What this dot point is asking
SEAB wants you to plan and adapt meals for people with special dietary needs: vegetarians, people with diabetes or high blood pressure, and people with food allergies or intolerances. The big idea is that the meal must still be balanced and appealing while meeting the special requirement, whether that is avoiding meat, limiting sugar or salt, or leaving out a food that causes harm. The marks come from a sensible swap or adaptation and a clear reason.
The answer
Vegetarians
A vegetarian does not eat meat (and a vegan eats no animal foods at all). The challenge is to keep enough good-quality protein, iron and (for vegans) calcium and vitamin B12. Adapt a meat dish by swapping the meat for a plant protein such as tofu, beans, lentils or chickpeas, using HBV soya or complementing two LBV foods. Add iron-rich vegetables with a vitamin C food to aid absorption.
People with diabetes
A person with diabetes must keep their blood sugar steady. Plan meals that are low in free sugar and use slow-release (complex) carbohydrate such as wholegrain rice, noodles or bread, with plenty of vegetables and fibre, lean protein, and fruit instead of sugary desserts. Choose water or unsweetened drinks.
People with high blood pressure
A person with high blood pressure should keep salt low. Plan meals using less salt in cooking, fewer salty processed foods (instant noodle seasoning, salted fish, heavy sauces), and more fresh ingredients and herbs and spices for flavour instead of salt.
Food allergies and intolerances
It is important to know the difference:
- A food allergy is a reaction by the body's immune system to a food. It can be severe or even life-threatening, for example a nut or shellfish allergy.
- A food intolerance is difficulty digesting a food, causing discomfort such as bloating, for example lactose intolerance. It is uncomfortable but not a dangerous immune reaction.
For both, the food must be left out and replaced. For lactose intolerance, swap cow's milk for soya, oat or lactose-free milk. For allergies, also prevent cross-contamination by using clean utensils and surfaces, preparing the safe dish separately, checking labels (including "may contain" warnings), and labelling dishes clearly.
Examples in context
Example 1. A vegetarian version of a local favourite. Turning mee goreng made with chicken and prawns into a vegetarian version with tofu, tempeh and extra vegetables keeps the dish familiar and tasty while supplying plant protein. The tofu and tempeh (both soya) give good-quality protein, showing how a meat dish is adapted for a vegetarian without losing nutrition.
Example 2. A diabetes-friendly economy rice plate. A person with diabetes choosing cai png can pick brown rice, two vegetable dishes and a steamed (not fried) protein, and drink plain water instead of a sweet drink. The wholegrain rice and vegetables give slow-release carbohydrate and fibre that help keep blood sugar steady, a practical adaptation using everyday food.
Try this
Q1. Suggest how to adapt a beef stir-fry so a vegetarian can eat it and still get enough protein. [2 marks]
- Cue. Replace the beef with tofu, tempeh or beans (plant protein), keeping good-quality or complementary protein in the dish.
Q2. Explain the difference between a food allergy and a food intolerance. [2 marks]
- Cue. Allergy = immune reaction, can be severe or life-threatening; intolerance = difficulty digesting a food, uncomfortable but not dangerous.
Q3. Suggest two precautions when preparing food for someone with a nut allergy. [2 marks]
- Cue. Any two of: avoid cross-contamination with clean utensils and separate preparation, check labels for nuts and "may contain" warnings, label dishes clearly.
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 marksA school is planning a buffet for a mixed group that includes a vegetarian, a student with a nut allergy, and a teacher with diabetes. (a) Explain one change to a chicken curry so the vegetarian can eat a similar dish and still get enough protein. (b) Explain two precautions to keep the food safe for the student with the nut allergy. (c) Suggest two choices that suit the teacher with diabetes. (Section C style)Show worked answer →
(a) Replace the chicken with a plant protein such as tofu, chickpeas or other beans to make a vegetable and tofu (or chickpea) curry, so the dish stays similar but provides HBV (tofu) or complementary plant protein instead of meat.
(b) Any two of: prepare and serve the nut-free dishes separately to avoid cross-contamination; use clean utensils and surfaces; check ingredient labels for nuts and "may contain nuts" warnings; and label dishes clearly so the student knows what is safe.
(c) Any two of: wholegrain rice or noodles instead of white (slow-release carbohydrate); plenty of vegetables; lean grilled or steamed protein rather than fried; fresh fruit instead of sugary desserts; and water or unsweetened drinks instead of sweet drinks.
What markers reward: a sensible protein swap that keeps the dish similar and nutritious, two genuine allergy precautions including cross-contamination, and two diabetes-friendly choices focused on lower sugar and slow-release carbohydrate.
Original4 marks(a) Explain the difference between a food allergy and a food intolerance. (b) Suggest one suitable food for a person who is lactose intolerant in place of cow's milk. (Section B style)Show worked answer →
(a) A food allergy is a reaction by the body's immune system to a food, which can be severe or even life-threatening (for example a nut allergy causing breathing difficulty). A food intolerance is when the body has difficulty digesting a food (for example lactose intolerance), causing discomfort such as bloating or stomach upset but not a dangerous immune reaction.
(b) Any one suitable alternative such as soya milk, oat milk, almond milk (if no nut allergy), or lactose-free milk.
What markers reward: a clear contrast between an immune reaction (allergy, potentially severe) and a digestion problem (intolerance, uncomfortable but not life-threatening), and one correct milk alternative.
