Pros and cons

Pros

• Respondent burden is relatively low
• Procedure does not alter food intake patterns
• Literacy not required
• Interview relatively quick (e.g. 20-30 minutes)
• Web based applications vastly reduce administration cost but more research is required to ascertain accuracy and reliability

Cons

• Single 24 hour recall not representative of habitual intake but may be useful for group means
• Method dependent on respondent’s ability to recall intake accurately
• Possibility of recall bias where the individual may selectively recall food items, as with all self-report methods
• Expensive to administer due to high interviewer burden but telephone 24-hour recalls can reduce cost
• Repeat 24-hour recalls increase time and cost of analysis
