Kimchi consists of mainly fermented cabbage and spices and is prized as one of Korea's national dishes. It is characterized as being acidic and spicy in flavor and produces a slightly sour odor due to the fermentation process. Kimchi is packed with essential vitamins and minerals that provide many healthful benefits.Although kimchi is a popular dish in modern times, the fermentation process originated as a way to preserve foods during the winter. In June 2011, the Korean Spiritual and Culture Promotion Project published an article in which "Health" magazine declared kimchi to be one of the world's top five healthiest foods. This is due in part to the fermentation process, which encourages healthy bacterial growth along the intestinal tract. At least 200 Korean dishes contain a side of kimchi, which is often fermented with spices such as garlic and chili.
