    Another reason why "moderation" is a good philosophy.

    Does "processed" refer to nitates/nitrites? If so, some processed meats are made with celery juice or chard juice as an alternative.

    What about bacon with no added nitrates?

    Over 80% of dietary nitrates (in a diet that includes vegetables) are derived from vegetables and converted to nitrites by bacteria in our digestive system. Sources of nitrates include vegetables, fruits and processed meats. Nitrogen fertilizers and light intensity are the major factors that influence nitrate levels in vegetables. Organically grown vegetables generally have lower nitrate levels than do conventionally grown crops. Celery has a very high nitrate concentration. Nitrite is formed by treating celery juice with bacteria which converts the nitrates to nitrites used to cure the meat. These meats may be marketed as organic, natural, no preservatives/nitrates/nitrites added, etc. and other seemingly innocuous and comforting marketing phrases. Amines are naturally occurring compounds that are present in meat and human tissues and can react with nitrites to form nitrosamines, and it is these nitrosamines that have been linked in various epidemiological studies to cancer.

    Nitrites play a crucial role in processed meats. Meats treated with them acquire a characteristic taste, a reddish colour and a resistance to bacterial contamination, such as botulinum clostridium (causing botulism). Only the source of the nitrite has been replaced with the all natural vegetable juice cured meats. In conventionally cured meats, the levels of added nitrite are strictly controlled by regulations to minimize the formation of nitrosamines and minimize the risk of botulism. The levels of nitrites in vegetable cured meats are not regulated, variable, and less controllable, so you may be ingesting higher, the same or lower nitrite levels than those in conventionally cured meats. It's an individual choice as to whether you wish to avoid processed meats completely, or eat them in moderation. If you eat vegetables, you are consuming nitrates. The problem with epidemiological studies is attributed linkage. I have not looked into whether countries and cultures that traditionally eat diets higher in processed meats have a correspondingly higher rate of colorectal cancers, but will do so. Off the top of my head, I do not believe that Germans have a lower life expectancy as a result of a higher diet of cured, smoked and dried meat.

    They had an Oncologist on CBS This Morning talking about these latest findings.

    Everything in moderation, said he.  Don't eat bacon and bologna every day.

    Moderation sounds best. Even people who eat vegan or eat only organic find themselves with BC on this board. Someday they need to figure out why our bodies miss these cells that have reproduced erratically and haven't shut them down.

    What a bunch of crap that report is. I'm waiting for people who have eaten vegetarian to chime in here soon. We get more nitrates/nitrites in natural and fermented food than by eating bacon.

    So how many here don't eat meat and got breast cancer? Could they do some real research already? I guess since the included the word "CAN" in the title, that makes it good research?

    I'm headed off for a bacon sandwich myself. I'll put some avocado on there so I feel better about it.

    Just watched the ABC Nightly News report on the WHO's recommendation. You can all peel yourselves of the ceiling and step back in off the ledge now. The risk is for colorectal, not breast cancer. And here is the cold, hard statistical fact. About 8.2 million people worldwide per year get colorectal cancer. How many of those cancers are due to eating processed &/or red meat? Drum roll, please.......34,000! (Consider, too, that there are more than 7 BILLION people on earth). More perspective: a hypothetical person who doesn't eat processed or red meat has about a 5% chance of getting cancer over one's lifetime. A processed/red meat eater's lifetime risk? 6%. Get your colonoscopies as often as recommended (no polyps or diverticuli, every 10 yrs after age 50, every 3 yrs. after polyp removal) and you cut your risk even further. And I say this as the wife of someone who had a botched colonoscopy (a 1-in-2000 occurrence) but refuses to sue and still will get his done every 3 years (albeit by a different gastroenterologist). You could still get hit by a drunk driver, shot in a drive-by, fall off a mountain or have a fatal heart attack or stroke. A woman in a Chicago suburb who beat breast cancer was still murdered recently by her homicidal-maniac husband. Everybody has to die of something.

