The terms Freedom Fries and Freedom Toast were created in 2003 to replace French fries and French toast, to express dismay with France by Republicans Bob Ney and Walter B. Jones. The Congressional Cafeterias changed the name back to French fries in 2006. It is a good example of a political fad that had a short life.
During the First World War, some Americans called sauerkraut 'liberty cabbage' in an attempt to disassociate themselves with all things German.
Interestingly enough, "French Fries" and "French Toast" are not actually food derived from France. French fries are a culinary concept that originated in the French quarter of Switzerland, and "French Toast" originally is derived from the French Community of Belgium (Wallonia). Both terms and concepts arrived in the United States of America from soldiers returning from World War I.
