The front of a package is advertising. “High in fibre,” “no added sugar,” “made with real fruit” — these are claims designed to sell, and they’re often technically true while still being misleading. The Nutrition Facts label on the back is the part that’s actually regulated, and once you know which lines to read, it takes about ten seconds.
Here are the four that matter most.
1. Serving size — read this first
Everything else on the label is calculated per serving, and the serving size isn’t a recommendation of how much to eat. It’s just the basis for the math. A bag of chips might list 150 calories — per serving — while the bag holds three servings. If you eat the whole thing, multiply everything by three.
Always start here, because it changes how you read every line below it.
2. Added sugars — the line that changed everything
Total sugars include the natural sugars in things like fruit and milk. Added sugars are the ones put in during processing — table sugar, syrups, concentrated juices — and they’re now listed on their own line with the word “Includes” before them.
This is the single most useful number on the label. A container of plain yogurt and a container of flavoured yogurt can show similar total sugar, but the flavoured one’s added-sugar line tells the real story. The Daily Value for added sugars is 50 grams per day — and most of us do better staying well under that.
3. Dietary fiber — a number you want to be high
Fiber slows digestion, steadies blood sugar, and keeps you full. Most adults need 25 to 38 grams a day, and most of us fall short. The Daily Value used on labels is 28 grams, so a food contributing a meaningful share of that is worth noticing — especially in breads, cereals, and snacks where fiber is easy to lose in processing.
4. The %DV shortcut
To the right of most nutrients is a % Daily Value. You don’t need to memorise milligrams — just use this rule of thumb:
- 5% DV or less is low
- 20% DV or more is high
So you want low %DV for the things to limit (added sugar, sodium, saturated fat) and high %DV for the things to get more of (fiber, calcium, vitamin D, iron). One glance tells you which way a food leans.
And one line that isn’t a number
The ingredients list is ordered by weight, most to least. If sugar (under any of its many names) is in the first three ingredients, you’re holding a sweet food, whatever the front of the pack says. A short list of recognisable ingredients is usually — though not always — a good sign.
You don’t have to become a label obsessive. But knowing these few lines means the marketing on the front stops doing your thinking for you.
