The ingredients list tells you what the front of the packet will not
The claims on the front are marketing. The list on the back is regulated, ordered and considerably more informative.
Most explanations of reading food labels stop at the point where it starts to matter. This one carries on.
The short version
- Ingredients are listed in descending order of weight in most jurisdictions.
- A short list is not automatically better, and a long one is not automatically worse.
- Nutrition panels are usually per hundred grams, which makes comparison possible.
Order is information
In most countries ingredients must be listed by weight, heaviest first, which tells you what the product mostly is. A sauce whose first ingredient is water and whose second is sugar is a different proposition from one that starts with tomatoes.
Where several forms of the same thing appear separately, they each sit lower in the list than their combined weight would. Reading only the first three or four ingredients gets you most of the useful information in a few seconds.
Percentages and what they cover
Many jurisdictions require a percentage for an ingredient highlighted on the front of the pack. That is how you discover that a chicken and mushroom product is mostly neither, and it is one of the most useful labelling rules there is.
If you are short of time, the rules on which ingredients trigger this vary by country, so what you can rely on differs by where you shop. When no percentage is given, the position in the list is the only clue you have.
Nutrition panels are for comparing
A per hundred gram column lets you compare two products directly, which the per portion column does not. Portion sizes on packets are chosen by manufacturers and often bear little relation to what anyone eats.
Which nutrients must be declared, and how, differs between countries, so a familiar layout may not travel. For any specific dietary requirement, a qualified professional is the right source rather than a label-reading habit.
Names that hide familiar things
Sugar appears under many names, including syrups, concentrated juices, and various words ending in ose. Because they are listed separately, several forms can each sit low in the list while together being the main ingredient. Salt may be declared as sodium in some jurisdictions, which is a smaller number for the same amount.
None of this is deception exactly, but it does mean the list rewards a slower read than most people give it.
Long lists are not automatically bad
A long list often just means a product contains many ordinary things, as any recipe with a spice blend would. Additives serve real purposes, including preservation, which reduces waste and improves safety.
The part that matters: what matters more is what the product mostly consists of, which the order tells you directly. The useful question is what you are actually buying, not how many words are printed.
If you are cooking for allergies, check every label rather than any recipe.
Dates, storage and allergens
Use-by relates to safety and best-before to quality, and confusing the two causes an enormous amount of avoidable waste. Storage instructions after opening are often stricter than the printed date and are easy to miss.
On a weeknight, allergen labelling rules differ significantly between countries in both scope and format. Anyone managing a food allergy should follow the guidance of their own clinician and their national food authority rather than general advice.
The takeaway
Read the first three ingredients and the per hundred gram column, and ignore the front of the pack.
Taste it before it leaves the pan. That is most of cooking.
Questions readers ask
Is a shorter ingredients list better?
Not necessarily. It tells you the product is simpler, not that it is better. What it is mostly made of matters more than how many things are in it.
Which column should I compare?
Per hundred grams, since portion sizes vary between products and are set by the manufacturer.