    Also bear in mind that though it's generally agreed that it's the chemicals in processed meat that makes it definitely (but mildly) carcinogenic, the study did not examine why UNprocessed red meat is, in its words, “probably carcinogenic." It didn't address the question of organic grass-fed vs. commercial feedlot-raised mammal meat, farmed vs. wild (e.g. game) mammal meat, nor even mammalian meat vs. red meat from fowl (duck breast, goose, ostrich, rhea). It hypothesized that cooking methods that employ direct (i.e., contact) heat such as grilling, frying or flame-cooking are probably more carcinogenic than indirect heat methods such as microwaving, baking, or “radiant" broiling (in which the flame doesn't touch the meat). But it didn't mention the specific chemical changes, other than the charring caused by the meat's sugars caramelizing (the Maillard reaction).

    Finally, remember this was NOT a controlled double-blind study (the kind that shaped how our cancers are being treated), but rather a retrospective epidemiological study that did not distinguish the red-meat eaters with otherwise healthy lifestyles from those who smoked, over-drank, and sat on their keisters most of the time. It merely showed a statistical correlation, NOT causation. We know FOR SURE that smoking or chewing tobacco and breathing asbestos particles causes lung or other epithelial cancers. That’s about it as far as absolute causation has been proven. If you smoke or chew enough tobacco, you WILL eventually get lung, throat or oral cancer. If you drink like a fish, you raise the risk of pancreatic, liver or esophageal cancer.......but cirrhosis of the liver or Hep. C will probably get you first.

    Still want to cut the risk from eating the stuff? Cut back, cut down. No need to cut out. Become a pescatarian or vegetarian for ethical reasons if you wish (maximizing food resources for the world, or animal welfare), but that will have no bearing on your own breast cancer.

    True, this study focused on colorectal cancer but of course we all extrapolate 😃. Whether this means anything for bc , is of course, unknown. I'm a great moderation proponent myself

    colon and breast cancer are connected in some way they can't really explain. My mom had both (and survived both) and that's how it was recommended I get my ovaries removed (because the ovarian cancer is also related to colon and breast cancers). So it might be a good idea to heed this. But I won't stop eating foods I love completely. Just less.

    Having breast cancer doesn't lower one's risk for colon cancer. As unfair as it may sound, i made come down with colon cancer someday.

    As for the nitrate free bacon...... I picked some up at Trader Joe's prior to my last camping trip. You can't go camping without bacon(I think it's a law?, or maybe a commandment?). The healthier(?) version just wasn't worth it

    . With Downdog's explanation, I'll never make the same mistake again

    only the real mccoy for camping trips from now on.

    Moderation ....just line drinking....is the key.

    The average person has a 5% chance of getting colon cancer; eating processed meats daily ups it to 6%.

    Never mind all the low-fat hoopla that swore no one would get fat or get diabetes and I still think it contributed to my risk (pre-diabetes) and breast cancer.

    They don't study genes or epigenetics; they look for a causal outcome and not double blind studies.

    Some genetic syndromes do increase risk for both colon cancer and breast cancer, such as CHEK2, but I can't imagine that has a whole lot to do with bacon.

    A little info about the organization behind these alarmist and sensationalistic headlines. The International Agency for Research on Cancer (IARC) is the specialized cancer research agency of the WHO. I am just going to drop this little tidbit about their raison d'être here and the focal point of their research, cut and pasted from the About IARC on their website, and use great restraint in not commenting on it. Emphasis is placed on elucidating the role of environmental and lifestyle risk factors and studying their interplay with genetic background in population-based studies and appropriate experimental models. This emphasis reflects the understanding that most cancers are, directly or indirectly, linked to environmental factors and thus are preventable.

    The IARC does hazard identification, not risk assessment. What they do is review and supposedly determine whether something may cause cancer, but not its potency, the degree to which it may cause cancer, or even relative levels of risk. From the IARC: Processed meat has been classified in the same category as causes of cancer such as tobacco smoking and asbestos (IARC Group 1, carcinogenic to humans), but this does NOT mean that they are all equally dangerous. The IARC classifications describe the strength of the scientific evidence about an agent being a cause of cancer, rather than assessing the level of risk.

