Doenjang is considered one of the essential sauces of authentic Korean cuisine. However, the condiment has historically been unknown outside of Korea, although recent international articles have resulted in an increase in its popularity. A 2007 Chinese article on the "Sauces of Korea" listed doenjang and gochujang as essential flavorings, and explored the origins of the condiments, particularly focusing on Sunchang County, where most Korean soy sauce is produced. The article pointed out that doenjang does not contain any artificial additives and in fact has healthy amounts of essential vitamins, such as vitamin C and vitamin B12. The health benefits of doenjang are rumored to extend longevity, and this is illustrated by the fact that out of the 32,000 people in Sunchung County, eight are over 100 years old, and many are over 90. The article was influential throughout China, resulting in many Chinese restaurants adding doenjang jjigae modified slightly to Chinese tastes, to their menus shortly after publication. South Korea's JoongAng Ilbo covered this story in China on December 13, 2007.
