[Epub ahead of print] A randomized feasibility trial of brief telephone counseling to increase fruit and vegetable intakes.
OBJECTIVE: This study examined the feasibility of eliciting dietary changes in subjects recruited from a diverse primary care setting in Michigan using a written, one-page plan, either alone or with telephone counseling.
Group 2 received written materials plus a one-page form that asked them to make a specific daily plan for substituting one less nutritious food with two servings of fruits and vegetables.
Subjects in Groups 1, 2 and 3 changed their mean intakes of fruit and vegetables by 0.4, -0.7 and 1.4 servings/day, respectively.
Participants in Group 3 lost an average of 0.73 kg, increased their perception of the importance of eating fruits and vegetables, and 63% increased their serum levels of carotenoids by 20% or more.
Formulation of a written plan combined with telephone counseling appears to be promising for improving fruit and vegetable intakes and warrants more definitive study.
