Guest guest Posted February 1, 2004 Report Share Posted February 1, 2004 OK, well HERE is an interesting take on kimchi and cancer: http://reviews.bmn.com/medline/search/record?uid=MDLN.21659644 & refer=scirus Abstract To assess gastric cancer (GC) risk in relation to dietary intake in Korea, a case-control study was performed. Trained dietitians interviewed 136 patients diagnosed with GC, and the same number of controls were selected by matching sex, age and hospital. A significant decrease in GC risk was observed with increased intake of Baiechu kimchi (prepared with salted Chinese cabbage and red pepper, etc.), Baiechu kimchi-stew, garlic, mushroom and soybean milk. On the contrary, a significant increase in the risk of GC was observed with increased intake of cooked rice with bean, charcoal grilled beef, pollack soup, Kkakduki (a kind of kimchi prepared with salted radish and red pepper, etc.), Dongchimi (a kind of kimchi prepared with radish and a large quantity of salt water) and cooked spinach. In food groups, increased intake of soybean products was associated with decreased risk of GC. Intake of citrus fruits rather than total fruits was shown to have a protective effect on the risk of GC, but was not significant. In this study, intake of total vegetables was shown to have a protective effect, whereas high nitrate-containing vegetables increased the risk of GC. In conclusion, our study suggests that the risk of GC decreased with high consumption of fresh vegetables and fruits, whereas high consumption of foods rich in nitrate and carcinogenic substances produced during the cooking process increased the risk of GC. So cabbage kimchi decreases risk, radish kimchi may increase it? And spinach increases it? And soybeans decrease it? Hmmm ... -- Heidi And for the technically inclined, here is now bacteria CAN eat nitrates (whether and how they do in kimchi I leave for better minds). http://www.bact.wisc.edu/MicrotextBook/Metabolism/totalText.html Nitrate reduction Some microbes are capable of using nitrate as their terminal electron accepter. The ETS used is somewhat similar to aerobic respiration, but the terminal electron transport protein donates its electrons to nitrate instead of oxygen. Nitrate reduction in some species (the best studied being E. coli) is a two electron transfer where nitrate is reduced to nitrite. Electrons flow through the quinone pool and the cytochrome b/c1 complex and then nitrate reductase resulting in the transport of protons across the membrane as discussed earlier for aerobic respiration. N03- + 2e- + 2H+{imageref( " arrow " )}N02-+ H20 Figure 34 - The reaction for nitrate reduction. N03-, nitrate; N02-, nitrite This reaction is not particularly efficient. Nitrate does not as willingly accept electrons when compared to oxygen and the potential energy gain from reducing nitrate is less. If microbes have a choice, they will use oxygen instead of nitrate, but in environments where oxygen is limiting and nitrate is plentiful, nitrate reduction takes place. Denitrification Nitrite, the product of nitrate reduction, is still a highly oxidized molecule and can accept up to six more electrons before being fully reduced to nitrogen gas. Microbes exist (Paracoccus species, Pseudomonas stutzeri, Pseudomonas aeruginosa, and Rhodobacter sphaeroides are a few examples) that are able to reduce nitrate all the way to nitrogen gas. The process is carefully regulated by the microbe since some of the products of the reduction of nitrate to nitrogen gas are toxic to metabolism. This may explain the large number of genes involved in the process and the limited number of bacteria that are capable of denitrification. Below is the chemical equation for the reduction of nitrate to N2.

