You're in the supermarket. You pick up a snack that looks perfectly reasonable, flip it over to check, and... a wall of tiny numbers stares back.
Overwhelmed, you pop it in the trolley and move on. We've all done it.
Here's the good news. You don't need a nutrition degree to read a label. You need about 60 seconds and five little tricks. Let's crack the code.
First, ignore the front of the pack
The front of the pack is marketing. “No artificial colours!” “Made with real fruit!” “A source of calcium!” All technically true, all designed to make you feel good and stop reading.
The bit you actually want lives on the back, in the boring little table and the ingredients list. That's where the real story is, so here are five tricks you can use to quickly work out if it's something you really want in your basket.
Trick 1: Read the ingredients top to bottom
Here's the rule not many people know: ingredients are listed in order of weight, most first.
So the first three or four ingredients in the list are a good indication of what the product actually is. If sugar (or one of its many aliases, more on that in a second) shows up in the top ingredients, you're holding something that is, by weight, mostly sugar. No matter what the front says, it's a sweet snack.
Trick 2: Learn sugar's disguises
This is the sneaky bit. Sugar hides under more than fifty different names. Brands know that if “sugar” is the first ingredient you'll clock it, so they'll often split it into three or four different types instead. Suddenly no single sugar is near the top, even though, added together, sugar is the main ingredient.
You don't need to memorise all fifty. Remember these two shortcuts instead:
• Anything ending in “-ose” is a sugar. Glucose, fructose, sucrose, dextrose, maltose. If you see “-ose”, read “sugar”.
• Anything called a syrup, a concentrate, or a “juice” is almost always sugar too. Glucose syrup, rice syrup, fruit juice concentrate. All sugar, in disguise.
See three or four of these scattered through one ingredients list? That's the split-it-up trick in action.
Trick 3: Use the “per 100g” column, not per portion
The nutrition table usually has two columns: “per 100g” and “per portion”. Your eye goes to per portion, because the number is smaller and more comforting. Here's the catch: a “portion” is whatever the manufacturer decides it is. They can make a portion tiny on paper to keep the numbers looking lovely, even if no actual child has ever eaten just one.
The “per 100g” column is the better bet. It's the only way to fairly compare two products side by side, because it doesn't move the goalposts. Two cereals? Compare the per-100g numbers. Job done.
Handy rule of thumb for the traffic lights: on that per-100g column, 5g of sugar or less is low (green), and more than 22.5g is high (red).
Trick 4: Put it into perspective
Grams are simply a number. Nobody pictures 27g of sugar.
Let's turn it into sugar cubes and compare it to the maximum amount of sugar recommended by the NHS per day.
For example, children aged 4 to 6 should have no more than 19g of free sugars a day (5 sugar cubes).
4g of sugar is roughly one sugar cube. So just divide the sugar number by 4.
That “healthy” yoghurt with 20g of sugar? Five cubes. For a 5 year old, that's already a full day's sugar allowance in one pot.
The cereal at 12g a bowl? Three cubes, before they've even left for school.
Once you start seeing the numbers in cubes, it's very hard to switch it off.
Trick 5: Now look for the good stuff (protein and fibre)
A genuinely good kids' snack isn't just low in sugar, it's actually got something useful in it. The two things worth hunting for are protein and fibre, because they're the tag-team that keeps little tummies full and blood sugar steady between meals (which, as we covered in a previous article, is half the battle with the 4pm meltdown).
Here are the rule-of-thumb numbers:
• Fibre: 3g per 100g is a “source of fibre”, 6g per 100g or more is officially “high in fibre”. The higher the better.
• Protein: a snack with around 5g or more is a properly filling one. Enough to actually tide a child over, rather than leaving them rummaging in the cupboard twenty minutes later. It's the one where a lot of kids' snacks fall short.
One last trap to watch out for. A big “HIGH IN PROTEIN!” flash on the front doesn't always mean much. Some snacks bump up the protein number, then load the thing full of sugar. If the sugar number is higher than the protein number, it's not as healthy as you first thought.
So do the full check: protein and fibre up, sugar down, and a short ingredients list you can actually pronounce. That combination is the real green flag.
BONUS TIP: that ingredients list tells you one more thing - how processed the snack is.
Short list, things you recognise? Good sign. Long list that reads like a chemistry set? Usually a heavily processed one.
Watch for three regulars: sweeteners (aspartame, sucralose, acesulfame-K), preservatives, and artificial colours and flavourings. None are banned or dangerous, they're all safety-checked. They're just a clue to how processed a snack is.
Sweeteners come with a sting in the tail, though. Swap sugar for sweeteners and you keep kids hooked on very sweet tastes, which is the exact habit most of us are trying to dial down. Less sweet, full stop, is the goal.
The takeaway
That's it. Five tricks, 60 seconds. Sugar down, protein and fibre up, and a quick sense-check on the ingredients.
Fair warning though. Once you can read a label properly, you can't unsee it. That comforting “healthy kids' snack” in your cupboard right now might not survive the flip test, and you'll never quite look at it the same way again.
