The US Taskforce On Community Preventive Services reviews the evidence on the effectiveness of population-based health interventions. It publishes the evidence in one-page summaries – ‘The Community Guide’.
In June it published a guide on school-based interventions. This found:
insufficient evidence to determine the effectiveness of multicomponent school-based nutrition interventions in increasing fruit and vegetable intake and decreasing fat and saturated fat intake among school-age children.
