Not sure I agree.
People who survived prison and concentration camps survived unscathed.
Not only that, but they say Europe was at its healthiest when food rationing was around.
Apparently WE are the first generation without civilian war that will be outlived by its parents, due to protein and calorie overload.
Can humans survive on any single food? A whale or other marine mammal might do the trick. Some Inuit have survived long periods entirely on meat, attaining vitamin C in muktuk, the skin and blubber of whales.
Surprisingly, potatoes offer a complete protein if you eat enough, over 10 per day. But you would ultimately encounter deficiencies in vitamins A, B12 and E, and calcium and selenium if you keep to just potatoes.
Potatoes are slightly toxic, too. The poison is in the stem and leaves, but trace amounts can be in greenish spots on the potato itself and can cause serious illness if you eat enough.
In eating any single vegetable, you are sacrificing nutrients. Soybeans, chickpeas, lentils, or carrots also provide a good range of nutrients.
