Food frequency questionnaire (FFQ) | A food frequency questionnaire (FFQ) consists of a finite list of foods and beverages with response categories to indicate usual frequency of consumption over the time period queried [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)]. | code "C94817" (Food Frequency Questionnaire) from code system "FDA RouteOfAdministration"
Diet history | The diet history method is a detailed retrospective dietary assessment which obtains details of individual foods, and comprehensive information about foods eaten less regularly. It is used to describe usual food and / or nutrient intakes over months or a year [DAPA-Toolkit (https://dapa-toolkit.mrc.ac.uk/diet/subjective-methods/diet-history)]. | code "C17994" (Dietary History) from code system "FDA RouteOfAdministration"
24-h dietary recall | A 24-hour dietary recall (24HR) is a structured interview intended to capture detailed information about all foods and beverages consumed by the respondent in the past 24 hours, most commonly, from midnight to midnight the previous day [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)]. | code "118" (24-h dietary recall) from code system "NFDI4Health_CS_MDS_Remaining_Concepts"
Food record | A food record (also called a food diary) is a self-reported open-ended account of all foods and beverages consumed by a respondent over one or more days [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)]. | code "120" (Food record) from code system "NFDI4Health_CS_MDS_Remaining_Concepts"
Screener | Screeners, also called short dietary assessment instruments: A short food frequency questionnaire, usually without portion size questions or a behavioral questionnaire that asks about general dietary practices (for example, "Do you generally butter your bread?") [NIH Dietary Assessment Primer (https://dietassessmentprimer.cancer.gov/profiles/)]. | code "129" (Screener) from code system "NFDI4Health_CS_MDS_Remaining_Concepts"
Other | Other dietary assessment instrument, which does not fit in the above mentioned categories [NFDI4Health]. | code "C17649" (Other) from code system "FDA RouteOfAdministration"

Rationale | Indication whether the dietary assessment instrument was validated. Validity refers to whether an instrument accurately measures what it is intended to measure. This is typically assessed by comparison to a gold standard using methods like correlations or Bland-Altman plots. It indicates how suitable the instrument is for its purpose and whether it can be applied to other populations beyond the original study.
