Seven label checks for any snack
No single check classifies a food. Together they build a quick picture in the time it takes to pick up the pack.
- Read the whole list, not the front. Words like “high protein” or “made with real fruit” are front-of-pack claims. The ingredient list is the part that tells you what is inside.
- Notice the length. A long list of unfamiliar words points to a formulated food. A short list of things you could buy separately points the other way.
- Spot sugar under other names. Glucose syrup, dextrose and fruit juice concentrate all count. See the full sugar names list.
- Look for emulsifiers and texture agents. Lecithin, E471, xanthan gum and carrageenan shape texture. See emulsifiers explained.
- Find the isolates and modified ingredients. Soy protein isolate, modified starch and hydrolysed protein are not kitchen ingredients.
- Check the flavour and colour words. “Flavouring”, “natural flavour”, caramel colour and E1xx numbers are cosmetic additives.
- See how protein and fibre were added. Isolates, inulin and polydextrose can make a snack look “high protein” or “high fibre” without being whole foods.

Frequently asked questions
How can I tell if a snack is ultra-processed?
Read the ingredient list for markers: sugars under other names, protein isolates, modified starch, flavourings, emulsifiers and cosmetic colours. One marker or more points to the NOVA ultra-processed group; the rest of the list and the method of making are context.
Is “high protein” on the front a clue?
It is a claim, not a classification. Protein can come from whole foods such as nuts or from isolates. The ingredient list shows which.
Are all packaged snacks ultra-processed?
No. Simple packaged snacks such as plain nuts, plain popcorn or oats with no additives are minimally processed. The packaging does not decide it; the ingredients and process do.
What if an ingredient is not on your list?
The label checker only matches selected terms. A missing match does not classify a food, so use the full list as context.
