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.
Fredrick cel Mare al Prusiei dorea din toata inima sa ii convinga pe germani sa adopte cartoful in alimentatia lor. Deoarece realizaes ca daca ai doua surse de carbohidrati, grane si cartofi, vei avea o volatilitate mai mica a pretului painii.
