The Global Diet Quality Project aims to enable diet quality monitoring globally with tools and data. It is a collaboration between Gallup, Harvard University, and the Global Alliance for Improved Nutrition (GAIN), in collaboration with many global stakeholders. The project’s Diet Quality Questionnaire (DQQ) allows users to investigate both diet adequacy and diet components that protect against or increase the risk of noncommunicable diseases (NCDs). Working with the Gallup World Poll data collection platform, the project has assembled the first round of diet quality data for over 40 countries in 2021 and aims to collect data for 140 countries.
