Accurate dietary intake calculations require reliable nutrient databases. This study details methods for selecting and documenting data sources to ensure nutrient value accuracy.

Area of Science:

  • Nutrition science
  • Food science
  • Data management

Background:

  • Accurate dietary intake assessment relies on comprehensive nutrient databases.
  • Existing databases often use U.S. Department of Agriculture data, supplemented by other sources.
  • Establishing clear guidelines for data selection and documentation is crucial.

Purpose of the Study:

  • To identify data sources utilized by the Nutrition Coordinating Center (NCC) at the University of Minnesota.
  • To describe the procedures for selecting and documenting nutrient values within the NCC nutrient database.
  • To ensure the reliability and accuracy of dietary intake calculations.

Main Methods:

  • Review and identification of primary data sources for the NCC nutrient database.

  • Development of guidelines for evaluating the reliability of nutrient data.
  • Implementation of a system for precise documentation of data origins (e.g., chemical analysis, recipe calculation, imputation).

    • Main Results:

    • The NCC nutrient database incorporates data from multiple sources, including the U.S. Department of Agriculture.
    • Specific criteria were established for selecting the most appropriate nutrient values.
    • A robust documentation system tracks the origin of each nutrient data point.

    Conclusions:

    • The methods described enhance the reliability of nutrient databases.
    • Accurate data selection and documentation are essential for precise dietary intake calculations.
    • The NCC's approach provides a model for maintaining high-quality nutrient information.
