Worked Solution & Example Answer:1. The table shows the iron content in various foods - Leaving Cert Home Economics - Question 1 - 2008
Step 1
Step 2
Step 3
The recommended daily allowance (RDA) of iron for a teenage girl is 15 mg. List three food items from the table that can be included in her diet to help her meet this recommended daily allowance.
Answer
- Calves' Liver (12.2 mg)
- Black Pudding (9.2 mg)
- Minced Beef (3.1 mg)
These items can be combined to exceed the RDA.
Step 4
Calculate how much more iron is needed for her to meet the recommended daily allowance of 15 mg.
Answer
To calculate how much more iron is needed, we first consider the amounts provided by the chosen foods.
For example, if a teenage girl consumes Calves' Liver and Black Pudding, the total would be:
- Calves' Liver: 12.2 mg
- Black Pudding: 9.2 mg
However, combining these would yield 12.2 + 9.2 = 21.4 mg, which exceeds the RDA. In a case where only Calves' Liver is consumed, she would still require an additional: to meet the RDA.
Step 5
Identify food items from the table that are better sources of iron than others. Give reasons for your choice.
Answer
Better sources of iron include:
- Calves' Liver - highest iron content at 12.2 mg.
- Black Pudding - significant iron content at 9.2 mg.
- Minced Beef - moderate iron level at 3.1 mg.
These choices are based on their higher milligram content of iron, making them more effective for meeting dietary iron needs.
