The supermarket aisle has become a costume party. Granola wears hiking boots. Protein bars arrive dressed for the gym. Yoghurt practically carries a yoga mat. Add “natural”, “high protein”, or a picture of a sunlit oat field, and suddenly a snack looks ready to improve your life and answer your emails. But the front of a packet is where food sells itself. The more revealing story often sits on the back.
That does not make every packaged food a nutritional supervillain. Plenty can be convenient, affordable and nutritious. The trick is knowing where to look before a glossy health claim wins you over. You do not need a nutrition degree or a calculator. You just need a better reading order.
Start with the portion
You pick up a bottle of iced coffee. The calories look reasonable. Victory! Then you notice the nutrition figures refer to half the bottle, and you have never met anyone who drinks half an iced coffee and lovingly saves the rest for Tuesday.
This is why portion information deserves an early glance. Energy, fat, saturates, sugars and salt may be shown per portion, while figures per 100g or 100ml make it easier to compare similar products. If your actual portion is much larger than the suggested one, your intake climbs with it. So before judging any number, ask one practical question: How much of this will I actually eat?

A snack can look modest on paper and become far more substantial when the whole packet disappears during one episode of your favourite series. The label did not lie. It simply knew you might be distracted by the cliffhanger.

Read the first ingredients
Ingredient lists have a hierarchy. Ingredients are generally listed in descending order by weight, so the opening names can reveal what makes up much of the product. Imagine a loaf decorated with wheat stalks and words such as “farmhouse”, “grain” and “wholesome”. Very cottagecore. But if refined wheat flour appears first and wholegrain ingredients turn up much later, the packaging may be doing more nutritional storytelling than the recipe.
The same logic works for cereals, snack bars, sauces and yoghurts. What is leading the parade? Whole grains? Nuts? Milk? Fruit? Or refined flour and sweeteners? Still, do not turn the ingredient list into a purity contest.
A long list does not automatically make a food harmful, and an unfamiliar name is not proof of danger. Vitamin C may appear as ascorbic acid, which sounds like something stored in a locked government laboratory. The goal is simpler: check if the main ingredients match the healthy image on the front.
Check sugars wisely
This is where label reading needs a little nuance. The line for “of which sugars” includes sugars naturally present in foods as well as sugars added during manufacturing. That means the number alone does not always tell you where the sugar came from.
A plain yoghurt containing naturally occurring lactose tells a different nutritional story from a heavily sweetened dessert-style yoghurt. Likewise, fruit and a bag of sweets may both contain sugar, but they are not nutritionally interchangeable.

So what can you do? Read the nutrition panel alongside the ingredients list. Look for sweetening ingredients such as sugar, syrups, honey or molasses. If several appear prominently, that gives useful context.
Don’t overlook fibre and salt
Protein gets the celebrity treatment. Fibre and salt are often left backstage holding everyone’s coats. Yet they can tell you plenty. Fibre can help you assess foods such as breads and cereals that trade heavily on a wholesome image. A cereal box may feature fields, wooden spoons and enough rustic typography to open its own farmers’ market, but the nutrition information can reveal how much fibre you are actually getting.
Then there is salt. You expect plenty in crisps. Fair enough. But it can also stack up in breads, soups, sauces, ready meals and savoury foods that do not taste dramatically salty. This is where comparison beats panic. Put two similar products side by side and use the per-100g figures. Which has more fibre? Which contains much more salt?
As a useful guide, more than 1.5g of salt per 100g is considered high, while 0.3g or below is low. Those thresholds give you a quick reality check when two products are competing for your trolley.
Let the traffic lights help
Those familiar red, amber and green markers are useful for comparing similar foods, especially for fat, saturates, sugars and salt. But one colour should never make the decision for you. A red marker does not automatically make a food off-limits, just as a row of green markers does not guarantee nutritional perfection.
Portion size still matters, and so does the rest of your diet. A product can boast “high protein” while also being high in salt, or claim “low fat” while packing in plenty of sugar. Reference intake percentages add another layer of context, but they are broad guides, not personalised advice.
The next time a packet promises vitality or ancient grains, turn it around. Check the portion. Scan the ingredients. Look at the sugars. Compare fibre and salt. Then use the traffic lights to complete the picture. The front of the pack is the trailer. The label tells you what film you actually bought.
