which countries has the most diverse food?

Countries with vast areas with various geological structures, profound histories, or chill life styles usually have a wide diversity of food choices. For example, China has 3.7 million square miles area and over 50 different ethnitical groups. Each ethnicity has its own culture and living styles, thus different cuisine styles and tastes. The United States is another example with almost 3.8 million square miles of area and immigrants from all over the world. As a results, the immigrants and their descendants bring in food culture from their original heritage that creates a huge variety of choices in the US. South European areas like Rome have stellar reputation for their food too. When it comes to pizza, pasta, seafood, coffee and gelato, no one could say no when visiting Italy.
