Diet—the food people eat—is a central component of health and well-being.
Poor diet and malnutrition are the main drivers of ill health and premature mortality, with negative spillover effects on the environment and economy. What we eat is related to all 17 Sustainable Development Goals (SDGs). Monitoring diet quality globally is thus essential for accountability to nutrition, health, and global development goals. Yet there has been no way of monitoring diet quality in a credible, affordable, and timely way.
The Global Diet Quality Project offers a new approach that enables countries to track diet quality. The project’s Diet Quality Questionnaire (DQQ) allows users to investigate both diet adequacy and diet components that protect against or increase 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
