Sustainable Diets condense into a single idea the multiple challenges facing the food system, taking in all elements of the complicated chains and webs that connect food producers through intermediaries to eaters, and the twin needs to support public health and also restore the environment. Inevitably, they will be an overarching goal of the food policy to be developed in the UK in the near future. But while Sustainable Diets have hitherto attracted little attention from policy-makers, they have long been discussed and put to the test by academics and civil society organisations. To help make this knowledge and experience available to policy-makers, the FRC conducted a survey. What do experts from academia and civil society consider to be the most important policy priorities for achieving Sustainable Diets? This report presents the results, and shows a high level of consensus around key topics.
