How to Read Food Labels: Serving Size, Sugar and %DV
Start with the whole US label: amount, chosen nutrient, sugar relationship and separate ingredient checks.
Find the label question
Choose the problem on the pack: which amount a column describes, why a pure sweetener shows added sugars, what UK colours mean, or how to compare foods at matching quantities. Eight guides connect the reading step with usable breakfast examples.
Identify the quantity and the kind of label before drawing a conclusion.
Start with the whole US label: amount, chosen nutrient, sugar relationship and separate ingredient checks.
Per-serving and per-package columns are two descriptions of the same food, not two amounts to add. Choose the heading that matches what you are considering, then scale by one route. A whole-package column already includes the package’s servings.
An added-sugars percentage on pure honey or pure maple syrup does not, by itself, mean another sugar was mixed in. US labels have a special presentation for single-ingredient sugars and syrups. Read the ingredients, serving and any footnote together, then keep the contribution separate from the question of how the product was made.
Compare sodium at equal quantities, read US %DV and calculate a known food subtotal. Two fictional tables and four complete checks keep serving sizes, missing values and front-label claims visible.
Read the UK front boxes with the portion and matching back-table figures.
UK traffic light boxes describe individual nutrient levels: red is high, amber medium and green low. Read them alongside the stated portion and the back or side nutrition table. A colour, a reference-intake percentage and a nutrient’s gram amount answer different questions.
Compare equal weights, account for each ingredient once and keep product recipes visible.
Use the two current, attributed UK product examples to distinguish declared servings and equal weights.
Scale each actual ingredient for the amount used; preserve missing nutrient values and incomplete totals.
Check named fruit recipes, packing liquids, no-added-sugar asterisks and appropriate storage.
Keep the exact product, market, serving quantity, preparation state and label heading with your conclusion. The original calculations and practice cases teach interpretation; they are not food analyses or a personal dietary prescription.
A favourable nutrient number does not settle an ingredient or allergy question. Use the relevant instructions and any prescribed dietary plan.