Guest guest Posted February 1, 2004 Report Share Posted February 1, 2004 Ah really. Even if they don't list MSG as a ingredient. I been having a full cup full of store purchase kimchee lately because eof the ingredient list not listing and additives. _____ From: Heidi Schuppenhauer [mailto:heidis@...] Sent: Monday, 2 February 2004 2:04 PM Subject: Kimchi, was Jack LaLanne The Asian store kimchi has MSG, but otherwise it seems to be made like homemade kimchi, from the descriptions and the taste of what I've had. Except they don't put the " good stuff " in it (like pinenuts, seseme seeds, fish). Kimchi PRODUCES a lot of preservatives (it is being studied to come up with new and better preservatives for food) but as far as anyone can tell those preservatives don't hurt anyone. It DOES seem to keep " meat red " so there might be some kind of nitrate or nitrate-like substance produced from cabbage nitrates But nitrates DO seem to be reduced by any fermentaion, regardless of what they turn into. The link below talks about a lot of types of fermentation, but specifically nitrates are below -- Kimchi not only lowers nitrates, but any bad stuff like ecoli or salmonella (or whatever is in raw fish, listeria?). I think kefir has a similar effect, which is why I use it on jerky. http://seafood.ucdavis.edu/iufost/lee.htm On the other hand, most of the traditional fermentation methods have their own inbuilt safeguard mechanisms. The food infectious and poisoning microorganisms contaminated on the vegetables and other raw materials of kimchi are killed within one week of fermentation period mainly due to the acid formation and bacteriocin production (Lee 1997). Also, large amounts of nitrate and secondary amines in vegetable products are reduced by fermentation (Lee 1986). The importance of fermentation technology for the improvement of hygienic situation of needed region, where cold-chain system is not well established, was discussed at the FAO/WHO Workshop on the Assessment of Fermentation as a Household Technology for Improving Food Safety held in December 11-15, 1995, Pretoria, Republic of South Africa (WHO 1996). http://www.thebakersfieldchannel.com/health/1726017/detail.html The researchers found that the process of fermenting cabbage produces isothiocyanates, compounds that have been found to prevent the growth of cancer in animals, particularly in the breast, colon, lung and liver, they said. No one knows yet whether the compounds, which are not found in raw cabbage, have a similar effect in humans. Further studies are needed, they said. " We are finding that fermented cabbage could be healthier than raw or cooked cabbage, especially for fighting cancer, " said Eeva-Liisa Ryhanen, research manager of MTT Agrifood Research Finland. " We are now working on ways of optimizing the fermentation process to make it even healthier so that consumers will eat more (sauerkraut). " Evidence for sauerkraut's anticancer effect is growing. Previous studies have found that Polish women who move to the United States have a higher incidence of breast cancer than those who remain in Poland, which scientists attribute to a higher consumption of cabbage among the Polish women compared to their American counterparts. http://www.zongga.com/info_eng/e1101.asp Recently, the benefits of Kimchi has been published in a report, including its anti-aging and anti-cancer effects. Kimchi has many valuable substances that are beneficial to human health. We should preserve a variety of traditional Kimchi recipes to pass them down to our posterity. Here is an analysis of kimchi ingredients: http://www.kimchi.or.kr/english/make/source_prepare.html Methylmethionine,a biologically activated form of methionine found in chinese cabbage, helps treat Atherosclerosis Salted fish includes a variety of long-preserved fermented foods. During the fermentation period, protein is hydrolyzed into amino acid, resulting in a unique flavor. The bones of the fish turn into calcium, easily absorbed, and the fat turns into volatile fatty acid, providing taste. >Would this also cover you think kimchee bought at the asian store? > > : >>Does this mean the nitrates in kimchee are null and void? > >All the studies I've seen on kimchi (and kraut) indicate >that kimchi and kraut eaters have LESS cancer, and >that the cabbage ferments into potent anti-carcinogens. >Plus I read that nitrates are disabled in your stomach, >if you have enough stomach acid ... you would think >that kimchi has enough acid?

Guest guest Posted February 1, 2004 Report Share Posted February 1, 2004 If it is made in the States, they SHOULD list MSG if they add it. But ... glutamates are produced by kimchi-making. They don't seem to be BAD glutamates ... I get dizzy from MSG but not from kimchi (even commericial kimchi) though I may have gotten a migraine from eating too much of it (or not, I get migraines every so often, hard to tell why). I always assume Asian products have MSG, out of bias perhaps -- the old kimchi recipes DON'T list MSG, and it isn't needed. -- Heidi >Ah really.

Hmmm ... i'm guessing they were referring to *korean* radish, whatever that may be? similar to daikon, perhaps? do you use any radish in your kimchi, offhand? i use red radish which adds a nice zing. in any case, the study only found correlation NOT causation, so i wouldn't put too much stock in their findings.

They use daikon exclusively, as far as I can tell.. I've used red radishes too. I mix it with cabbage though -- most kimchi I've bought has radish OR cabbage, not mixed (that they could DO a study like that would seem to say there may be a personal preference for radish-style or cabbage-style, or it's a familial thing -- I've read that the bride is supposed to make the kimchi her mother in law mad and each family uses different recipes). >in any case, the study only found correlation NOT causation, so i wouldn't >put too much stock in their findings. Good point. I have read more about cabbage being anti-carcinogenic than radishes though. -- Heidi Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 2, 2004 Report Share Posted February 2, 2004 Is it possible that something got lost in translation and that radish = raddichio?

Well, Koreans do smoke a fair amount, eat a lot of char-grilled meat, and the guys drink a lot. None of which they mentioned. I would think THOSE are the carcinogens, and the people who don't eat the cabbage can't fight it off as well. But yeah, it probably is regional too, and that brings in all kinds of issues. I kind of doubt radish is carcinogenic though, it doesn't fit. -- Heidi Quote Link to comment Share on other sites More sharing options...
