SACE Stage 2 Nutrition: complete 2026 guide to the topics and assessment

SACE Stage 2 Nutrition is the Year 12 nutrition course offered by the SACE Board of South Australia. It is a 20-credit contemporary science that links the biology of nutrients and digestion to real food choices, diet-related disease and the food systems that supply our food. Your final result combines school assessment (70 percent) with a single external electronic examination (30 percent).

This page is the index. Below you will find every dot-point answer we have for SACE Stage 2 Nutrition in 2026, organised by topic, alongside the structural notes you need to plan your study.

Please note: the exact focus-area headings and assessment weightings should be confirmed against the current SACE Board subject outline. The structure below reflects the standard organisation of the subject and the 70 percent school and 30 percent external split.

The topics in 2026

Principles of human nutrition

The scientific core: the macronutrients (carbohydrates, proteins and lipids) and their role in energy balance, the micronutrients (vitamins and minerals) and water, and how the digestive system breaks food down and absorbs nutrients.

Diet and health

How long-term dietary patterns affect health: the major diet-related diseases such as cardiovascular disease, type 2 diabetes, obesity and some cancers, and how the Australian Dietary Guidelines and food selection models support a balanced diet.

Food selection and society

Why people eat what they eat: the cultural, religious, social, economic, psychological and marketing influences on food choice, including Aboriginal and Torres Strait Islander food practices and food access.

Food production and sustainability

How food reaches us and at what cost: food security and sustainability, the factors affecting food supply, and the methods of food processing, preservation and food technologies that shape the quantity, quality and safety of food.

How SACE Stage 2 Nutrition is assessed in 2026

Your final subject result combines two parts:

School assessment (70 percent).

• Practical Investigations (30 percent). Designed or hands-on investigations into nutrition questions, reported within a set word or time limit, assessing how you plan, conduct, analyse and evaluate.
• Skills and Applications Tasks (40 percent). In-class tasks, commonly tests and supervised tasks, that assess how you apply nutrition understanding and analyse data, food labels and scenarios.

External examination (30 percent). A single electronic examination set and marked by the SACE Board, covering the whole subject and drawing on both scientific understanding and evaluation of issues.

School assessment is moderated by the SACE Board to keep standards consistent between schools. Confirm the exact assessment types and weightings against the current subject outline.

Our 2026 SACE Stage 2 Nutrition dot-point answers

Every link below is a focused answer to one part of the Nutrition subject outline. Each page identifies the concept, gives a worked answer, and flags the common mistakes.

Topic 1: Principles of Human Nutrition

• Macronutrients and energy
• Micronutrients and water
• Digestion and absorption
• Enzymes and chemical digestion
• The gut microbiome and health
• Malabsorption and food intolerance
• Nutrition through the life cycle
• Energy metabolism and BMR

Topic 2: Diet and Health

• Diet-related diseases
• Dietary guidelines and healthy eating
• Cardiovascular disease and diet
• Obesity and type 2 diabetes
• Food labels and nutrition information

Topic 3: Food Selection and Society

• Influences on food choice
• Aboriginal and Torres Strait Islander food and nutrition
• Global food and nutrition issues
• Food marketing and the media

Topic 4: Food Production and Sustainability

• Food security and sustainability
• Food production and supply
• Food processing and technologies
• Food safety, spoilage and preservation
• Genetic modification and emerging food technologies

How the topics connect

The topics build on one another. The principles of human nutrition explain what nutrients do inside the body; diet and health applies this to show how dietary patterns raise or lower disease risk; food selection and society explains why people make the choices that shape those patterns; and food production and sustainability looks at whether the food system can supply safe, nutritious food now and in the future. Energy balance, nutrients and diet-related disease recur throughout, so the scientific foundations pay off across the whole course.

How to use this hub

If you are starting the year: work through the principles of human nutrition first, since nutrients, digestion and energy balance underpin everything that follows.

If you are preparing a Practical Investigation: focus on planning a fair, valid investigation, controlling variables, and analysing and evaluating your data. Choose a dot point relevant to your topic and read it alongside your method.

If you are revising for the external examination: review the content topic by topic using the pages above, then practise applying it to unseen data, food labels and case studies, and prepare to evaluate social, cultural and environmental issues. Past SACE Board examination papers and exemplars are the best practice resource.
