Food for Health is the first of the three areas of SQA National 5 Health and Food Technology. It develops your knowledge of the relationship between food, health and nutrition: what each nutrient does, how dietary needs change across life, what current dietary advice recommends, and how poor food choices lead to diet-related conditions. This page maps the area and shows how the parts connect.
The key topics in Food for Health
- Protein
- Functions (growth, repair, energy), sources, and the difference between high and low biological value protein.
- Carbohydrate
- Starch (slow-release energy), sugars (fast-release energy) and dietary fibre (NSP, for a healthy bowel), and the effects of too much sugar or too little fibre.
- Fats and oils
- Functions, the difference between saturated and unsaturated fat, the role of cholesterol, and the effects of too much fat.
- Vitamins
- The fat-soluble vitamins A and D and the water-soluble B group and vitamin C, their functions, sources and deficiency effects, and how cooking can destroy water-soluble vitamins.
- Minerals and water
- Calcium, iron, sodium and phosphorus, their functions, sources and deficiency or excess effects, and the functions of water.
- Dietary needs through life
- How needs change for babies and children, teenagers, adults, pregnant women and older adults, and how to adapt meals.
- Current dietary advice
- The Scottish Dietary Goals and the Eatwell Guide, and how to adapt food choices to follow them.
- Diet-related conditions
- Coronary heart disease, obesity, type 2 diabetes, dental caries, osteoporosis, anaemia, high blood pressure and bowel disorders, and the dietary changes that reduce risk.
How the topics connect
The nutrients underpin everything else. The vitamins and minerals often work in pairs (vitamin D helps absorb calcium; vitamin C helps absorb iron), and the same nutrient links to a life stage (calcium and bone growth in teenagers) and to a condition (too little calcium and osteoporosis). Current dietary advice is simply the practical summary of all the nutrient knowledge, and the diet-related conditions are what happens when that advice is ignored.
How to study Area 1
- Learn each nutrient as function, sources, too much, too little. Most marks follow this pattern, so a four-column note per nutrient is efficient.
- Link nutrients to life stages and conditions. The same fact (calcium builds bones) answers questions on teenagers, older adults and osteoporosis.
- Practise adapting meals. A large share of marks comes from improving a given meal to follow current dietary advice, so drill this skill.
- Use precise wording. National 5 rewards exact terms such as high biological value, saturated, cholesterol, haemoglobin and hypertension.
