Ammerman AS, et al. The efficacy of behavioral interventions to modify dietary fat and fruit and vegetable intake: a review of the evidence. Prev Med. Jul 2002;35(1):25-41.
The authors evaluated the overall effectiveness of behavioral dietary interventions and explored the effectiveness of specific intervention features. Most studies found that interventions led to improvements in dietary behaviors to prevent chronic disease. Because studies varied in design, analysis techniques, and outcome measures, researchers could not draw broad conclusions about the most effective components of the interventions.
