Doctors Without Borders is one of the many organizations that is treating malnourished children under the age of 5 with "ready-to-use" therapeutic foods such as "Plumpy Nut," which contain animal protein like milk. Experience has shown time and again that the standard food aid package of blended cereal grain flours does not have the proper nutrients to prevent malnutrition in rapidly growing children under five, or to prevent disease and death in already malnourished children.
Based on this evidence, two things seem apparent:
1) It is unacceptable that we provide foods to babies in poor countries that we wouldn't feed our own babies (i.e. we wouldn't give just cereal to children under 1-year without still supplementing with breast milk or formula).
2) It is pretty clear that cereals have little nutritional value. They may fill bellies and provide caloric energy, but children do not grow or develop because they are eating cereal. This begs the question, "why do we even feed babies cereal at all?"
I am convinced that the human body was designed to survive on animal foods. No sentimentality or ideological beliefs can change this.
