Although popularly considered as a single cuisine, Thai food would be more accurately described as four regional cuisines corresponding to the four main regions of the country: Northern, Northeastern (or Isan), Central, and Southern, each cuisine sharing similar foods or derived from those of neighboring countries. Southern curries, for example, tend to contain coconut milk and fresh turmeric, while northeastern dishes often include lime juice. The cuisine of Northeastern (or Isan) Thailand is heavily influenced by Laos. Many popular dishes eaten in Thailand were originally Chinese dishes which were introduced to Thailand mainly by Teochew people who make up the majority of the Thai Chinese. Such dishes include jok, kway teow rad na, khao kha moo (also known as moo pa-loh) and khao mun gai.
Thai food is known for its enthusiastic use of fresh (rather than dried) herbs and spices as well as fish sauce. Thai food is popular in many Western countries.
