Worked Solution & Example Answer:‘Six in ten primary school children are not eating enough fibre.’ (www.bordbia.ie) (a) Give an account of (i) the nutritive value and (ii) the dietetic value of cereals - Leaving Cert Home Economics - Question 2 - 2022
Step 1
(i) the nutritive value of cereals
Answer
Cereals are a vital source of several nutrients, crucial for overall health. They are rich in:
- Carbohydrates: Providing energy for daily activities.
- Dietary Fiber: Essential for digestive health, helping to prevent constipation.
- Vitamins: Such as B vitamins that assist in energy release from food.
- Minerals: Including iron, calcium, and magnesium, important for various bodily functions.
- Protein: Though in lower amounts than animal sources, they contribute to growth and repair.
Overall, cereals serve as an economical source of essential nutrients.
Step 2
(ii) the dietetic value of cereals
Answer
Cereals have significant dietetic benefits, including:
- Dietary Fiber: Helps maintain bowel health and prevents constipation.
- Protein Source: Useful for vegetarians and those looking to reduce meat intake.
- Low Glycemic Index: Many whole grain cereals release energy slowly, keeping blood sugar levels stable.
- Versatility: Can be consumed as breakfast cereals, in baking, or in savory dishes, catering to various dietary preferences.
- Cost-effective: Provides a filling food option that can help save on grocery expenses.
Step 3
Plan a high fibre menu (3 meals, to include a packed lunch) for one day for a school-going child

Packed Lunch
- Brown roll with chicken and cheese
- Apple
- Bottle of water
Dinner
- Vegetable soup with brown bread
- Spaghetti Bolognese with brown pasta
- Glass of milk
Step 4
Outline the effects of heat on cereals
Answer
Heat affects cereals in several ways:
- Gelatinization: Heat causes starch granules to swell, absorbing liquid and becoming thick, which aids in digestion.
- Cooking Methods: Boiling, baking, and toasting can enhance the flavor and texture of cereals, making them more palatable.
- Nutrient Loss: Prolonged heat can lead to the degradation of certain nutrients, particularly vitamins such as B and C.
- Maillard Reaction: This occurs during cooking, resulting in browning and a deeper flavor due to the reaction between sugars and proteins.
- Denaturation of Proteins: Heat changes the structure of proteins in cereals, making them easier to digest.
