Tom is suffering from two conditions. First, he is suffering from insufficient iron which leads to poor formation of hemoglobin hence leading to anemia. Second he is also suffering from poor appetite, a condition which may aggravate the anemic condition. Due to poor appetite, his food intake is irregular. Sometimes he has high appetite while other times his appetite is low. Consequently, it would be difficult to assess his diet over a short period time which rules out assessment methods like 24-hour recall. Tom is a young boy which means he would not be in a position to administer food frequency questionnaire. On the other hand, director observation would be an appropriate method but it would not work in this case because of infrequent food intake pattern. It would therefore be difficult to keep a consistent and accurate record of food intake. Considering the inconsistency in food intake, the best tool that can be used to correct dietary information from is a food record because his food intake is inconsistent. This would allow recording his diet over a period of time. This would ensure that the component and portion size of food he takes would be recorded over a defined period of time (Gibson 1993: 71).
