Trained research assistants or field workers are required to instruct individuals on undertaking a weighed food diary and to provide support during the assessment. The instruction should be done face-to-face and the food diary should be collected and reviewed at the end of the study period. 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).