    Not every exposure to a potential carcinogen will lead to cancer – frequency and intensity of exposure, as well as the potency of the substance all have an impact. The IARC has placed red meat in their 2A category, probably carcinogenic to humans, based on limited evidence. Their definition of limited evidence? Limited evidence means that a positive association has been observed between exposure to the agent and cancer but that other explanations for the observations (technically termed chance, bias, or confounding) could not be ruled out.

    Since 1971 the IARC has reviewed 982 products, substances and exposures – from plutonium to sunshine, from cellphones to sawdust and found that 981 of them posed a theoretical risk of cancer. The one exception was yoga pants, which begs the question, what kind of scientific rigor was employed by the review committee to actually approve the resources to study the potential carcinogenic effects of yoga pants?

    Well, I've been a pescetarian (only meat I consume is a little fish) since I was 13 (my personal rule of thumb is "don't eat anything you wouldn't hit over the head yourself"), and I got BC at 48. Then again, my mother gave me a bologna sandwich every day for lunch when I was in 1st grade! So, you never know...lol!

    ChiSandy, very interesting post. Where did you find those figures? I read a critique of the WHO report that they don't provide enough context on relative risk. They just throw it in the carcinogen pile and you have to figure it out yourself. I wish they would create a site where you could plug in the carcinogen and it would show you the additional cancers for high, med. and low use or exposure per every 10,000 users. That way you could figure out what is really worth avoiding. You also raise an interesting point about cooking methods. It could be the heterocyclic amines that are produced when cooking meat at high heat that causes much of the cancer. But you have HCA's in fish and chicken cooked that way, too. Hard to separate it all out.

    As a matter of fact, a friend of mine was arrested for bringing Turkey Bacon on a camping trip. LoopyIt must be PORK only according to the law.

    Also, I eat red meat infrequently but when I want steak, I want it grilled with the lovely char on it. Does this mean it caused my BC? Doubtful.

    Fallleaves, I got my figures both from Dr. Besser's (ABC's medical reporter) analysis of the WHO story on the Oct. 26 ABC World News Tonight, as well as a FAQ sidebar about the report in the NYTimes.

    Yesterday I was in Whole Paycheck (kind of relieved that my son had eaten my last portion of leftover ribeye, so I bought some jerk chicken), and noticed that the butcher was looking sort of bummed out. I asked him what was the matter, and he griped that he hadn't sold any meat since he went on duty a couple of hours before. I started reading the labels in the meat case and bought some nitrate-free bacon (partly to make him feel better, partly because I had run out of bacon).

    Nonetheless, I had anchovy pizza for dinner. (Now they're gonna tell us processed fish causes cancer). Meanwhile, that story has resurrected a pesky old earworm: Joe Jackson’s “Everything Gives You Cancer.” And Warren Zevon’s third-from-last album “Life’ll Kill Ya.” (At the very least, it’s a preexisting condition).

    He is most famous for Werewolves of London,, but that is far from his best song. And he actually didn't really like the song.

    I love the Spanish guitar on Carmelita,,, and Keep Me in Your Heart is a beautiful song. He was a really talented guy,, wrote all his songs, played guitar and piano,, his music ranged from hard rock to ballads. And the lyrics to Life'll Kill You,,,, are just great. Linda Ronstadt had a hit with Poor Poor Pitiful Me,, and that is one of Warren's songs,, on his first album. Yes, I'm a huge fan.

    When he was dying, he told his ex-wife to write his bio,,, "warts and all",, and she did. It's a great read. Gives you an inside on the rock music world in the 70's and 80's. The book is called: "I'll sleep when I'm dead" by Crystal Zevon. That is the title of one of his songs too.

    My first thought was, "Mmmm . . . bacon. I think I'll go have some bacon and high fat dairy."

    Belatedly, the WHO has issued a clarification. To access a MedScape article re same without registration, google the title:
