This episode provides the backstory for the development of the Comprehensive Nutrition Gap Analysis (CONGA) developed by the Global Alliance for Improved Nutrition (GAIN) and UNICEF to better measure the number of children who are not meeting their nutritional needs.  The development and use of CONGA are presented in a special supplement issue of Nutrition Reviews.    Dr. Ty Beal from GAIN provides important insight on why this line of research was pursued and its implications as it relates to specific nutrients and also the income gap that is associated with the nutrition gap.
