By Dr. Liji Thomas, MDSep 22 2022Reviewed by Benedette Cuffari, M.Sc. Everybody eats; however, the way in which people eat differs on their culture, geography, level of knowledge, and economic status. Moreover, diet is linked to many diseases, with poor diet quality responsible for over 25% of preventable global deaths.
Previous research on dietary quality has been limited, as these studies largely exclude children and adolescents. Furthermore, many of these studies used limited data on food consumption and sociodemographic characteristics such as age, sex, education, and residential area. Assessment of diet quality was performed primarily using the Alternative Healthy Eating Index , with secondary comparative analyses using the Dietary Approaches to Stop Hypertension and Mediterranean Diet Score .
The range extended from 30 in Latin America and Caribbean countries to almost 49 in South Asia. Legumes and nuts had the highest global score, followed by whole grains. Children and adults had similar AHEI scores. However, in Central and Eastern Europe, Central Asia, Northern Africa, and the Middle East, as well as all high-income countries , adults had a much better diet than children. More specifically, U- or J-shaped curves indicated that the best diets were reported in children aged five years or younger and individuals aged 75 years or older.
Urbanites usually had a better diet, except in North Africa and the Middle East. This is likely because of variations in the choice of healthy as compared to unhealthy foods by urban dwellers versus rural communities.
