G2 Nutrition and Food Science in the 2027 Singapore–Cambridge Secondary Education Certificate (SEC) is subject K235. It combines an 80-mark written paper worth 40% and a 60-mark supervised coursework assignment worth 60%. Students learn how nutrition, practical food preparation, food safety and informed consumer choices fit together.
This is not simply a cooking examination. The syllabus asks students to explain nutrients, read food labels, plan meals for an intended group, investigate ingredient behaviour and evaluate the dishes they prepare. A tasty recipe is not enough if it cannot be justified using the task’s nutritional needs, research and evidence. The most valuable habit is to ask why this choice suits this person and this situation.
This guide uses the SEAB 2027 G2 Nutrition and Food Science K235 syllabus and 2027 G2 school-candidate directory. The older reference code was 6073. The syllabus includes coursework assessed during the examination year; follow your school’s actual assignment, timetable, food-safety and supervision rules. Any sample meal discussed here is an illustration, not a clinical nutrition prescription or an official examination solution.

2027 SEC K235 paper structure and weighting
| Assessment | Description | Marks | Weight |
|---|---|---|---|
| Paper 1: Written examination | 1 hour 30 minutes; all questions compulsory | 80 | 40% |
| Section A of Paper 1 | Multiple-choice questions | 16 | Within Paper 1 |
| Section B of Paper 1 | Short-answer and data-response questions | 40 | Within Paper 1 |
| Section C of Paper 1 | Open-ended questions | 24 | Within Paper 1 |
| Paper 2: Coursework | Teacher-supervised research, food investigation, practical preparation and evaluation | 60 | 60% |
In Paper 1, the student must handle more than factual recall: interpreting data and giving relevant explanations are important. Paper 2 carries the greater weight and is assessed through a longer inquiry-and-making process. Studying only written theory while leaving coursework planning until the last moment is therefore a poor strategy.
SEAB states that the coursework assignment is issued at the beginning of the examination year and is completed for assessment by the end of July or early August. The school must allocate 25 hours of curriculum time to discussing, facilitating and carrying out the investigation and practical work. Those 25 hours are an official allocated curriculum requirement, not a promise that the entire preparation can be completed unsupervised at home.
The examination tests three connected abilities
The assessment objectives concern knowledge with understanding; handling information and solving problems; and applying knowledge and skills in different contexts. The overall indicative weights are 35%, 25% and 40% respectively. A learner needs to know why a food contains particular nutrients, how that information is interpreted and whether a resulting dish meets the stated purpose.
For example, a student may correctly identify protein-rich ingredients but fail to justify why a selected dish suits the assignment’s target group. The missing operation is the connection between nutritional knowledge, research and the practical choice.
Nutrition and health: start with what nutrients do
The syllabus covers nutrients, water and dietary fibre
Candidates study proteins, carbohydrates, fats, vitamins, minerals, water and dietary fibre. The aim is not merely to memorise a list of foods. Students need to explain the functions of nutrients in the body, sources in the diet and how intake relates to individual needs. The 2027 syllabus also specifies relevant terms such as essential amino acids, types of carbohydrates and kinds of dietary fat.
Protein is needed for growth and repair, among other functions. Carbohydrates provide a major energy source. Fat has important roles but varies in type and food context. Vitamins and minerals perform diverse functions; ‘all vitamins give energy’ is not a scientifically accurate general explanation. Water and dietary fibre should not be treated as optional afterthoughts.
An useful learning exercise is to take an ordinary lunch and identify different components: which items contribute carbohydrate, which supply protein, where do fibre and micronutrients appear, and how does preparation change the final meal? This encourages explanation rather than treating foods as morally ‘good’ or ‘bad’.
Understand nutritional distinctions without oversimplifying
The syllabus distinguishes monosaccharides, disaccharides and polysaccharides, categories of fats, fat- and water-soluble vitamins, and sources of selected minerals. Students should learn each category in the level of detail the syllabus asks for. A clear example is often more useful than a complicated general claim.
