Section 1 Quiz

1. What are the two main forms of carbohydrates?

A. Saturated and unsaturated
B. Simple and complex
C. Soluble and insoluble
D. Complete and incomplete

A is incorrect

A is incorrect because saturated and unsaturated are types of fats, not carbohydrates. Hint: Look for terms that describe the rate at which energy is released.

B is correct

Correct!

C is incorrect

C is incorrect because soluble and insoluble refer to types of fibre, not the primary forms of carbohydrates. Hint: The correct options are associated with energy release and blood sugar levels.

D is incorrect

D is incorrect because complete and incomplete describe proteins based on their amino acid content, not carbohydrates. Hint: The correct options differentiate between quick and slow energy sources.

2. What is fibre recognised for in terms of health benefits?

A. Maintaining digestive health and disease prevention
B. Increasing HDL cholesterol levels
C. Lowering LDL cholesterol levels
D. Providing all nine essential amino acids

A is correct

Correct!

B is incorrect

B is incorrect because increasing HDL cholesterol levels is also a benefit of unsaturated fats, not fibre. Hint: Focus on the specific system in the body that fibre benefits.

C is incorrect

C is incorrect because lowering LDL cholesterol levels is a benefit of unsaturated fats, not fibre. Hint: Think about the digestive system.

D is incorrect

D is incorrect because providing all nine essential amino acids is a characteristic of complete proteins, not fibre. Hint: The correct answer relates to a type of carbohydrate that the body cannot digest.

3. Which of these is a source of complete proteins?

A. Whole grains
B. Legumes 
C. Nuts and seeds
D. Meat, fish, eggs, and dairy

A is incorrect

A is incorrect because whole grains typically provide incomplete proteins, lacking some essential amino acids. Hint: Look for sources that contain all nine essential amino acids.

B is incorrect

B is incorrect because legumes are usually plant-based and may not provide all essential amino acids. Hint: Complete proteins are typically found in a different food group.

C is incorrect

C is incorrect because nuts and seeds may not have all nine essential amino acids by themselves. Hint: The correct answer includes animal-based food items.

D is correct

Correct!

4. What percentage of energy should come from carbohydrates according to the Reference Intake (RI) for adults in the UK? 

A. Less than 35%
B. 15-20% 
C. 50%
D. 70%

A is incorrect

A is incorrect because less than 35% is the suggested RI percentage for fat intake, not carbohydrates. Hint: Look for the macronutrient that is the body's primary energy source.

B is incorrect

B is incorrect because 15-20% is the suggested RI percentage for protein intake, not carbohydrates. Hint: Carbohydrates should make up the majority of energy intake according to the RI. 

C is correct

Correct!

D is incorrect

D is incorrect because 70% is too high compared to the RI guidelines for carbohydrate intake. Hint: The correct answer is the balanced middle-ground percentage for energy.
