Following on from Cecil’s answer to “can man live by bread alone” (see here. Basically, no, and it would be a horrible, painful demise.)
I wonder, is there any one simple thing that man can live on alone? And if not, what would be the simplest healthy diet (only 2 or 3 things?)
Looking around I’ve found a few suggestions that pop up again and again: oatmeal, potatoes, bread, bananas, apricots, peanut butter, cereal, milk…
But there doesn’t seem to be a conclusive answer anywhere. I’m sure there’s some way you could cheat nature by wolfing two foods and a multivitamin, but would anyone out there be able to clarify?
