Well, a search for this weblink on Dave's yielded nothing so I'm posting it:

Does Kimchi Cause Cancer - Nutrition Advice From Dr. Katz
Source: www.oprah.com
Dr. David L. Katz, O, The Oprah Magazine's resident nutrition expert reveals the truth about kimchi and stomach cancer.
I know a lot of people have floated around this board the notion that stomach cancer rates are high here. However, this was interesting because it's the first time I've seen any nutritional advice public figure stand up and be willing to be accountable for having said as much.
I wonder if this ever gets on an Oprah episode, if it'll make it past censors to air on the Style channel here in Korea?
I also wonder if Korean nutritionists have already spoken on this subject, or not so much yet? |

It`ll be derided as heresy against the Church of Kimchi and the Land of Kimberly. |

Beaten to the punch.
Seriously, eating/consuming something fermented [and I do like a pint/glass of red wine] or ANYTHING as frequently as Kimberly eats kimchi makes one ponder if kimberly is unintelligent or something.
You know, like Forrest Gump. |

I can see protests over this by the asinine KTU and brainwashed kids who thinks America hates kimchi. |

Q. I grew up in an Asian household and love to eat fermented vegetables like kimchi. But I'm confused about whether these foods are good for me or may pose a risk for stomach cancer because of the fermentation. Are there any studies on this? �Lydia Kang, Omaha
A. Stomach cancer rates are high in parts of Asia, especially Korea, and studies do indeed suggest that at least part of the reason may be all the kimchi, miso, and pickled fish people eat in that part of the world. Those foods contain N-nitroso compounds, which are likely carcinogens.
But that doesn't mean you need to banish them from your table. There are many risk factors for gastric cancer: Genetics, infection with the ulcer-related bacteria Helicobacter pylori, and lifestyle all play a part. If a close relative has had stomach cancer, for example, your risk is apt to be higher than average, which means you should be vigilant about getting checked. And you can be screened and treated for H. pylori infection.
If you eat a diet generally rich in fruits and vegetables of the unpickled variety, you'll lower your risk of stomach cancer. Regular exercise and maintaining a healthy weight will also help.
Otherwise, I recommend recalling the adage from the father of toxicology, Paracelsus: The dose makes the poison. All of us eat carcinogens on a fairly regular basis; our risk is defined by the ratio of beneficial to harmful exposures. Kimchi, miso, and other fermented foods are probably safe as a treat�say, once a week�in the context of a healthy lifestyle. |

Nutrition and health
Kimchi is very spicy and can also be really sweet. Kimchi is made of various vegetables and contains a high concentration of dietary fiber, while being low in calories. One serving also provides up to 80% of the daily recommended amount of vitamin C and carotene.[11] Most types of kimchi contain onions, garlic, and peppers, all of which are salutary. The vegetables being made into kimchi also contribute to the overall nutritional value. Kimchi is rich in vitamin A, thiamine (B1), riboflavin (B2), calcium, and iron,[12][13] and contains a number of lactic acid bacteria, among those the typical species Lactobacillus kimchii.[14] [15] [16][14]
Kimchi has a reputation of being a healthy food. The magazine Health named kimchi in its list of top five "World's Healthiest Foods" for being rich in vitamins, aiding digestion, and even possibly retarding cancer growth.[17] However, some research focused on high-sodium dietary dependence has found overconsumption of kimchi and doenjang (hangul: 된장) to be a risk factor in gastric cancer (most likely due to nitrates and salt) while unfermented alliums and unfermented seafood were found to be protective factors.[18] One oncological study found one type of kimchi to be a protective factor against gastric cancer while two other types of such high-sodium kimchi as dongchimi (hangul: 동치미) were risk factors.[19] |

Washing it back with soju followed by a smoke doesn't help either. |

I have heard that before. The Korean diet is high in sodium and this causes many health problems. For example:

I would say 12oz or 454g (at least) per person. They go through the little banchan dishes like it`s water. Today at my closing ceremony lunch, one table went through 6 dishes of mul kimchi. My principal ate two by himself. |

I'd like to know too. I am a registered dietitian from the US, living in Korea. I banged my head against the wall trying to make contact with the Korean dietetic Association trying to ask similar questions. They finally responded but it was mostly "What will you do with the information", "what is your ID number", "why are you asking questions?". A real treat. They would have gotten a welcome matt in the US. They finally answered some questions I had about medical nutrition therapy in Korea but the process was so unpleasant I gave up trying to get involved, even as a volunteer or guest speaker.
Sorry about the somewhat OT axe grinding.
I do not see much evidence of a real campaign of any kind to address GI cancer by the KDA, KMA or other organizations but I do not speak Korean. It may be a huge campaign but with no graphics so I would have no idea. My memory thinks marketing and health information in the US seems to be more graphic centered than here since we have so many non-English speakers or non-readers. Just a guess. |

When I first came to Korea back in '84, I met an American doctor from Severance Hospital who was doing research on the Korean diet and cancer; however, I don't remember his name. He was looking at all aspects, such as red peppers, salt, etc.
Some years ago, I was warned not to eat homemade 된장 (bean paste), due to the bacteria it has, as it was a potential carcinogen (then again, what isn't?); it was recommended to only eat commercially prepared paste. One of my favorite foods is 청국장 (cheonggukjang), which is a very strong-smelling version; I love it, but I sometimes wonder what they'll say about it. |

A lot of the foods we enjoy here aren`t healthy. Samgyopsal - essentially a piece of lard, jokbal - fat and pig skin, and the list goes on. I remember reading an article on Seoul eats debating the health benefits of Korean food. I`ve come to realize that most of their favs aren`t healthy at all. What do you think Crockpot? |

As the article reads Kimchi can be a contributory cause, much as any other fermented food, beer, wine, pickles, sauerkraut etc.
Do not overlook the main causes, H. Pylori, obesity, and heredity.
He then goes on to say like anything moderation is the key.
For instance many Doctors will tell you the three primary factors for Diabetes type 2, overweight, over 40, and Irish, of course they change the Irish to Mexican or Korean when the patient is Mexican or Korean. |

X,
I can't say my own country has it going on when it comes to balance nutrition (USA). However, I get the impression there is a bit of undue nationalism (?) over the quality of the Korean diet. This may stem from casual observations that bless the diet because ther are a good number of thin people here. My feeling is that thin is not a good indicator of nutritional health as we see better mortality rates with a small amount of additional fat.
If we simply expand out view to look at the crooked ajjumas with spinal osteoporosis, stoke victims dragging themselves down the street, and tubby kids we start to see what's happening. Studying GI cancer, renal fxn, vascular diseases, and even eating disorders would provide a better look. I'd love to get my hands dirty in that stuff on a local level more than merely gawking at WHO stats and making shit up based on guessing.
Specifically regarding foods, I think outside of the sodium, there are good options. As a foreigner I am always guided to goggi of some sort but I have had well ballanced bibimbap (cooked egg) as well as shared some fantastic samgyetang sans skin...ok, I ate it and it was f'n GOOD! I also wonder if the crackpot witch doctors here don't feed into the local food thing. Good for man?
Holy crap I'm rambling. I have felt for a long time that globalization of food if oftne the down fall of a country's diet. people have no idea of the portions they should eat. When i arrived i was wolfing down Samgyopsal not knowing 3-4 other courses where coming. Americans sit down to plates of pasta not knowing that Italians don't do that. We lose touch. |

it's very salty, a bit spicy and widely shared so that the cancer-correlated Helicobacter pylori is spread around
hence the high rates of stomach cancer in this country is no big mystery
except to an ostrich |
