Anyone for kimchi(韩国泡菜)？ Around 2,000 women made the traditional dish last week in Seoul, the capital of the Republic of Korea(ROK).

More than 270 tons of kimchi were produced and handed out to needy neighbours.

In the ROK, kimchi is more than a dish to be eaten with every meal, even though Koreans are said to eat about 40 pounds(around 18kg) of kimchi per person each year.

According to Korean.net, the country’s official multilingual website, kimchi represents

“the spirit” of the Koreans.

Kimchi traditionally has a rosy color. Korea.net says: “The color red wards off (避开) evil spirits. The color represents the spirit of the Korean people and kimchi is more than just a food. It’s a culture.”

A meal without kimchi is unthinkable. So what is kimchi?

Joan Raymond, food writer for US website health.com, writes: “It’s a reddish, fermented (发酵的) cabbage dish , made with a mix of garlic salt, vinegar, chili peppers and other spices.

It is served at every meal, either along with or mixed with rice and noodles. It is part of a high-fiber, low fat diet, which has kept obesity(肥胖) at bay.”

Kimchi is used in everything from soups to pancakes and as a topping (配料) on pizza and burgers.

Health.com named kimchi in its list of the world’s top five healthiest foods as it is rich in vitamins, aids digestion and may even reduce the risk of cancer.

A study conducted by Seoul National University claimed that chickens infected with the H5N1 virus (bird flu) recovered after eating food containing the same bacteria found in kimchi.
