Hamburger is a kind of fast food made of cooked patty of ground meat (usually beef, but occasionally pork or a combination of meats) usually placed inside a sliced pieces of bread. The term hamburger originally derives from Hamburg, Germany's second largest city, from where many emigrated to America. Therefore hamburger refers to someone from Hamburg. So hamburger has a relation with Germany.
On the other hand The term "burger" is associated with many different types of sandwiches similar to a hamburger, using different meats, such as a buffalo burger, turkey burger, elk burger, salmon burger, or even a veggie burger.
Most likely hamburger first appeared in the 19th or early 20th centuries. The modern hamburger was a food product that is needed for a society that was rapidly changing due to industrialization, and therefore, people had less time to prepare as well as to consume meals.
The burger is now readily identified with the United States, and a particular style of cuisine, namely fast food. Along with fried chicken and apple pie, the hamburger has become a culinary icon in the United States. The Texas historian Frank X. Tolbert attributes the invention to Fletcher Davis of Athens, Texas. Davis is believed to have sold hamburgers at his café at 115 Tyler Street in Athens, Texas in the late 1880s, then brought them to the 1904 St. Louis World's Fair. An article about Louis' Lunch in The New York Times on January 12, 1974, stated that the McDonald's hamburger chain claims the inventor was an unknown food vendor at the 1904 St. Louis World's Fair. Tolbert's research documented that this vendor was in fact Fletcher Davis. Dairy Queen spokesman Bob Phillips made a similar claim for Dairy Queen in a commercial filmed in Athens in the 1980s calling the town the birthplace of the hamburger.
A hamburger is served with lettuce, bacon, tomato, onion, pickles, cheese and condiments such as mustard, mayonnaise, ketchup and relish. There are various kinds of hamburger such as turkey burger, chicken burger, buffalo burger, ostrich burger, deer burger, hamburger made by mixing seafood or lamb with beef and veggie burger, garden burger, or tofu burger etc. Moreover it can be different in style and ingredients in country to country. Those countries are USA and canada, Mexico, United Kingdom and Ireland, Australia and New Zealand, China, Japan and other countries.
Considered a "high risk" food because of the poor health standards under which they are manufactured. The time consuming process for making processed meats creates high bacteria counts and putrefaction of the meat which need to be treated with chemicals. Putrefaction causes meat to turn green which is then dyed with red chemicals to appear fresh. Unless marked otherwise, hamburger will always contain red dyes. Most hamburger contain the flavour enhancer, MSG (monosodium glutamate) which causes headaches, allergic reactions and more. MSG is a chemical used to fatten up laboratory animals and evidence suggests it will ultimately make you fat when consumed.
