Ok let's really look at the requirements for human chow. #1 off nutrition it will have to be nutritionally sound I had a friend that decided Mac and cheese was all the food he really needed and it took longer that you might think for his dermatologist to diagnose scurvy ...you just don't see I that much anymore. B most"health" products are designed to put on muscle without regular exercise these will make you obese and you will die of heart attack. Tertiary a lot of seaweeds like spirolena while claiming to be the best food for you taste like crap and if you look close they are best at making other foods give you the benefits better and don't work we'll without other foods being eaten. Next moth feel Penn says its important but I think we can fix this on whatever fits the other criteria. Which brings me to my best guess, I you go to a hospital, retirement village, burn center, ect. And look at what doctors think you always fing if you can get some Ensure don't them every day they won't have to go on a feeding tube. It has everything to sustain life without anything else being eaten. The only thing it doesn't have is mouth feel so we need to find a way to make it into nuggets I would suggest mixing powdered ensure with maybe oval time and a little sugar melt it down and post into a flat pan when hardheaded break it up and poof human chow. I would relish comments and suggestions before I trash my kitchen trying this.
