OHID London are hosting an expert-led presentation and discussion on Planning and Health.The planning system is a legal determinant of health. Planning policies (national and local) and the planning decision-making process play a key role in shaping the kind of environment people access on a daily basis. This session focuses on the food environment and how the planning system (policy and decision-making) can help promote a healthy weight environment. It will illustrate the planning system in action with a particular highlight of how successful and unsuccessful local authorities have been in introducing planning policies, and in defending against planning appeals for less healthy food and wider retail outlets.
