Commonly confused
Pairs that lose marks when they are blurred together.
Isotonic drink vs Hypotonic drink
Isotonic drink: a fluid with a concentration equal to body fluids. Hypotonic drink: a fluid more dilute than body fluids.
High GI food vs Low GI food
High GI food: a food that raises blood glucose quickly. Low GI food: a food that raises blood glucose slowly.
Carbohydrate vs Protein
Carbohydrate: the main fuel for moderate and high-intensity exercise. Protein: the nutrient used mainly to build and repair muscle.
Questions from this topic
Each one with the model answer underneath.
- 1
What is a balanced diet?
Model answer
A balanced diet contains the right amounts of each nutrient for health and activity. A balanced diet includes carbohydrate, fat, protein, vitamins, minerals, fibre and water.
- 2
What are the relative proportions of carbohydrate, fat and protein in a balanced diet?
Model answer
About 55% of energy should come from carbohydrate and about 30% from fat. About 15% should come from protein.
- 3
What is energy balance?
Model answer
Energy balance is when energy intake equals energy expenditure. Body mass then stays the same.
- 4
What happens when energy intake exceeds expenditure?
Model answer
The extra energy is stored as fat. Body mass increases.
- 5
What happens when energy expenditure exceeds intake?
Model answer
The body uses stored energy. Body mass decreases.
- 6
How is energy in food measured?
Model answer
Energy is measured in kilojoules or kilocalories. One kilocalorie is about 4.18 kilojoules.
