Dietary recommendations for the UK population include Dietary reference values (DRVs) and food-based guidelines. The complexities of DRVs and food-based recommendations are translated into the easily understandable visual model the Eatwell Guide.In the UK, government dietary recommendations reflect evidence-based advice from independent expert committees, namely the Committee on Medical Aspects of Food and Nutrition Policy (COMA) and its successor since 2000, the Scientific Advisory Committee on Nutrition (SACN).The revision of the eatwell plate to the Eatwell Guide was led by Public Health England (PHE) in association with the Welsh Government, Food Standards Scotland and the Food Standards Agency in Northern Ireland. In July 2014, PHE established an external reference group (ERG) with an independent chair to provide advice on methodologies for refreshing the eatwell plate. The ERG agreed and recommended that a linear programming approach would be the most robust and objective method for generating food group segment sizes. In order to ensure approaches remained meaningful to the public, consumer research was also conducted.The Eatwell Guide represents UK government advice on a healthy, balanced diet. It was developed with, and is used by, the UK Devolved Administrations (Scotland, Wales and Northern Ireland). The Eatwell Guide is the key nutrition policy tool for health professionals and others working to improve dietary health.The government encourages organizations and individuals to use the national food model to ensure provision of a consistent message.
