I think this will work just fine temporarily, and should be looked into for widespread distribution during emergency situations like famines. But doctors first recommended the amazing powdered baby formula in the 50's and 60's and then switched their recommendations back to mothers' milk for most of the population in the 90s. Of course we should continue to experiment and understand nutrition, and powders, potions, and pills can supplement a diet, but I don't think it's anywhere near or ever will be a complete substitute for real food. Real food being healthy, whole foods.
