I can understand the effort and I can support it if the main idea is to prevent people from starving. But I cannot understand people reacting whole foods as it is invented couple of years ago. My 4 years old kid don't consume food other than PediaSure[1] for two years. He really did well until this time and blood, urine test suggest everything is normal. So food replacement is not miracle and works under some circumstances. [1] http://abbottnutrition.com/brands/pediasure http://abbottnutrition.com/brands/pediasure
