Abstract
Various nutrition guidelines recommend increased consumption of fruits and vegetables (F+V); a Year 2000 goal targets five or more daily servings of F+V. Decisions are needed regarding how to define F+V to facilitate measurement of goal achievement. Four alternative definitions (narrow and broad, each with and without legumes) were developed and applied to food frequencies from 133 children and 211 parents. Results varied by definition. Mean intake met the goal of five or more daily servings regardless of definition and exceeded it for both broad definitions by children and both broad definitions and the narrow definition with legumes for adults. Median intakes met the goal for all definitions except for children with the narrow definition without legumes, and exceeded it for children with both broad definitions and for adults with the broad definition with legumes. These differences by definition indicate that a clear definition of F+V is needed.
