Food, nutrition and health is the foundation of SQA Higher Health and Food Technology. It covers what nutrients do, how dietary needs change across life, and how diet causes or prevents disease - knowledge you then apply to consumer choice, functional properties and product development. This page maps the key areas and shows how they connect.
The key areas
- Macronutrients and energy
- Protein builds and repairs tissue and varies in biological value; fats and oils give concentrated energy and carry fat-soluble vitamins; carbohydrates (starch, sugars, NSP) are the main energy source. Food supplies energy, and energy balance decides body weight.
- Vitamins, minerals and water
- Micronutrients are needed in small amounts but are essential - fat-soluble vitamins A, D and E; water-soluble B group and C; folic acid; the minerals calcium, iron, sodium, phosphorus and fluoride; and water. Each has a function, sources and a deficiency (or excess) effect.
- Dietary advice and needs
- Current advice (the Scottish Dietary Goals and the Eatwell balance) sets the benchmark, and dietary needs shift across life stages - pregnancy, babies, children, teenagers, adults and the elderly - and for vegetarians and vegans.
- Diet-related diseases
- Diet causes or prevents obesity, coronary heart disease, type 2 diabetes, dental caries, bowel disorders, osteoporosis, anaemia and hypertension. Each links a dietary cause to a mechanism and to the changes that reduce the risk.
How this strand connects to the rest of the course
Nutrition is not learned for its own sake. It feeds straight into the other strands:
- Contemporary food issues - dietary advice explains why labels carry nutrition information and why manufacturers reformulate to cut fat, sugar and salt.
- Functional properties - the same fats, proteins and carbohydrates that matter for health also give food its structure and texture.
- Food product development - matching a product to a target group's dietary needs is a core development skill.
How to study this strand
- Learn nutrient by nutrient. For each nutrient, fix its function, two or three sources, and its deficiency or excess effect - this is the spine of most questions.
- Master the "partner" relationships. Vitamin D and calcium, vitamin C and iron, saturated fat and cholesterol - these links are favourite Higher questions.
- Always justify. Higher rewards explaining why a group or change matters, not just listing it.
- Practise the mechanisms. Be able to write the disease chains (for example saturated fat to LDL cholesterol to atheroma to narrowed arteries).
- Use SQA past papers. Question-paper items are written directly from these key areas, so the SQA's wording is the best guide to depth.
