CCEA A-Level Nutrition and Food Science: complete guide to the units, the AS and A2 exams and how to study each topic
A complete guide to CCEA A-Level Nutrition and Food Science (specification 2016). Covers the principles of nutrition, diet, lifestyle and health, food security, safety and quality, and the research project, how the AS and A2 units are structured and assessed, and how to study each unit for top grades.
CCEA A-Level Nutrition and Food Science (specification first taught 2016) is a two-year course split into AS and A2, set and marked by CCEA in Northern Ireland. It studies the science of nutrition, the link between diet and health, the security, safety and quality of the food supply, and independent research. This page is the index: below is a map of the four units, the assessment structure, and how to study each unit.
The CCEA Nutrition and Food Science units
The specification groups the subject content into four units across the AS and A2.
- Principles of Nutrition (Unit AS 1)
- The foundation. It covers the macronutrients (protein, fats and lipids, and carbohydrates including dietary fibre), the micronutrients (vitamins and minerals) and water, energy balance and the Dietary Reference Values, and nutritional needs through the life stages. The unifying idea is that the body needs the right balance of nutrients, which changes through life.
- Diet, Lifestyle and Health (Unit AS 2)
- The applied-health unit. It covers current dietary guidelines and government strategy, the diet-related diseases (obesity, coronary heart disease, type 2 diabetes, diet and cancer, and bone, dental and blood conditions), and the functional properties of nutrients in food. The unifying idea is that diet and lifestyle protect or harm health.
- Food Security, Safety and Quality (Unit A2 1)
- The synoptic unit, offered as Option A Food Security and Sustainability or Option B Food Safety and Quality. It covers food choice, food security and sustainability, provenance and traceability, the microbiology of spoilage and poisoning, food hygiene and HACCP, preservation and processing, and food quality, additives and labelling. The unifying idea is securing a safe, sustainable food supply from producer to consumer.
- Research Project (Unit A2 2)
- The internally assessed coursework. Students plan and carry out an independent investigation, using primary and secondary data, and present a structured report. The unifying idea is applying research skills to a real nutrition or food-science question.
Assessment structure
CCEA A-Level Nutrition and Food Science is split between AS (40 percent) and A2 (60 percent), with three written units and one internally assessed project.
- AS 1 Principles of Nutrition - a written paper on macronutrients, micronutrients, water, energy and life-stage needs.
- AS 2 Diet, Lifestyle and Health - a written paper on dietary guidelines, diet-related disease and the functional properties of nutrients.
- A2 1 Food Security, Safety and Quality - a synoptic written paper taken as Option A (Food Security and Sustainability) or Option B (Food Safety and Quality).
- A2 2 Research Project - an internally assessed, externally moderated independent investigation.
How to study CCEA Nutrition and Food Science
The subject rewards precise nutritional knowledge, clear disease and food-science explanations, and balanced evaluation.
- Work from the specification statements. Each point is a checklist; questions are written from them.
- Learn each nutrient fully. Structure, function, sources, and the effects of deficiency and excess, plus the key recommendations and energy values.
- Learn each disease as a chain. Cause, mechanism, consequence and dietary advice, noticing how the healthy-diet messages overlap.
- Master the food science and safety. The functional properties, the microbiology and conditions for growth, hygiene and HACCP, and preservation and labelling.
- Prepare the research project carefully. Practise forming a focused question, planning an ethical method, and analysing primary and secondary data.

Each unit has a specification-level overview with worked questions and cross-links, plus dot-point pages and a quiz. Browse the full set at /ccea-a-level/nutrition-and-food-science/syllabus.
For the official specification
CCEA publishes the full specification, past papers and mark schemes at ccea.org.uk. Always revise from the current CCEA specification and CCEA's own past papers, because the unit titles, the A2 1 option structure and the research-project expectations are board-specific.
