Worked Solution & Example Answer:'The key to a nutritionally adequate vegetarian diet is balance, ensuring that where foods are specifically omitted, suitable alternatives are included so that dietary quality is not compromised.' (British Nutrition Foundation, Nutrition Bulletin 30) The following table provides information on the nutritive value of minced beef and quorn mince - Leaving Cert Home Economics - Question 1 - 2009
Step 1
Using the information provided in the table, evaluate the contribution of quorn mince to the diet of vegetarians.
Answer
Quorn mince offers several nutritional advantages for vegetarians. It is lower in calories (94 kcal per 100g compared to 225 kcal for minced beef), making it a suitable choice for weight management. The protein content is significant at 14.5g, providing a good source of this macronutrient, which is essential for muscle repair and overall health.
The fat content is also considerably lower at 2.0g, which contributes to heart health and allows for a heart-friendly diet. Moreover, quorn contains dietary fibre (5.5g), which is beneficial for digestive health and can help in maintaining steady energy levels.
Furthermore, while quorn mince does not provide B vitamins like beef, it is a good alternative for those who do not consume meat. Overall, quorn mince forms a valuable component of a balanced vegetarian diet by providing essential nutrients while remaining low in calories and fat.
Step 2
Using quorn mince, plan and set out the menu for a balanced three course meal suitable for a vegan.
Answer
Starter: Quorn Mince Stuffed Peppers
- Ingredients: Quorn mince, bell peppers, onions, garlic, and spices.
- Preparation: Hollow out the bell peppers and fill them with a mixture of sautéed onions, garlic, and Quorn mince, seasoned to taste. Bake until the peppers are tender.
Main Course: Quorn Mince Stir-Fry
- Ingredients: Quorn mince, mixed bell peppers, broccoli, and soy sauce.
- Preparation: Quickly stir-fry the vegetables and Quorn mince in a hot wok with soy sauce, served over brown rice.
Dessert: Vegan Chocolate Mousse
- Ingredients: Avocado, cocoa powder, and maple syrup.
- Preparation: Blend the ingredients until smooth for a rich, healthy dessert.
Step 3
Indicate how the dishes selected meet the requirements of a vegan diet.
Answer
The selected dishes utilize only plant-based ingredients, ensuring they meet the vegan dietary requirements. The stuffed peppers and stir-fry contain no meat, dairy, or eggs, as they use Quorn mince made from fermented mycoprotein, which is suitable for vegans. Additionally, the avocado-based chocolate mousse is entirely plant-derived, containing neither animal products nor by-products, thereby making the entire menu fully compliant with vegan principles.
Step 4
Give an account of vitamin B12 (cobalamin) and refer to: sources in the diet.
Answer
Vitamin B12 (cobalamin) is crucial for red blood cell formation and neurological function. As it is mainly found in animal-derived foods, sources include:
- Dairy products (milk, cheese).
- Eggs.
- Fish and meat.
- Fortified foods (cereals, plant milks).
Step 5
Give an account of vitamin B12 (cobalamin) and refer to: properties.
Answer
Vitamin B12 is a water-soluble vitamin that is generally stable in light and heat. However, it can be destroyed by exposure to ultraviolet rays and certain chemical processes. Additionally, it plays a vital role in metabolism and DNA synthesis.
Step 6
Give an account of vitamin B12 (cobalamin) and refer to: biological functions.
Answer
Vitamin B12 is essential for several biological functions:
- It aids in the formation of red blood cells, preventing anemia.
- It is involved in the metabolism of fatty acids and amino acids, critical for energy production and growth.
- It contributes to the maintenance of myelin sheaths surrounding nerves, crucial for normal nervous system function.
Step 7
Describe some of the measures taken by food manufacturers/ retailers in order to meet the needs of consumers who have specific dietary requirements.
Answer
Food manufacturers and retailers have taken several measures:
- They provide a range of gluten-free and vegan products, understanding the needs of individuals with food intolerances or dietary choices.
- Promote the nutritional benefits of their modified products through labeling and information on packaging.
- Enhance accessibility by providing designated areas in stores for dietary-specific foods, such as organic sections or gluten-free aisles.
- Conduct in-store demonstrations to educate consumers about specific dietary products and their uses, thereby promoting informed consumer choices.
