Information you need to obtain include;-cultural aspects of food consumption, detailed
description of food consumed in terms of frequency of consumption and portion sizes.
b) Food frequency

consumed. Here you have a set of all foods and set of frequency of consumption. Then the
interviewee is expected to indicate how many times a certain food from a particular food
group is consumed or whether is not being consumed at all. Before carrying out the study
you may need a preliminary survey to determine foods commonly consumed in that area.
c) 24 hour recall
In this method you are expected to determine the amount of nutrient consumed by an
individual for the last 24 hours. The purpose of a 24 hour recall is to establish if intake of
nutrient was adequate. You ask the respondent to remembering detail the type and quantity of
foods consumed during the previous 24 hours.
d) Estimated food records
In this method you ask the respondents to record all the foods and beverages consumed at all
the time during meal times. The respondent should give a detailed description of the foods
i.e. amount consumed and ingredients used in the food.
