Potato Diet

[Anomalocaris]

I recall reading about a study conducted by several polish researchers before WWII.  They restricted themselves to a pure potato and milk diet for a period of several month, and found that at the end they suffered neither malnutrition, nor vitamin deficiency, nor  any kind of aversion to the eating potatoes, as people would normally develop after excessively length monotonous diet of single staple.

There is also the fact that before the Irish potato famine, Irish peasants were generally considered to be better nourished, healthier and more strapping than peasants from the rest of UK and other parts of Europe despite being poorer than farmers in the rest of UK and Europe.   This was also attributed to Irish peasantry’s heavier reliance on potatoes for food.
