Kostholdsdatabank

Kostholdsdatabank is a centralized repository designed to store and integrate data related to diet, foods, nutrients, and dietary intake. It supports data collection, harmonization, and analysis for research, public health, and policy making. A kostholdsdatabank typically includes food composition data (nutrient values per unit, such as per 100 grams or per serving), records of individual or population-level dietary intake (from recalls, records, or questionnaires), as well as related information about portion sizes, recipes, and food items.

Data quality and metadata: Each entry includes metadata on data source, date, measurement units, population group, and methods used. The database may also store study identifiers, participant demographics, and calibration factors to adjust for measurement error.

Data sources and interoperability: Kostholdsdatabank aggregates data from national dietary surveys, laboratory analyses, industry databases, and international food composition tables. Interoperability is supported by the use of standard coding schemes to map foods and nutrients across datasets, enabling cross-study comparisons and data sharing.

Access, governance, and privacy: Kostholdsdatabank is typically maintained by government agencies, public health organizations, or research consortia. Access ranges from restricted use for privacy and licensing to publicly available data. Privacy and ethical considerations apply to any individual-level data, with de-identification and governance procedures in place.

Uses and limitations: The database is used to estimate nutrient intakes, monitor dietary trends, support nutrition guidelines, inform clinical recommendations, and evaluate policy impacts. Limitations include potential data that are outdated or incomplete, variation in measurement methods, and underreporting or misreporting among respondents.
