In this lesson you will learn
- Interpret the core lines of the nutrition table
- Use the ordering logic of the ingredient list
- Tell front-of-pack marketing claims apart from back-of-pack data
- Know what to watch for in the sugar and salt lines
The two faces of a package
The front of a package is marketing space: the colours, the claims and the appetising pictures live there. The back is subject to regulation: the nutrition table and the ingredient list are found there. A literate consumer's first reflex is to turn the package over. Most front-of-pack phrases like natural, no additives or homestyle are legally loosely defined; the numbers on the back rest on measurement.
The front-of-pack picture is a claim too: if the photo carries the words serving suggestion beneath it, there is no guarantee the ingredient shown is in the product. That small phrase is the legal admission of the gap between the picture and the contents.
The nutrition table
The table typically carries these lines: energy (kcal and kJ), fat and saturated fat, carbohydrate and sugars, fibre, protein, salt. Values are given per 100 grams and often per portion; use the 100-gram column for comparison. The sugars line is a sub-item of carbohydrate and can cover both natural and added sugar. Small-looking numbers on the salt line can deceive; it is more meaningful to think of a portion's share against the daily reference value (about 5 grams of salt).
The saturated fat line is given separately beneath total fat, and it is one of the most discriminating lines when choosing between two similar products. Preferring the one with clearly lower saturated fat, at equal energy, is a practical rule in line with guidance.
The ingredient list
Ingredients are listed from most to least by weight; the first three items are the product's true identity. If a fruity-looking product lists fruit near the end, its share in the product is small. Sugar can appear under different names: glucose syrup, fructose, invert sugar, maltodextrin and others. If one product carries several different sugar names, the total sugar share may be higher than the list suggests. Allergen information is usually marked in bold or in a separate statement; for people with allergies it is the most critical line on the label.
The length of the ingredient list is not by itself a measure of quality; but if you see many components you do not recognise, you have gained an idea of how processed the product is.
Claims and what they actually mean
No added sugar says sugar was not added to the product; it does not say the product is sugar-free, and natural fruit sugar may be high. Light-style phrases usually describe one component reduced against a reference product; they do not guarantee low total energy. Phrases like source of fibre or high in protein have legal thresholds, but those thresholds do not make the whole product healthy. The rule is simple: the front claims, the back proves. Before deciding, run the 100-gram comparison.
You do not have to memorise any of these claims; one habit is enough: whatever you read on the front, base your decision on the table on the back.
A common mistake
Treating the label as nothing but the energy line. Two products can carry the same energy with completely different compositions: one from fibre and protein, the other from sugar and saturated fat. Energy alone is not a measure of quality; read the whole table.
Try today
Pick two similar products from the same shelf (two breakfast cereals, for instance) and put their backs side by side: compare energy, sugars, fibre and salt per 100 grams. Also count how many different sugar names you can find in the ingredient lists.
Summary
- The front is marketing, the back rests on measurement; the first reflex is turning the package over
- Use the 100-gram column of the table for comparison; the sugar and salt lines deserve extra attention
- Ingredients are ordered by weight; the first three items are the product's identity, and sugar takes many names
- Claims like no added sugar and light have narrow meanings; judge the product as a whole
