I am not sure there is anything 100% nutritious available at a grocery store. Maybe we could find some kind of completely nontoxic food substitute and charge it with all the necessary nutrients. Then, with water distillers in all our houses, we could eat VitaPure food substitutes and drink clean water. I'm stuck now on how to simulate half and half to put in my coffee and then I think I will have all my alimentary needs covered....
