Serving sizes
A printed serving may not match the quantity eaten, so comparisons should use the same basis.
FOOD LITERACY · 2026
Reading food labels with context
Labels can help compare products, but they cannot describe every part of a person’s diet, culture, budget or health situation.
What each part can tell you
| Label area | Information offered | Question to ask |
|---|---|---|
| Ingredients | Ingredients are generally listed by weight. | Are there allergens or ingredients to discuss? |
| Nutrition panel | Values are shown per 100g or serving. | Are the serving sizes comparable? |
| Storage | Directions after opening or preparation. | Can the product be stored as stated? |
| Date mark | Use-by and best-before wording differs. | Which instruction applies to this food? |
A calm label-reading checklist
- Start with the product name and intended use.
- Check the ingredients list for known allergens.
- Compare like-for-like serving information.
- Read storage and preparation directions.
- Consider cost, taste, access and the rest of the meal.
Three common sources of confusion
Front-of-pack language
Short descriptions are selective. The ingredients and nutrition panel provide fuller context.
Different products
Two products may use different formats, so compare the relevant information carefully.
Questions readers ask
Do labels tell the whole story?
No. They describe a product, not a complete eating pattern or personal circumstance.
Should one number decide a purchase?
It is more useful to consider several details alongside price, taste, access and household needs.
Allergy information
People managing an allergy or intolerance should follow current official guidance and seek individual advice when label wording is unclear.
“A label becomes useful when it is read alongside the question a shopper is actually trying to answer.”
Shopping prompts
- Is the serving comparison like-for-like?
- Are storage instructions clear?
- Does the product suit the household?
Label reading is most useful when connected to a real shopping decision.
