Food Labelling & Marketing
Understanding food labels, traffic light labelling, nutritional information, allergen declarations, and how marketing influences consumer food choices.
Key Fact: Food labels are legally required to provide: name of the food, ingredients list (in descending order of weight), allergen information, net quantity, use-by or best-before date, storage instructions, and name/address of the manufacturer.
Key Fact: The traffic light labelling system uses colour coding: green (low — healthier choice), amber (moderate), red (high — eat in smaller amounts or less often) for fat, saturated fat, sugars, and salt.
Key Fact: Use-by dates are about safety: food should NOT be eaten after its use-by date, even if it looks and smells fine (particularly for high-risk foods like meat and dairy).
Key Fact: Best-before dates are about quality: food is at its best before this date but is usually still safe to eat afterwards (e.g. dried pasta, tinned goods).
Key Fact: The 14 major allergens that must be declared on labels are: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, nuts, peanuts, sesame, soybeans, and sulphur dioxide.
Key Fact: Nutritional information must show energy (kJ/kcal), fat, saturated fat, carbohydrate, sugars, protein, and salt per 100g (and often per serving).
Key Fact: Food marketing techniques include: health claims (e.g. 'low fat', 'high in fibre'), attractive packaging, celebrity endorsements, brand loyalty campaigns, and BOGOF (Buy One Get One Free) offers.
Key Fact: Food claims are regulated: a product can only claim 'low fat' if it contains no more than 3g of fat per 100g; 'sugar-free' means no more than 0.5g of sugar per 100g.
Key Fact: Marketing can mislead: a 'low fat' product may be high in sugar; 'no added sugar' does not mean sugar-free (fruit contains natural sugars).
Key Fact: The Reference Intake (RI) on labels shows the maximum daily amount of nutrients an average adult should consume, helping consumers make informed choices.

❓ Practice Questions
Q: What is the difference between a use-by date and a best-before date?
Q: What do the three colours in the traffic light labelling system mean?
Q: List four of the 14 major allergens that must be declared on food labels.
Q: What must a product contain to be labelled 'low fat'?
Q: Why can food marketing be misleading? Give an example.
Q: What seven nutrients must be shown on nutritional information labels?
Q: In what order must ingredients be listed on a food label?
Q: What is the Reference Intake (RI) on a food label?
✅ Answers
- A use-by date is about safety — food should not be eaten after this date. A best-before date is about quality — food may still be safe to eat after this date but may not be at its best.
- Green = low (healthier choice), amber = moderate, red = high (eat less often or in smaller amounts). They apply to fat, saturated fat, sugars, and salt.
- Celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, nuts, peanuts, sesame, soybeans, sulphur dioxide (any four).
- No more than 3g of fat per 100g of the product.
- Marketing focuses on positive aspects while downplaying negatives. Example: a 'low fat' yoghurt may be high in sugar; 'no added sugar' does not mean the product is sugar-free.
- Energy (kJ/kcal), fat, saturated fat, carbohydrate, sugars, protein, and salt.
- In descending order by weight — the ingredient present in the largest amount is listed first.
- The RI shows the recommended maximum daily amount of key nutrients for an average adult, helping consumers understand how a product fits into their daily diet.
🎯 Exam Tips
- Know the difference between use-by and best-before — this is a very common exam question.
- When asked about traffic light labels, state what each colour means AND which nutrients are colour-coded (fat, saturated fat, sugars, salt).
- Be ready to list at least 4 of the 14 allergens — examiners do not usually require all 14.
- When discussing marketing, always explain HOW a technique influences consumer behaviour, not just what it is.
📝 Exam Technique
Food Preparation & Nutrition Exam Tips — Food Labelling & Marketing:
1. For Food Labelling & Marketing questions, show every step of your working clearly — method marks count even if the final answer is wrong
2. Check your answer makes sense in context (estimation, units, reasonableness)
3. Use correct mathematical notation and state formulae before substituting values
4. If a Food Labelling & Marketing question asks you to 'prove' or 'show', write a logical chain of reasoning with a conclusion line
5. For problem-solving, identify the topic first, then recall the relevant method

⚠️ Common Errors
✗ Best-before and use-by dates mean the same thing. ✓ Use-by dates are about food safety — food must not be eaten after this date. Best-before dates are about quality — food may still be safe afterwards.
✗ If a food has a green traffic light it is always healthy. ✓ A green traffic light means the food is low in that specific nutrient (fat, saturated fat, sugar, or salt). A food could be low in fat but high in sugar, so you need to check all four indicators.
✗ 'No added sugar' means the product contains no sugar. ✓ 'No added sugar' means no sugar has been added during processing, but the product may still contain naturally occurring sugars (e.g. from fruit).
✗ All food labels are voluntary. ✓ Most food labelling information (name, ingredients, allergens, use-by date, nutritional information) is required by law. Only front-of-pack traffic light labelling is currently voluntary.
✍️ Model Answer
Full-Mark Response
Explain how food labelling helps consumers make informed food choices, using the traffic light system and allergen information as examples. (6 marks)
Food labelling provides essential information that helps consumers make safe and informed dietary choices. The traffic light labelling system on the front of packaging uses green, amber, and red colour coding for fat, saturated fat, sugars, and salt per serving. Green indicates a low and therefore healthier amount, amber is moderate, and red means the food is high in that nutrient and should be eaten in smaller amounts or less often. This allows consumers to quickly compare products at a glance and choose the healthier option without needing to read detailed nutritional data. Allergen information is equally important: by law, the 14 major allergens (including nuts, milk, eggs, gluten, fish, and sesame) must be clearly highlighted on the ingredients list, typically in bold or a different colour. This enables people with food allergies or intolerances to quickly identify whether a product is safe for them to consume, which is critical because allergen exposure can cause severe reactions including anaphylaxis. Together, these labelling systems support informed decision-making: traffic lights address long-term health by guiding nutrient intake, while allergen declarations address immediate safety for vulnerable consumers.
