What social, cultural, economic and personal factors shape the food choices people make?
Explain the range of factors that influence food choice, including cultural, social, economic, psychological and environmental influences
Food choice is shaped by far more than nutrition: culture, family, cost, availability, marketing and personal preference all interact to determine what people actually eat.

What this dot point is asking
You need to identify the main factors influencing food choice, explain each with examples, and recognise that several factors usually act together.
Cultural and religious influences
Culture shapes which foods are considered normal, special or unacceptable, and how meals are prepared and shared. Religious rules guide food choice strongly: for example, some faiths avoid pork, others avoid beef, and some require fasting at certain times. Traditional and Aboriginal and Torres Strait Islander food practices, including the use of native foods (bush foods), are part of cultural identity and connection to Country, and are recognised in the Australian context.
Social influences
Social factors include family habits, peers and the occasion. Children learn eating patterns from family, and people often eat differently with friends, at celebrations or when eating out. Sharing food is central to many social events, so the company can matter as much as the food.
Economic influences
Cost and income strongly affect food choice. Cheaper, energy-dense foods can be more affordable than fresh produce, so lower income can limit access to a healthy diet. Availability also matters: people in remote areas may have less access to fresh, affordable food, an issue tied to food security in Topic 4.
Psychological and personal influences
Psychological factors include personal taste, appetite, mood and beliefs. People choose familiar flavours, may eat for comfort, and may follow ethical positions such as vegetarianism or concern for animal welfare. Sensory appeal (taste, smell, appearance and texture) is a powerful driver, sometimes outweighing nutrition.
Marketing and the food environment
Marketing and advertising influence choice, especially of discretionary foods, through packaging, branding, pricing deals and placement in stores. The wider food environment, including the availability of takeaway outlets and the convenience of processed foods, nudges choices. Health messages and food labelling also work in the other direction, helping people choose better.
Factors interact
In real life these influences combine. A person may want to follow the dietary guidelines (knowledge) but face a tight budget (economic), a long commute that favours convenience food (environment) and family traditions (cultural). Understanding this interaction explains why simply knowing what is healthy does not guarantee a healthy diet, and why improving population diets needs more than information.
In short, food choice is shaped by culture, religion, social settings, cost, availability, psychology, sensory appeal and marketing, which interact and often pull choices away from purely nutritional ideals. Recognising these influences explains real eating behaviour and the limits of nutrition education alone.
Exam-style practice questions
Practice questions written in the style of SACE Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2018 SACE Stage 22 marksMany members of society do not eat meat. Explain one physiological factor that prevents some individuals from eating meat.Show worked answer →
For 2 marks, name a physiological (body-based) factor and explain how it prevents meat consumption.
A clear example is a food allergy or intolerance: some people have an allergic reaction to a protein in meat (for example, a red-meat allergy linked to alpha-gal), causing symptoms such as swelling, hives or digestive upset, so they must avoid it (2 marks).
Other acceptable physiological factors include difficulty digesting meat, gout (where purines in red meat worsen the condition), or a medical condition that requires a low-meat diet. The key is that it is a bodily, not a belief-based, reason.
2018 SACE Stage 22 marksExplain one psychological reason why some individuals do not eat meat.Show worked answer →
For 2 marks, identify a psychological (mind/attitude-based) reason and explain it.
A common psychological reason is ethical or moral concern about animal welfare. Some people feel distress or strong disapproval at the idea of animals being killed for food, so they choose not to eat meat to align their diet with their personal values and beliefs (2 marks).
Other acceptable reasons include disgust at the taste, texture or appearance of meat, or anxiety about its health effects. The distinction from a physiological factor is that this is driven by feelings, attitudes or beliefs rather than the body's function.
