Fredrick the Great of Prussia was very, very keen for the Germans to adopt the potato and to eat it, because he realized that if you had two sources of carbohydrate, wheat and potatoes, you get less price volatility in bread.
Frederico o Grande da Prússia queria muito que os alemães adotassem a batata, que a comessem, porque se apercebeu que, se tivessem duas fontes de hidratos de carbono, trigo e batata, teriam um preço do pão menos volátil.