For instance, dietary fibre is associated with foods such as vegetables, fruits, legumes and wholegrains. It is not identical to digestible carbohydrate that provides energy. Explaining these differences helps students interpret recipes and packaging without relying on advertising slogans.
Diet and health: explain risk, not diagnosis
K235 covers malnutrition in the sense of insufficient or excessive nutrient intake and health problems associated with diet, water and dietary fibre. Examples in the syllabus include obesity, hypertension, type 2 diabetes, coronary heart disease, dehydration, heat stroke, constipation, osteoporosis and anaemia.
For an examination explanation, describe an appropriate relationship between intake and the specified health issue. Do not claim that an individual has a disease merely because a food diary shows one dietary pattern. Diagnosis and personal dietary treatment belong to qualified healthcare professionals, not a student’s practice worksheet.
Avoid extreme food rules. A child preparing for an examination needs a sound understanding of nutrition, not a restrictive diet based on fear. The purpose of K235 is food literacy, not encouraging students to label themselves or classmates based on body size.
Food literacy: plan for a person, budget and context
Meal planning depends on the intended group
The syllabus asks students to consider nutritional needs at different life stages, including school children, teenagers, adults and older people. It also covers factors such as age, activity, health status, preferences, cultural traditions, religious practices, cost and convenience. A meal that suits one person may not suit another without changes.
If a coursework assignment is about older adults, a response should consider the specific needs and conditions described in the task. If it concerns teenagers, examine the given activity and nutritional context. Do not invent an allergy, health condition or dietary requirement merely to make a response sound more scientific.
Use Singapore’s My Healthy Plate as a guide, not a rigid prescription
The Health Promotion Board’s My Healthy Plate uses a simple visual guide for balanced meals: approximately one-quarter wholegrains, one-quarter protein-rich foods and one-half fruit and vegetables. The proportions communicate a helpful general pattern; actual needs, meal composition and medical requirements vary.
In a Singapore meal-planning exercise, a student might compare a rice-and-side-dishes meal with a second meal of noodles and other ingredients. Rather than declaring one automatically healthier, describe food groups, portions, preparation methods and the supplied target group. Consider whether a realistic modification could improve balance without wasting food or ignoring cultural preferences.
Food labels are evidence, but must be read carefully
K235 includes convenience foods and the information on food and nutrition labels. Students should distinguish per-serving values from per-100-gram values, check the stated serving size and compare like with like. A product that has fewer grams of a nutrient per serving may simply have a smaller labelled serving.
Imagine Product A gives 8 g of a nutrient per 100 g and Product B gives 6 g per 100 g. A direct comparison on that stated basis is straightforward. However, one serving may be larger than another, and the choice may also depend on other nutrients, price or convenience. Explain the comparison basis before making a recommendation.
Convenience food can have real advantages and limitations
Ready-to-cook and ready-to-eat foods can save time and improve accessibility in busy situations. Yet products vary in nutrition, packaging, cost, storage needs and preparation requirements. An evidence-based answer considers the actual product and user rather than asserting that all packaged food is unsuitable.
Smart consumer choices also require reading ingredients and handling instructions. A food can be convenient while still needing safe refrigeration or thorough cooking under the manufacturer’s directions. Students should treat food safety and nutritional adequacy as different questions.
Food science: cooking is a controlled transformation
Food safety comes before a polished presentation
The syllabus includes avoiding food spoilage and contamination during preparation, cooking and storage. Good practices include suitable hygiene, separation of raw and ready-to-eat items, appropriate storage and safe food handling under school guidance. Recipes and assessment plans should allow sufficient time to do these correctly.
Students should not undertake risky food preparation to simulate an unfamiliar practical task without an appropriate supervisor. Food allergies, equipment rules and storage requirements must be addressed according to school procedures and any relevant food-safety guidance.
Different ingredients behave differently in cooking
The syllabus includes the choice, nutritional characteristics and preparation effects of meat, poultry, seafood, eggs, dairy products, cereals and other food ingredients. Some cooking methods change texture, moisture, colour and sensory qualities. The learner should connect a physical observation to a relevant food-science explanation.
Suppose two small batches of a food mixture use different amounts of a binding ingredient while the remaining conditions are controlled. The resulting texture can be compared through a defined sensory observation. The scientific question is not simply ‘Which is nicer?’ but ‘What changed, how was it observed, and what does the evidence suggest about the ingredient’s function?’
An exploratory study needs a useful variable
Coursework asks students to plan and conduct an exploratory study informed by research. A good investigation changes a specified factor and makes relevant observations while keeping other important conditions comparable. If multiple conditions change at once, the result may be difficult to interpret.
A fictional study might compare the texture of a product when one ingredient amount changes under the same appropriate cooking conditions. Record the actual result in sensory terms, such as firmness or moisture perception, rather than writing ‘nice’ for every sample. Then explain which version better suits the target group and why.
Sensory evaluation is more than liking the food
Sensory evaluation involves qualities such as appearance, aroma, taste, texture and relevant eating experience. The specific terms used should match the food and the coursework brief. A precise observation such as ‘the centre remained softer than the outer surface’ conveys more than ‘the dish was delicious’.
Honest evaluation also identifies what did not work. If a dish was too dry or difficult to portion, that may indicate a need to adjust the cooking method or serving design. Inventing perfect outcomes defeats the purpose of investigation and could undermine the integrity of assessed work.
Paper 2 coursework: how the 60 marks are earned
| Assessment criterion | Marks | What students should demonstrate |
|---|---|---|
| Research | 6 | Relevant information organised to address the task |
| Decision Making | 6 | Selection and justified suitability of final dishes |
| Exploratory Study: Plan and Conduct | 6 | A deliberate test with suitable methods |
| Exploratory Study: Discussion | 6 | Interpretation of real observations |
| Planning | 6 | Recipes, equipment, ingredients and a practical time plan |
| Execution: Organisation and Management | 6 | Independent and efficient practical organisation |
| Execution: Manipulation | 10 | Appropriate food-preparation and cooking skills |
| Execution: Product and Presentation | 8 | Suitable dishes and clear photographic evidence |
| Evaluation | 6 | Sensory evaluation and thoughtful review of the work |
The coursework requires the selection and preparation of three final dishes appropriate to the assignment. Planning must connect the choice with earlier research. The student also develops an exploratory study, records observations, prepares the final dishes under the required supervision and evaluates the outcome.
The report is word-processed and submitted electronically. SEAB specifies 15–20 numbered pages, with photographs of the exploratory study and final dishes. The recommended typeface is Arial at a minimum 11-point size or Times New Roman at a minimum 12-point size. These are official presentation requirements, so students should not depend on an unofficial template that conflicts with them.
Research should lead to decisions
A long collection of recipes from the internet is not meaningful research unless it helps answer the brief. For each source, ask what the student learned and how that changed the choice of dish, ingredient, method or portion. Record relevant references appropriately and use the school’s citation instructions.
A report could explain that a target group needs meals easy to prepare within a specified time, and then compare which recipes satisfy that constraint while meeting nutritional considerations. The actual target group and constraints must come from the given coursework assignment.
Planning must anticipate the practical session
The student should identify ingredients, quantities, equipment, preparation sequence and the time needed for each activity. Practical planning is not only a timetable. It reduces the risk of unfinished food, unsafe work or missed documentation.
A well-sequenced plan can account for tasks that happen in parallel where safe and appropriate. The quality of the plan should be judged by whether it is usable in the actual supervised kitchen, not by how decorative the table appears.
Authenticity and school supervision are essential
Coursework is an examination component, not a take-home essay for someone else to write. Parents and tutors may help the learner understand concepts and practise independently, but must not manufacture research findings, write the assessed report as their own or prepare the assessed final dishes for the student.
When the child is unsure how much assistance is permitted, ask the coursework teacher. It is always safer to clarify before acting than to risk submitting work that no longer reflects the student’s own effort.
