The Global Nutrient Database: availability of macronutrients and micronutrients in 195 countries from 1980 to 2013

This study introduces the Global Nutrient Database, a comprehensive resource detailing the availability of 156 nutrients across 195 countries from 1980 to 2013. It addresses a critical data gap in global nutrient supply and consumption. The findings indicate increases in energy availability, fat, and protein contributions globally, while carbohydrate contributions have decreased. The database provides a crucial tool for assessing national food systems' performance in meeting nutritional needs and can inform public health and policy initiatives.
