Lesson 48 : Assessment of Nutritional Status by Diet Surveys

Methods of diet surveys

Different methods are used for diet survey, such as:

• Oral questionnaire method

• Food inventory or log-book method
  This method of survey can be carried out only when the head of the family or the house wife is literate enough to record all the purchases in the schedule provided for in the diary properly weighing each individual item.

• Weighment of raw foods
  This method has proved to be a more reliable method of survey than others and has been used commonly in studies undertaken in India. In this method the foods are weighed by the worker personally before cooking.