Common mistakes and targeted repair
| Problem | Why it matters | Better next action |
|---|---|---|
| Only memorising nutrient definitions | The learner cannot apply them to meal choices | Explain an actual target-group scenario |
| Comparing different food-label serving bases | The numerical conclusion is misleading | Standardise the comparison first |
| A research section with no connection to dishes | The selection is unjustified | Link each finding to a design choice |
| Changing several experiment conditions | The effect of one ingredient cannot be isolated | Control the relevant variables |
| Sensory evaluation says only ‘nice’ | Observations are uninformative | Use specific appearance, aroma or texture terms |
| Preparing the report at the last minute | Photographs and process evidence may be missing | Keep dated, authentic records within school rules |
| Unsafe handling or incomplete preparation plans | The task may be compromised | Follow supervised hygiene and time procedures |
An illustrative small-group theory lesson
- Retrieve two nutrition facts and one food-safety principle.
- Inspect a real marked short-answer or data-response question.
- Identify whether the child missed a nutrient concept, label comparison or causal explanation.
- Model the missing reasoning using an unfamiliar food label.
- Have the student independently justify one suitable meal modification.
- Close with a focused correction and next practice task.
This sequence adapts the diagnosis and independent-transfer method demonstrated in eduKateSG’s Clementi three-pupil teaching reference. It is a general approach to theory teaching, not confirmation of a current K235 tuition class or authorisation to assist in assessed coursework.
Four-week preparation cycle alongside the actual coursework
| Week | Written-paper focus | Coursework awareness | Evidence of improvement |
|---|---|---|---|
| 1 — Diagnose | Nutrients, meal planning and food label tasks | Check school assignment requirements and milestones | Identify two recurring misconceptions |
| 2 — Repair | Explain health-related concepts and safe food processes | Review the suitability of genuine research and planning | Student can explain decisions without a model |
| 3 — Apply | Interpret unfamiliar nutrition data and an open-ended scenario | Check that student observations are accurately recorded | Reasons match evidence and target-group needs |
| 4 — Integrate | 90-minute Paper 1 practice and targeted corrections | Review school feedback and upcoming official deadlines | Fewer repeat errors and a realistic next cycle |
This plan is not a replacement for the 25 hours of supervised school curriculum time or the school’s formal coursework schedule. A four-week revision cycle can be repeated while coursework proceeds according to the examination-year timeline. No particular grade is guaranteed.
Frequently asked questions
What is the 2027 SEC G2 Nutrition and Food Science code?
K235. SEAB lists 6073 as the earlier reference code.
How much is written examination and how much is coursework?
Paper 1 is 40% and Paper 2 coursework is 60% of the combined subject result.
How long is the written paper?
One hour 30 minutes. It is worth 80 marks, with 16 marks of MCQs, 40 of short-answer and data-response questions, and 24 of open-ended questions.
What does coursework involve?
An assigned, supervised investigation and practical project involving research, decisions, an exploratory study, planning, execution and evaluation of three dishes.
When is coursework completed?
The assignment is issued at the beginning of the examination year. The syllabus indicates assessment completion by late July or early August, with 25 hours of allocated curriculum time under teacher supervision.
How long is the coursework report?
The report must be 15–20 numbered pages, word-processed and submitted electronically with relevant photographic evidence.
Do students have to cook for a particular target group?
The assignment specifies the task context. Students should justify dishes according to the actual target group and research findings rather than assume the same menu is suitable for everyone.
Is the subject only about nutrition?
No. It includes nutrition and health, food literacy, consumer choices, food science, practical preparation and evaluation.
May parents create the coursework report to help the student?
No. The assessed work should authentically reflect the candidate’s own supervised investigation and practical work. Ask the school teacher about permitted support.
Can a student prepare independently for Paper 1?
Yes, through official syllabus review, school feedback, practice questions and appropriate learning resources. Coursework must still follow the required school supervision.

A useful action for students and parents
Choose one food label and one example meal from the learner’s notes. Ask what the numbers mean, whose needs the meal is meant to meet and what evidence supports a modification. For coursework, ask the student to explain why an ingredient or dish was selected without writing the assessed answer for them. Strong food science is thoughtful and testable, not a collection of favourite recipes.
