Reducing dietary fat, saturated fat, and sodium and increasing intakes of d ietary fiber and fruits and vegetables are important far cardiopulmonary ri sk reduction. Behaviorally, these dietary changes are very challenging, and in different ways. Fewer than half of U.S. adults have diets meeting recom mended intakes of these constituents, and many do not see a need to align t heir diets with recommendations. Various nutrition education and behavioral counseling approaches have been shown to facilitate changes in fat, fiber, sodium, and fruits and vegetables, but primarily in research settings and among the highly motivated. Practice-based and interdisciplinary studies ar e needed to refine strategies to effect long-term dietary changes, to diffe rentiate behavioral issues for changes involving additions versus deletions from the diet, and to elucidate the roles of sensory, psychosocial, and co ntextual factors in adoption and maintenance.
