Tesfaye Hailu Bekele (PhD) is a nutrition researcher in healthy diet development, evaluation, and adherence monitoring. Tesfaye led the Ethiopian Food-Based Dietary Guidelines and a Healthy Eating index development and evaluation from 2018-2022 through the food system for a healthier diet flagship and financial support from the food and agriculture organization of the United Nations. In the future, he would like to work on characterizing diet as an Individual, if possible at the meal level, understanding the main cause of an unhealthy diet, and understanding the challenge of the food system. Tesfaye would like to work on dietary intervention implementation research or impact evaluations more on a broad aspect of the food system. He is interested in developing tools using advanced technologies to make dietary assessment easy in low and middle-income settings. In general, he is interested in working on how to make a healthy diet more easy, accessible, and affordable. Currently, Tesfaye is working on Global Diet Quality Project to validate the diet quality questionnaire in his postdoctoral research. A diet quality questionnaire is a tool developed for more than 130 countries to assess nutrient adequacy and dietary risk for non-communicable diseases. Tesfaye is involved in evaluating the indicators for the diet quality questionnaire as a post-doctoral researcher.

My postdoctoral research is on Global Diet Quality Project 

Motivation and Aims

This project aims to collect dietary quality data in the general adult population across countries worldwide, and to provide the tools for valid and feasible diet quality monitoring within countries. The project enables the collection of consistent, comparable dietary data across countries for the first time.


The Global Diet Quality project provides two main global public goods:

Diet Quality Questionnaire (DQQ) module takes 5 minutes to implement and adapt for each country. The DQQ is an internationally standardized survey instrument that works universally while also capturing local realities and can be used to interpret diet quality within and across countries. Country-adapted DQQ modules can be easily implemented and analyzed by any survey team interested in gathering information on diet quality. The availability of these low-burden tools is intended to facilitate and catalyze diet quality monitoring in countries and across sectors.

Data on diet quality across countries. The Gallup World Poll is implementing the DQQ, starting with the first phase in 56 countries in 2021-2022. A suite of diet quality indicators will be reported, capturing dietary adequacy and dietary risk factors for noncommunicable diseases (NCDs). The data will enable monitoring of trends, and comparisons across different ages, gender, income, and urban/rural populations. Furthermore, DHS (the Demographic and Health Surveys) is implementing selected questions of the DQQ for women and aligned questions for infants and young children.

As part of this research project, I am involved in data cleaning, analysis, interpretation (writeup of report and research findings), and assisting the overall coordination. 


I had a bachelor's degree in Applied Chemistry from Jimma University in 2007 and a master's of science in applied human nutrition from Hawassa University in 2013, and  PhD in public health nutrition in 2022 from Wageningen University and Research.
