The Global Dietary Database
Overview
Comparable and standardized global data on intakes of foods, beverages, and nutrients relevant to chronic diseases have not traditionally been available across nations or key subnational subgroups, and those that do exist have shortcomings. To address these gaps, the Global Dietary Database (GDD) project was created to comprehensively identify, compile, and standardize individual-level data on global dietary factors relevant to health.
GDD is a large, collaborative, ongoing global project to collect, validate, and disseminate data on dietary intakes of major foods and nutrients for children and adults by age, sex, rural vs. urban residence, and level of education. These data capture the scope of the global nutrition transition, ranging from nutritional deficiencies to overnutrition.
This work has generated the most current and reliable estimates of food and nutrient consumption worldwide, particularly in poor and vulnerable populations, and provides reliable and robust data to inform global nutrition policy.
Project Aims
Aim One
To estimate individual food and nutrient intakes worldwide by country, year, age across the lifespan, sex, education level, and urban or rural residence.
Aim Two
To use generated estimates to understand disease burdens, identify high-impact interventions, and evaluate and improve public health and nutrition policies.
Aim Three
To create a public resource and dissemination platform for sharing intake estimates with all stakeholders in the global nutrition community.
Aim Four
To harmonize and publicly disseminate individual-level dietary data at their finest level.
