Name: _________________________ Class/Set: ____________ Date: ____________

Q1: Which group of nutrients is primarily responsible for the growth and repair of muscle tissue and cells within the human body?

a) ☐ Carbohydrates b) ☐ Proteins c) ☐ Fats d) ☐ Fibre

⇨ Study the table below showing the nutritional content of four different snack items per 100g.

Snack Item	Sugar (g)	Salt (g)	Saturated Fat (g)
Apple	10.0	0.01	0.0
Crisps	0.5	1.50	3.5
Chocolate Bar	55.0	0.20	18.0
Plain Rice Cake	0.1	0.05	0.1

Q2: Based on the table provided, which snack would be the most suitable choice for a student specifically trying to reduce their intake of saturated fats and added sugars?

a) ☐ Apple b) ☐ Crisps c) ☐ Chocolate Bar d) ☐ Plain Rice Cake

Q3: Regular physical exercise has a significant impact on the human circulatory system. What is the most accurate description of how the heart adapts to long-term exercise?

a) ☐ The heart beats faster when resting to ensure more oxygen reaches the brain. b) ☐ The heart muscle becomes weaker because it is being overworked. c) ☐ The heart muscle becomes stronger and more efficient at pumping blood around the body. d) ☐ The heart stops pumping blood to the digestive system to save energy for the legs.

Q4: In a balanced diet, which mineral is essential for the development of strong bones and teeth, and which food group is a primary source of it?

a) ☐ Iron, found mainly in citrus fruits like oranges. b) ☐ Calcium, found mainly in dairy products like milk and cheese. c) ☐ Sodium, found mainly in leafy green vegetables like spinach. d) ☐ Potassium, found mainly in red meats like beef.

Q5: Why is it important to include a sufficient amount of water and fibre in a daily diet for the maintenance of a healthy body?

a) ☐ Water provides the body with its main source of energy, while fibre builds muscle. b) ☐ Water helps transport nutrients and oxygen in the blood, while fibre aids the digestive system in moving waste. c) ☐ Water and fibre are both used by the body to produce Vitamin C. d) ☐ Water makes the bones stronger, while fibre prevents the heart from beating too quickly.

⚠ TEACHER’S GUIDANCE

💡 Pedagogical Landing (HUD)

• Year Group Focus: This resource is calibrated for Year 6. It bridges the gap between basic food group identification and the more complex understanding of physiological impacts (e.g., circulatory efficiency and cellular repair) required for KS3 transition.
• 🧠 Pedagogical Pulse: Watch for students who confuse 'Carbohydrates' and 'Proteins'. Many children associate 'energy' with all food; explicitly teaching that carbohydrates are the primary fuel source while proteins are 'building blocks' is a key Year 6 milestone.
• 🔍 Data Literacy: Q2 requires students to synthesise three different variables (Sugar, Salt, Fat). Encourage students to use a process of elimination by checking one column at a time.
• ⚠ Safety & Nuance Check: When discussing diet and health, maintain a neutral and supportive tone. Avoid labelling foods as 'good' or 'bad'—instead, use the terminology of 'balance', 'frequency', and 'nutritional density' to support positive relationships with food.

Answer Key & Explanations

Q1: b

Explanation: Proteins are essential for growth and repair. While carbohydrates provide energy and fats provide insulation/stored energy, only proteins provide the amino acids necessary to rebuild tissues.

Q2: d

Explanation: The Plain Rice Cake has the lowest combined values for sugar (0.1g) and saturated fat (0.1g). While the apple is healthy, it contains 10.0g of natural sugar, making the rice cake the 'most suitable' choice for the specific criteria of the question.

Q3: c

Explanation: The heart is a muscle. Like any other muscle, exercise makes it stronger and more efficient. This means it can pump a larger volume of blood with fewer beats, often leading to a lower resting heart rate in fit individuals.

Q4: b

Explanation: Calcium is the mineral responsible for bone density and tooth enamel. Dairy is the most well-known source, though it can also be found in fortified cereals and some green vegetables. Iron is used for blood (haemoglobin), not bones.

Q5: b

Explanation: This question tests the understanding of bodily functions. Water is the primary component of blood plasma, used for transport. Fibre cannot be digested by humans, but its bulk is necessary to help the muscular walls of the intestines move food through the system (peristalsis).
