Monotonous but sustainable

Potatoes contain nearly all important vitamins and minerals, they support life better than any other crop when eaten as the sole article of diet. Humans can subsist healthily on a diet of potatoes, supplemented with only milk or butter, which contain the two vitamins not provided for by potatoes, vitamins A and D. This, in fact, was the typical Irish diet, which although monotonous, was able to provide sufficient amounts of all vitamins and nutrients.
