Worked Solution & Example Answer:The following is the nutritional value of Textured Vegetable Protein (TVP) and lean minced beef - Junior Cycle Home Economics - Question 1 - 2013
Step 1
Using the nutritional information given on the table: (i) Compare the food value of TVP with lean minced beef.
Answer
When comparing the nutritional values of Textured Vegetable Protein (TVP) and lean minced beef, the following points can be noted:
- Protein Content: TVP has significantly higher protein at 74 g compared to 23.1 g in lean minced beef.
- Fat Content: TVP contains only 2 g of fat, whereas lean minced beef has 14.5 g, making TVP a lower-fat option.
- Carbohydrate Content: TVP offers 10 g of carbohydrates, including 5.5 g of fiber, while minced beef has 0 g of carbohydrates.
- Minerals: Both foods provide calcium, but TVP does not contain iron, implying that people who rely solely on TVP might need to consider sources of iron in their diet.
- Vitamins: Both options contain Vitamin B, but details on the specific types may vary.
- Water Content: Beef has a high water content at 59 g, making it more hydrating, while TVP has none, necessitating additional hydration when consumed.
Step 2
Using the nutritional information given on the table: (ii) Give one function of each of the minerals listed and explain how a deficiency of these minerals can effect the body.
Answer
-
Calcium:
- Function: Essential for healthy bones and teeth; it plays a crucial role in muscle contraction and nerve function.
- Deficiency Effects: A lack of calcium can lead to conditions such as rickets in children (softening of bones) and osteoporosis in adults, making bones brittle and susceptible to fractures.
-
Iron:
- Function: Vital for the formation of hemoglobin in red blood cells, which carries oxygen around the body.
- Deficiency Effects: Iron deficiency can result in anemia, characterized by fatigue, weakness, and diminished immune function due to inadequate oxygen supply to various body tissues.
