Question
Chapter 19, Problem 3CHQ
Interpretation Introduction
Interpretation:
Some examples of foods rich in iron should be provided.
Concept introduction:
- Iron (Fe) belongs to the
transition metal series in the periodic table and plays a vital role in the human body - It present in blood hemoglobin and is involved in the transportation of oxygen to different parts of the body
- Lack of iron in the blood results in anemia and therefore it needs to be supplemented through food. For example, through cereals fortified with food grade iron filings
- A strong magnet can be used to test the presence of iron in a mixture of iron fortified cereals
