Harmonizing and mainstreaming the measurement of healthy diets

Book excerpt: With rapidly changing diets, the burden of disease due to the consumption of unhealthy diets is a worldwide concern. Assessment and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the world is evolving. Recognizing the need for consensus and action, and to chart a way forward, FAO, UNICEF, and WHO established the Healthy Diets Monitoring Initiative (HDMI) in 2022. The joint mission of this Initiative was articulated through discussions at a technical expert meeting in Bellagio, Italy, in late 2022. This meeting report includes the discussions and conclusions made on the suitability of existing metrics for assessment and monitoring of healthy diets nationally and globally. It also includes a workplan roadmap for the HDMI for the next two years towards the development of a global guidance on healthy diets metrics.
