In fact, it’s absolutely horrifying to discover just HOW much sugar is in our daily morning cereals – especially when you think you’re reaching for a healthy option.

“I would suggest that the aim should be for no more than 1 teaspoon of added sugar in our breakfast cereal,” says Healthy Mummy nutritionist Amanda dos Santos.

“A teaspoon is around 4-5 grams of sugar and it’s recommended that we have around 6 teaspoons of sugar each day. 

“Many breakfast cereals have added sugar in them yet due to labelling, it is difficult to see how much has been added as currently, legally, the food manufacturers are not required to report it.

So, just how much sugar is in our cereal? We’ve put together a list of popular breakfast cereals and the amount of sugar each contain and which ones really are healthy or not…

Kellogg’s Sustain has 19.4g of sugar per 100 grams.

And while we know that a serving of cereal is supposed to be around 40g, Amanda says from a comparison point of view, per 100 grams is the best tool.

“Each food item’s serving size is different and therefore 100g lend it to an equal comparative,” she says.

“Just a note of caution, the sugar reporting for nutritional information panels does not necessarily mean added sugar, it is sugar in entirety. So if you have a food item with milk products or fruits products in there, this sugar level may be in fact higher.

“This is the whole issue with the reporting of sugar at the moment, it doesn’t differentiate the added sugars or extrinsic sugars (like honey, cane sugar etc) from  the intrinsic sugars such as fructose and lactose found in fruit and milk products respectively.”

However, these cereals contain less than 10 grams of sugar per serving:

Uncle Toby’s Quick Oats has 1 gram of sugar per 100 grams.

Weet-Bix has 3g of sugar per 100 grams

Wow, there you have it! How interesting is that?
