Worked Solution & Example Answer:3.1 Answer the following questions on dysentery - NSC Consumer Studies - Question 3 - 2016 - Paper 1
Step 1
3.1.1 Name FIVE transmission possibilities of dysentery in the food environment.
Answer
- Contaminated Water: Dysentery can be transmitted through drinking or using contaminated water, which may come from unsafe sources.
- Food Contamination: Food that is washed or prepared with contaminated water can carry the bacteria.
- Flies: Flies that come into contact with feces can transfer pathogens to food items.
- Poor Hygiene Practices: Inadequate hygiene and sanitation practices, such as not washing hands before preparing or eating food, can lead to transmission.
- Direct Contact: It can also spread through direct contact with an infected person or their contaminated surfaces.
Step 2
3.1.2 Explain how dysentery can be treated.
Answer
Dysentery treatment focuses on hydration and replenishing lost fluids and electrolytes. Oral rehydration solutions are often essential for patients with severe symptoms. In some cases, antibiotics may be prescribed, especially when caused by bacterial infections like Shigella. Maintaining a nutritious diet during recovery aids in restoring health.
Step 3
3.2.1 Name THREE diet-related causes of high blood pressure.
Answer
- High Sodium Intake: Consuming excess salt can lead to fluid retention and increased blood pressure.
- Excessive Alcohol: High levels of alcohol consumption can elevate blood pressure.
- High Saturated Fat: Diets high in saturated fat can lead to weight gain and associated hypertension.
Step 4
3.2.2 The Heart and Stroke Foundation recommends regular testing of blood pressure. Write a paragraph to give reasons for this recommendation.
Answer
Regular blood pressure testing is crucial because high blood pressure often presents no symptoms, leading many individuals to remain unaware of their condition. By routinely checking their blood pressure, people can identify potential health issues early, assess risks of heart disease or stroke, and implement lifestyle changes necessary to manage their health effectively.
Step 5
3.3 Discuss the disorder that Ed's mother is concerned about.
Answer
Ed's mother is concerned about anorexia, a disorder characterized by the significant restriction of food intake, leading to severe weight loss. Those affected often have a distorted body image and may engage in excessive exercise to maintain or lose weight further, despite already being underweight. This concern is valid, as such eating behavior can have serious health consequences.
Step 6
3.4 Name THREE allergic reactions to the food additive tartrazine.
Answer
- Asthma: Tartrazine can trigger asthma attacks in sensitive individuals.
- Skin Rashes: An allergic reaction may manifest as skin rashes or hives upon consumption.
- Swelling: Some individuals may experience swelling, particularly in facial areas.
Step 7
Step 8
3.5.2 Explain why the fish cakes are not suitable for a person with gluten intolerance.
Answer
The fish cakes contain wheat flour in the crumbs, which is a source of gluten. For individuals with gluten intolerance or celiac disease, consuming gluten can lead to severe gastrointestinal distress and other health complications.
Step 9
3.5.3 Give reasons why some of the ingredients were irradiated (radiated).
Answer
Irradiation of certain ingredients, such as herbs and spices, is performed to eliminate harmful bacteria and pathogens, ensuring food safety and extending shelf life. This process helps prevent spoilage and maintains the quality of food products.
Step 10
Step 11
3.5.5 Discuss how the recommended cooking method for the fish cakes may be beneficial on obesity.
Answer
Baking fish cakes, rather than frying, means less added fat and calories, making them more suitable for weight management. This cooking method helps reduce overall energy intake, supporting weight loss or maintenance in individuals managing obesity.
Step 12
3.5.6 Evaluate the suitability of the fish cakes in the management of coronary heart disease.
Answer
The fish cakes are relatively low in saturated fat, which makes them a preferable choice for individuals managing coronary heart disease. Additionally, their omega-3 content can have heart-protective benefits, helping to lower cholesterol levels. However, due to their sodium content, portion control is essential to prevent excessive salt intake, which could counteract their benefits.
