieties with added fruit, chocolate and syrup etc all have higher levels of sugar.
A 30g serving of Sainsbury's Basics Wholewheat Biscuits when served with 125ml semi skimmed milk provides 183 calories.

14. Low Sugar Cheerios 4.7g
I had to include these as an extra to my top 10 low sugar cereals because Cheerios are such a popular children's breakfast. Low Sugar Cheerios are massively lower in sugar than the other varieties (see post).
Apart from the big reduction in sugar, low Sugar Cheerios are made only from oats, rather than four different grains. Oats seem to be a common theme among the low sugar cereals!
One 30g serving with 125ml semi-skimmed milk
provides 180 calories.

Rude Health Porridge Hazelnut Butter with Cacao - 3.7g of sugar per 100g (less than 1 teaspoon)
See post
It’s interesting to see that basic, value brands tend to have less added sugar than supermarkets regular brands. For example, Tesco Value Corn Flakes have 2.7g of sugar per 100g compared with 8.9g for Tesco Corn Flakes.
Another point to note about the sugar content in cereals, is that not all cereals with a medium or high level of sugar, have added refined sugar. Take Alpen’s ‘No added sugar’ muesli. It has no sugar listed in its ingredients, yet the nutrition label shows a sugar content of 16.3g per 100g, which puts it in the ‘high’ category.
However, this isn’t as bad as it sounds. Alpen’s ‘No Added Sugar’ muesli gets its sweetness from the natural sugars found in the dried fruit content. Because dried fruit contains valuable nutrients, it's a healthier type of sugar, though the effect on blood sugar levels remains similar to refined sugar. There is little difference in calories between the two varieties. Alpen's muesli contains 357 calories per 100g, whereas the No Added Sugar Alpen has 352 calories per 100g.
So don’t get caught out by hidden sugars in your cereals. Reading the nutritional label and the ingredients listed on the packet can tell you all you need to know. This article ‘Serving and Portion Sizes, How to Read Nutrition Labels’ explains how to read nutrition labels, while ‘Guidelines to Healthy and Unhealthy amounts of Fat, Salt and Sugar’ explains how much we need of each nutrient and how much sugar, salt and fat is high, medium or low’.
Becoming more 'sugar aware' can help you make informed decisions about the amount of sugar you're really eating in your breakfast cereal. The information's all there on the pack!
