Publication: Dietary intake assessment: 24-hour recall
Purpose of manual
The use of a 24-hour dietary recall within the context of food security
Dietary intake data collected by 24-hour recall can be used to:
– determine the types of food and liquids consumed
– assess average nutrient intakes for groups of >50 individuals per group
– calculate dietary diversity scores 1,2
– calculate dietary quality scores
– evaluate food intake in terms of food-based dietary guidelines 3
– determine food patterns
– determine the contribution of specific foods to nutrient intake
A single 24-hour recall cannot be used for the habitual dietary intake of an individual.
The content of the manual (e.g. the language use, foods) is relevant to the South African context at the time of the development of the manual.
IMPORTANT: The intention of this manual is not to cover ALL different types of food on the market, but rather to sensitise the researcher to the pitfalls to look out for. New types of food and beverages enter the market daily. It is the responsibility of the researcher to familiarise her/himself with the latest foods and beverages available on the market and include it as examples in the dietary kit.
