Resources required
Trained research assistants or field workers are required to instruct individuals on completing an estimated food diary and to provide support during the assessment. The instruction can be done face-to-face or via the telephone. The estimated food diary should be reviewed at the end of the study period, again either face-to-face or via the telephone. Out of hours home visits and phone calls may be required.
The process of coding and conversion of data to nutrients is time consuming and labour intensive and requires trained diet coders and a nutrient database and analysis program (see data processing section).
