That's a very good question.
The situation we face is complex, because some people do consume food, but it just doesn't contain much nutrition, although maybe it contains some of the other macronutrients they need. For those, we do need to fortify the foods if we can. We can fortify condiments like salt and we can fortify wheat flour, maize flour, vegetable oils, and all kinds of things for really just a few cents. For example, the cost of fortifying wheat flour per person per year is about seven cents, so if they're getting a great enough quantity of food, you can add nutritional value to it there. That's one segment of the population.
However, those in another segment of the population are simply hungry. They just don't have enough food at all. Plumpy'Nut—and, if I recall, in the Plumpy family there are several products—also replaces some of the other nutrients in addition to the micronutrients, but there the cost is very different. The cost per child per year for Plumpy'Nut is around $50 U.S.
You can see the cost differential. If you are trying to serve the needs, there are 180 million children in need in Africa alone. That's an awful lot of emergency and therapeutic feeding you would do for that population.
Now, if you could mobilize the resources, that would be great, but, if we treat this as a market, we're actually looking for the right solutions for the different segments of the market that have slightly different needs.
