Worked Solution & Example Answer:Answer the following questions on cholesterol - NSC Consumer Studies - Question 3 - 2018 - Paper 1
Step 1
3.1.1 Name TWO types of cholesterol.
Answer
The two types of cholesterol are low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is often referred to as 'bad' cholesterol because it can lead to the buildup of plaques in arteries, while HDL is known as 'good' cholesterol as it helps remove cholesterol from the bloodstream.
Step 2
3.1.2 Explain the difference between the two types of cholesterol.
Answer
The primary difference between LDL and HDL lies in their function and impact on health. LDL cholesterol is responsible for transporting cholesterol to cells, but excessive levels can result in deposits in arteries, increasing the risk of heart disease. Conversely, HDL cholesterol works to remove excess cholesterol from the bloodstream, transporting it to the liver for disposal, thereby protecting against heart disease.
Step 3
3.2 Write a paragraph to discuss why genetically modified crops may save the world from starvation in the future.
Answer
Genetically modified crops have the potential to play a pivotal role in alleviating global hunger and ensuring food security. By enhancing crop resilience to adverse conditions such as droughts and pests, these crops can produce higher yields even in challenging environments. Additionally, GM crops can be engineered to have improved nutritional profiles, which is essential for combating malnutrition in vulnerable populations. Furthermore, their longer shelf-life helps reduce food waste, making food supplies more reliable in times of shortage. Overall, the adoption of genetically modified agriculture could significantly contribute to sustainable food systems.

3.3.3 Explain the function of sodium nitrite in this dish.
Answer
Sodium nitrite serves two primary functions in this dish:
- It acts as a preservative, extending the shelf life of the food by preventing spoilage from bacteria and other microorganisms.
- It enhances the flavor and color of the dish, making it more appealing to consumers.
Step 7
3.3.4 Explain why cow's milk, wheat, gluten and egg are separately listed on the label.
Answer
These ingredients are listed separately so consumers can easily identify potential allergens. This is crucial for individuals with allergies, as these components can cause severe reactions in sensitive individuals.

Step 9
3.3.6 Suggest TWO guidelines that must be followed by a consumer before eating this dish to prevent the transmission of food-borne diseases.
Answer
- Wash hands thoroughly before handling or preparing the dish to reduce the risk of contamination.
- Ensure the dish is heated to a high internal temperature before serving to kill any harmful bacteria.
Step 10
3.3.7 Explain why this dish is suitable for the management of osteoporosis.
Answer
This dish is suitable for managing osteoporosis primarily because it is high in calcium due to the presence of milk and cheddar cheese, which are essential for bone health. Furthermore, the vitamin D content in milk aids in the absorption of calcium, contributing to the maintenance of bone density and strength.

Step 12
3.3.9 Evaluate the suitability of this dish for a consumer who wants to manage obesity.
Answer
This dish is not well-suited for someone looking to manage obesity as it is high in energy content due to its carbohydrate and fat levels. The presence of high calories in both the pasta and the cheese could contribute to weight gain. Additionally, the fat content, particularly saturated fat, can be detrimental to weight management efforts.
