What this dot point is asking
SEAB wants you to describe the main factors that affect food choice and explain how each influences what people eat. The big idea is that what ends up on a plate is shaped by far more than nutrition: money, culture, religion, health, convenience, taste and advertising all play a part. The marks come from naming genuine, separate factors and explaining, with examples, how each shapes what a person chooses.
The answer
Cost and income
Cost is a major factor. People on a tight budget choose affordable foods and may limit expensive items such as certain meats or imported produce. Income and food prices strongly shape the weekly shop.
Culture and religion
Culture affects the dishes people are used to and enjoy, while religion can require people to avoid or only eat certain foods:
- Muslims eat only halal food and do not eat pork.
- Many Hindus do not eat beef, and some follow a vegetarian diet.
- Festivals and traditions also shape what is eaten and when.
In multicultural Singapore, these influences sit side by side and widely affect food choice.
Health and special needs
Health leads people to choose foods that suit their condition or goals: a person with high blood pressure chooses low-salt foods, someone with diabetes limits sugar, and a person trying to lose weight chooses lower-fat, lower-sugar options. Allergies and intolerances also force certain choices.
Convenience and time
Convenience matters for busy people. Those with little time to cook may eat at hawker centres, buy ready-made or quick meals, or choose foods that are fast to prepare. This is a strong factor for working families and students.
Likes, dislikes and the senses
Personal likes and dislikes, shaped by taste, smell, appearance and texture, decide a lot. People naturally choose foods they find appetising and avoid those they dislike, whatever the nutrition.
Advertising, media and availability
Advertising and the media influence wants by making foods look appealing, while availability (what is sold locally and what is in season) limits or widens the options.
Examples in context
Example 1. Halal choices in a hawker centre. A Muslim family choosing food at a hawker centre looks for stalls with halal certification and avoids pork dishes, because their religion requires halal food. This shows religion directly shaping which stalls and dishes are chosen, a common everyday influence on food choice in Singapore.
Example 2. Convenience for a working couple. A busy working couple with little time to cook often buys dinner from a hawker centre or a ready-made meal on the way home. Convenience and time, rather than cost or nutrition, are the main factors here, showing how a busy lifestyle shapes what people eat.

Exam-style practice questions
Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Original8 marksDifferent people choose very different foods. (a) Describe four factors that affect a person's food choice. (b) For a busy working family in Singapore, explain how two of these factors might influence what they eat. (Section C style)Show worked answer →
(a) Any four of: cost and income; culture and religion (for example halal or vegetarian requirements); health and special dietary needs; convenience and time available; personal likes and dislikes; advertising and the media; and what is available locally or in season.
(b) For a busy working family, for example: convenience and time mean they may often eat at hawker centres or buy ready-made or quick meals because they have little time to cook; and cost means they choose affordable options and may limit expensive ingredients. (Other valid pairs accepted with sound reasoning.)
What markers reward: four genuine, distinct factors, and a sensible explanation of how two of them shape the food choices of a busy family, with reasons.
Original4 marks(a) Explain how religion can affect food choice, giving one example. (b) Explain how health can affect food choice, giving one example. (Section B style)Show worked answer →
(a) Religion can require people to avoid or only eat certain foods. For example, Muslims eat only halal food and do not eat pork, and many Hindus do not eat beef or follow a vegetarian diet. This shapes which foods they buy and eat.
(b) Health can lead people to choose foods that suit their condition or goals. For example, a person with high blood pressure chooses low-salt foods, or someone trying to lose weight chooses lower-fat, lower-sugar options and more vegetables.
What markers reward: a clear religious example that limits or directs food choice, and a clear health example where a condition or goal changes what a person chooses to eat.
