Potatoes were once banned in France
Potatoes are believed to have been banned in France from 1748 to 1772. The French Parliament reportedly forbade potato cultivation as it was considered to be poisonous, and it was also claimed that potatoes caused leprosy. The ban was revoked by Frenchman Antoine-Augustin Parmentier, who during his imprisonment by the Prussians was fed only potatoes and realised its benefits.
