What factors affect the food people choose?

Many factors shape food choice: cost and budget, culture, religion and family tradition, personal likes and dislikes, health and dietary needs, convenience and time, advertising and packaging, peer influence, and what is available in the shops. In Singapore, culture and religion (such as halal or vegetarian eating) and the convenience of hawker food are especially strong influences, and a good answer explains how each factor changes what ends up on the plate.

What information must a food label show?

A food label typically shows the name of the food, the list of ingredients in order of weight (largest first), the net weight or volume, the name and address of the manufacturer or importer, storage instructions, the use-by or best-before date, and often a nutrition information panel. In Singapore many products also carry the Healthier Choice Symbol to help shoppers pick healthier options at a glance.

How do you read a nutrition information panel?

The nutrition information panel lists energy and the amounts of key nutrients (such as protein, fat, saturated fat, carbohydrate, sugar, sodium and fibre), usually per 100 g and per serving. Reading per 100 g lets you compare two products fairly because it uses the same amount of each, while the per serving column tells you what you actually get when you eat a portion. Compare the per 100 g figures to choose the lower-fat, lower-sugar or lower-salt option.

What do nutrition claims such as 'low fat' and 'no added sugar' really mean?

Nutrition claims are regulated phrases: 'low fat' means the food is below a set limit of fat, and 'no added sugar' means no sugar was added during processing, though the food may still contain natural sugars. Claims are true but selective, so a 'low fat' food can still be high in sugar or salt. The safe habit is to ignore the headline claim and check the nutrition information panel for the full picture.

How does advertising try to influence what we buy?

Advertising uses appealing images, celebrities, catchy slogans, special offers, attractive packaging and emotional messages (such as fun, health or family) to make a product seem more desirable than it is. It often highlights one good point while hiding less healthy details. An informed consumer recognises these techniques, looks past the advertising, and checks the label and price before deciding.

What this module demands

This module is about being a smart shopper. SEAB (6073) wants you to explain the many factors that shape food choice, read a food label and its nutrition information panel, interpret nutrition claims and advertising, and bring all of this together to make informed, responsible choices. The written Paper 1 tests this with data-response questions on real labels ("compare the two products and say which is healthier"), and the coursework food study expects you to choose and justify ingredients like an informed consumer. This overview links every dot point in the module.

You can see the full set of dot points at /sg-n-level/nutrition-and-food-science/syllabus/consumer-choices-and-food-labelling.

Why we choose what we choose

Start with factors affecting food choice. Food choice is shaped by cost, culture and religion, personal likes, health needs, convenience and time, advertising, peers and availability. In Singapore, culture and religion (halal, vegetarian) and the convenience of hawker food are strong influences. Explain how each factor changes what is eaten.

Reading food labels teaches you what a label must show, the name, ingredients in order of weight, net weight, manufacturer, storage, date marking and the nutrition information panel, and how to read the panel. Comparing the per 100 g column lets you judge two products fairly.

Cutting through the marketing

Nutrition claims and advertising explains what claims such as "low fat" and "no added sugar" really mean (true but selective) and how advertising uses images, slogans, offers and emotion to persuade. The safe habit is to look past the claim and check the panel.

Making informed consumer choices brings labels, claims, cost and nutrition together so a shopper can choose wisely and responsibly, balancing health, budget and value, and using aids such as the Healthier Choice Symbol.

How this module is examined

Explain food-choice factors with examples. Questions ask which factors affect a person's choice and how. Use specific Singapore examples (halal needs, hawker convenience, budget).
Read and compare labels. Data-response questions give two nutrition panels and ask which is healthier. Compare per 100 g for fat, sugar and sodium.
See through claims and adverts. Questions ask what a claim really means or how an advert persuades, and how a consumer should respond.

Comparing two breakfast cereals on the shelf

A shopper is choosing between two cereals. Cereal A is advertised as "low fat"; Cereal B has no claim. Show how to choose wisely.

step Do not rely on the front-of-pack claim

"Low fat" on Cereal A is true but selective: a low-fat food can still be high in sugar or salt, so the claim alone does not make it the healthier choice.

step Compare the nutrition panels per 100 g

Read the per 100 g column for both. Suppose Cereal A has 1 g fat but 30 g sugar per 100 g, while Cereal B has 3 g fat but only 10 g sugar and more fibre per 100 g. Comparing the same amount shows Cereal B is much lower in sugar and higher in fibre.

step Check the ingredients and any symbols

Cereal B lists wholegrain first and carries the Healthier Choice Symbol, while Cereal A lists sugar near the top. The ingredient order (largest first) confirms Cereal B is the wholegrain, lower-sugar option.

step Weigh up cost and decide

If both are similar in price, Cereal B is the better choice because it is lower in sugar, higher in fibre and wholegrain, despite Cereal A's "low fat" claim. The decision used the label, not the advertising, which is the mark of an informed consumer.

Solutions

Q1: Any four of: cost and budget; culture, religion and tradition; personal likes and dislikes; health and dietary needs; convenience and time; advertising and packaging; peer influence; and availability in the shops.
Q2: Any four of: the name of the food; the list of ingredients in order of weight; the net weight or volume; the manufacturer's or importer's name and address; storage instructions; the use-by or best-before date; and the nutrition information panel.
Q3: The per 100 g figures use the same amount of each product, so the comparison is fair; per serving figures can mislead because manufacturers choose different serving sizes to make their product look better.
Q4: "No added sugar" tells you no sugar was added during processing, but it does not tell you the food is sugar-free, because it may still contain natural sugars (for example from fruit), so you should still check the panel.
Q5: Any two of: using appealing images or attractive packaging; using celebrities or catchy slogans; offering special deals or free gifts; and using emotional messages such as fun, health or family to make the product seem more desirable.
