Resumen
Descripción
The 2010 Dietary Guidelines Advisory Committee and MyPyramid recommend eating a variety
of vegetables and fruit; for vegetables, this recommendation is coupled with specific weekly
serving recommendations. This study used a linear programming model to show the cost of increasing
variety in fruit and vegetable consumption when meeting the Dietary Guidelines for
Americans fruit and vegetable consumption recommendations with no within-group variety. Efficacy
of efforts to promote increased dietary variety may be limited by economic disincentives
associated with purchasing a greater variety of fruit and vegetables.
