Large scale food retail interventions and diet

First paragraph: Ensuring communities have good access to healthy affordable food is one of the government's joined up strategies to improve public health and reduce health inequalities. Policy solutions for deprived communities without good access - food deserts - have focused on improving provision of food retail as part of a wider suite of recommendations for population dietary change focused around awareness, affordability, and acceptability. However, the evidence for the widespread existence of food deserts and their impact on population health has been contested. This has meant that although retail based policy recommendations to reduce diet related health inequalities now exist, the evidence to inform how, when, and where to reduce these inequalities is only now emerging.
