Okinawan traditional cuisine is believed to play a big part in the famed Okinawan longevity. The cuisine consists of a reasonable amount of protein, mostly in the form of pork, and plenty of fresh vegetables and seaweeds. Fish, mostly from coastal waters, is also essential. Even the common folk in Okinawa have always understood the importance of a healthy cuisine as expressed in the saying "Nuchi Kusui" meaning roughly "food is medicine." To this day, foods such as "Tofu Champuru," stir-fried mix of vegetables and everything else, and "Okinawa Soba" are the staples of Okinawans' everyday diet.
