Summary

Defining fruits and vegetables (F+V) is crucial for tracking dietary goals. Different F+V definitions impact intake measurements, highlighting the need for a standardized approach to assess fruit and vegetable consumption accurately.

Area of Science:

  • Nutrition Science
  • Dietary Assessment
  • Public Health Goals

Background:

  • Current nutrition guidelines advocate for increased fruit and vegetable (F+V) consumption.
  • A Year 2000 public health objective aimed for at least five daily servings of F+V.
  • Standardized definitions of F+V are necessary for accurate measurement of goal achievement.

Purpose of the Study:

  • To evaluate how different definitions of fruits and vegetables (F+V) affect the assessment of dietary intake.
  • To determine the impact of including or excluding legumes and using narrow versus broad definitions of F+V.
  • To highlight the need for a clear, consistent definition of F+V for public health monitoring.

Main Methods:

  • Developed four distinct definitions of F+V: narrow and broad, with and without legumes.

  • Applied these definitions to food frequency data collected from 133 children and 211 parents.
  • Analyzed mean and median intake levels based on each F+V definition.

    • Main Results:

    • Mean F+V intake met or exceeded the five-serving goal across all definitions for both children and adults.
    • Median intake met the goal for most definitions, with exceptions noted for children under a narrow definition without legumes.
    • Significant variations in goal achievement were observed depending on the F+V definition used.

    Conclusions:

    • The definition of fruits and vegetables significantly influences the interpretation of dietary intake data.
    • A lack of a standardized F+V definition complicates the accurate measurement of public health goals.
    • Establishing a clear and consistent definition of F+V is essential for effective nutrition monitoring and policy development.
