What this dot point is asking
This dot point asks you to identify and explain the many factors that drive what people eat, and to weigh the benefits of healthy eating against the real barriers that stop people acting on advice. Strong answers use specific examples and link an influence to an actual choice.
Factors that influence food selection
- Physical factors
- These include the availability and accessibility of food, where a person lives, their health and appetite, food skills, and the time available to cook. Someone in a remote town with one expensive supermarket faces different choices to someone near a fresh-food market.
- Social factors
- Family habits, friends, social occasions and the eating patterns of a community all shape choice. People often eat to fit in or to share an experience, and family traditions set lifelong food preferences.
- Cultural and religious factors
- Culture shapes which foods are familiar, celebrated or avoided. Religious rules may require or forbid certain foods, such as halal or kosher requirements, or fasting at particular times. Cultural identity is often expressed through food.
- Economic factors
- Income, the price of food and the cost of equipment or transport strongly affect choice. Healthier fresh foods can seem more expensive or less convenient than energy-dense packaged foods, especially for people on low incomes.
- Psychological factors
- Habit, emotion, comfort eating, beliefs, advertising and food marketing all influence selection. People may choose familiar comfort foods when stressed, or be swayed by branding, packaging and promotions.
Benefits of following healthy eating advice
Following healthy eating advice supports a healthy weight, provides the nutrients the body needs, gives steady energy, and reduces the long-term risk of diet-related chronic disease such as type 2 diabetes, heart disease and some cancers. It can also support mental wellbeing, concentration and physical performance.
Barriers to healthy eating
Even when people know what is healthy, real barriers get in the way:
- Cost: fresh and varied foods can be perceived as, or actually be, more expensive.
- Time and convenience: busy schedules push people towards fast or ready-made foods.
- Skills and knowledge: limited cooking confidence or nutrition knowledge.
- Access: living far from affordable fresh food (sometimes called a food desert).
- Marketing and environment: heavy advertising and easy availability of discretionary foods.
- Habit and taste: strong preferences for familiar, energy-dense foods.
When you answer, match the influence or barrier to the specific person or group in the question. For an adolescent, peer influence, marketing and convenience may dominate; for a low-income family, cost and access matter most; for an older person, food skills, appetite and mobility may be key. Showing that you can weigh benefits against barriers for a particular group, rather than listing factors in the abstract, is what lifts an answer to full marks.
Exam-style practice questions
Practice questions written in the style of VCAA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2025 VCAA4 marksA third-year university student lives in a four-bedroom shared house with a shared kitchen, a single microwave and a shared refrigerator, works part-time at a fast-food restaurant, and relies on fast food and ready-to-eat meals. Describe two examples of how living within a shared house could influence the student's food accessibility.Show worked answer →
Two marks for each of two distinct, well-described examples (the example plus its effect on accessibility).
Example 1 - limited storage and equipment. Sharing a single refrigerator and one microwave with several housemates limits the space the student has to store fresh food and the equipment available to prepare meals. With little fridge space and only a microwave, fresh ingredients are harder to keep, so the student is pushed towards shelf-stable, ready-to-eat or fast foods, reducing access to fresh, healthy options.
Example 2 - competition for kitchen time and shared resources. With all housemates sharing one kitchen, the student may struggle to access the cooking space at convenient times, especially around shifts. Limited or unpredictable access to the kitchen makes it harder to cook fresh meals, again increasing reliance on the convenience of fast food from work or ready-made supermarket meals.
Each example must clearly link the shared living arrangement to the student's ability to access food.
2025 VCAA3 marksA third-year university student lives in shared housing and relies on fast food and ready-to-eat meals. Analyse one way the social factor of education could influence the food choices of the students.Show worked answer →
Three marks for an analysis that connects education (a social factor) to a specific change in food choice.
Education refers to a person's level of nutrition knowledge and food literacy, often shaped by schooling and study. As university students, they are likely to have higher general education and access to reliable nutrition information, which can improve their understanding of healthy eating and food preparation.
This knowledge could influence their choices by helping them recognise that frequent fast food and ready-to-eat meals are high in saturated fat, salt and added sugar, prompting them to choose more nutritious options or cook simple balanced meals when time allows.
A full analysis also notes the limit: education raises awareness, but knowing what is healthy does not always change behaviour when barriers such as cost, convenience and limited kitchen access remain. Linking education to both the potential improvement and the gap between knowledge and action earns full marks.
2023 VCAA6 marksUsing an ethical shopping pyramid, analyse the influence of the social factors of income and accommodation on the purchase of an organic food box of fruit and vegetables.Show worked answer →
Six marks: roughly three for analysing income and three for analysing accommodation, each linked to whether the organic food box would be purchased.
Income. Organic produce and a regular organic food box are usually more expensive than conventional fruit and vegetables. A person on a higher income can more readily absorb this cost and prioritise ethically produced food, so they are more likely to subscribe. A person on a lower income faces competing demands on their money, so the higher price is a barrier and they are less likely to purchase the box even if they value organic food.
Accommodation. Accommodation affects storage, delivery access and stability of address. Someone with secure, spacious accommodation has refrigerator and storage space for a weekly box of fresh produce and a fixed address for delivery, making purchase practical. Someone in shared, temporary or small accommodation may lack storage space or a reliable delivery point, and may waste produce they cannot store, which discourages buying a food box.
A high-scoring answer analyses how each social factor either enables or restricts the purchase, rather than just describing income and accommodation in general.
