Worked Solution & Example Answer:Cereals are the staple food of many countries - Leaving Cert Home Economics - Question 3 - 2018
Step 1
Give an account of (i) the nutritive value and (ii) the dietetic value of cereals.
Answer
Nutritive Value
Cereals are a rich source of low biological value (LBV) protein, carbohydrates, and dietary fiber. They provide essential nutrients such as vitamins and minerals.
- Protein: Important for growth and repair of body tissues.
- Carbohydrates: Main source of energy, crucial for bodily functions.
- Vitamins & Minerals: Includes B vitamins, iron, calcium, and phosphorus which play vital roles in various body functions.
- Fiber: Aids in digestion and helps in preventing constipation.
Dietetic Value
Cereals are versatile and can be integrated into various meals. They are low in fat and contribute to heart health. Their high fiber content aids digestion while promoting a feeling of fullness, which may help in weight management. Additionally, some cereals can support specific dietary needs, such as gluten-free options for coeliacs.
Step 2
Step 3
In relation to cereals: (i) explain the difference between white (plain / cream) flour and wholemeal flour
Answer
White flour is made from the endosperm of wheat, where the bran and germ are removed, resulting in a finer texture. This flour is fortified with vitamins but generally has lower fiber content compared to wholemeal flour. Wholemeal flour, on the other hand, is made from the entire grain, retaining the bran and germ, which results in a higher fiber content and nutritional value.
Step 4
(ii) outline three guidelines to consider when storing cereal products.
Answer
- Store in a Cool, Dry Place: Keep cereal away from moisture and heat to prevent spoilage.
- Use Airtight Containers: This helps in preserving freshness and prevents contamination from pests.
- Best Before Dates: Always check and adhere to the best before dates to ensure the quality and safety of the cereal.
