You can have enough to eat and still suffer malnutrition. That’s because vitamins and minerals are diminished or even extracted during some food processing treatments. So you can have a table of food and still have poor immune system. Healther food = healther people = healthier economies.
One of the things GAIN does is manufacture and supply vitamin and mineral premix which governments and other organizations can purchase. When granaries, mills and even soy sauce packaging companies add the premix to their product, regular consumers get the nutrition at the source (kind of like communities that fluoridate their water).
(Fast Company recently named a for-profit premix manufacturer called DSM as one of the Top 50 Most Innovative companies.)
