Despite recognizing the potential of retail settings for interventions aimed at bringing the rate of obesity down, there have been few attempts to implement experimental studies aiming to increase consumption of healthy foods and decrease consumption of unhealthy foods in the retail setting. An experimental controlled trial has been conducted using 10 supermarkets in Denmark. The study looked specifically into the possible effect of shelf space management intervention at supermarkets. The study found a significant intervention effect for individual products targeted by the project. But overall, care is needed to interpret results on aggregate level since statistical findings do not support category wide effect of shelf space intervention.
