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: Drinking or using water that has been contaminated with feces.
- Food Contamination: Consuming food that has been prepared with contaminated hands.
- Insects: Flies and other insects that carry the bacteria can contaminate food by landing on it.
- Poor Hygiene: Inadequate washing of fruits and vegetables before consumption.
- Close Contact: Exposure through direct contact with infected individuals or surfaces.
Step 2
3.1.2 Explain how dysentery can be treated.
Answer
Dysentery treatment primarily focuses on preventing dehydration. Oral rehydration solutions (ORS) are crucial to replace lost fluids and electrolytes. In cases caused by bacterial infections, antibiotics may be prescribed. For amoebic dysentery, specific medications targeting the amoeba may be necessary. Supportive care and maintaining proper hydration are essential components of effective treatment.
Step 3
3.2.1 Name THREE diet-related causes of high blood pressure.
Answer
- Excessive Salt Intake: High sodium consumption can lead to increased blood pressure.
- High Fat Diets: Diets rich in saturated fats may contribute to weight gain and heart diseases, indirectly affecting blood pressure.
- Low Fruit and Vegetable Intake: Insufficient consumption of potassium-rich foods can exacerbate 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 testing of blood pressure is critical because high blood pressure often goes unnoticed due to the lack of symptoms, making it a 'silent killer.' Early detection allows individuals to manage their health more effectively and can prevent severe complications such as heart attacks or strokes. By monitoring blood pressure, individuals can make necessary lifestyle changes and seek medical intervention when required, reducing the risk of long-term health issues.
Step 5
3.3 Discuss the disorder that Ed's mother is concerned about.
Answer
Ed's mother is concerned about anorexia, an eating disorder characterized by an intense fear of gaining weight and a distorted body image. Individuals with anorexia often restrict their food intake drastically, leading to significant weight loss and malnutrition. Symptoms may include excessive exercise and an obsession with food, dieting, and body size. This condition can have severe health implications, including heart problems, weakened bones, and in extreme cases, it can be life-threatening. Therefore, it is essential to address these concerns with professional help and support.
Step 6
3.4 Name THREE allergic reactions to the food additive tartrazine.
Answer
- Skin Rashes: Individuals may experience dermatitis or hives after consuming products containing tartrazine.
- Swelling: Edmunds can develop swelling in various parts of the body, notably around the face and eyes.

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, specifically in the crumbs used for coating. For individuals with gluten intolerance or celiac disease, consuming gluten can trigger immune responses leading to digestive issues and other health problems. Therefore, these fish cakes are not suitable for such individuals.
Step 9
3.5.3 Give reasons why some of the ingredients were irradiated.
Answer
Some ingredients were irradiated to reduce microbial contamination and prolong shelf life. This process helps to eliminate harmful bacteria that may be present, ensuring food safety. Additionally, irradiation can help prevent spoilage by inhibiting the growth of microorganisms, thus retaining the quality and safety of the food.
Step 10
3.5.4 Describe the preservative in the crème fraîche.
Answer
The preservative in the crème fraîche is potassium sorbate. It is used to inhibit the growth of mold, yeast, and other microorganisms, thereby prolonging the shelf life and maintaining the quality of the product. Being effective in small quantities, it allows for the safe consumption of dairy products over extended periods.
Step 11
3.5.5 Discuss how the recommended cooking method for the fish cakes may be beneficial for an obese person.
Answer
Baking the fish cakes, instead of frying, is beneficial for an obese person as it reduces added fat and calories. The method avoids additional sugar and fat that comes from frying, which can contribute to excess energy intake and weight gain. By choosing baking, individuals can enjoy a tasty product while managing their weight more effectively.
Step 12
3.5.6 Evaluate the suitability of the fish cakes in the management of coronary heart disease.
Answer
The fish cakes contain low saturated fat levels, making them suitable for individuals managing coronary heart disease. They provide omega-3 fatty acids which can help lower cholesterol levels and reduce heart disease risk. However, it is crucial to consider the overall diet when incorporating these cakes. Ensuring a balanced intake of fruits, vegetables, and whole grains alongside the fish cakes will contribute positively to heart health.
