    The head of the cancer institute here told me that whole soy foods such as tofu are fine. It is the burgers, sausage links etc which are not recommended. I have never ever seen research so far that says whole soy foods have been studied and proven to put ER+ women at risk. I would love to see one if indeed they exist.   The only studies that show a negative impact use fractions of soy.

    Hi all:

    I am ER+ and have tried to avoid soy like the plague.  But, yesterday, when I attended the LBBC conference on advanced BC, both the nutritionis and the CAM onc said that 1) soy is almost impossible to totally eliminate due to its appearance in so many foods and 2) should make no difference to ER+ people if eaten in moderation.  I don't know if this helps anyone, or just muddy's the waters even further but that's the soy news that came out of the conference.

    And I have read that premenopausal women with the highest concenatration of genistin (sp) had the lowest cancer rates.  What seems consistent is that there is no evidence that fermented soy products adversely affects breast cancer in ER+ or ER- women  and it may be protective. If anyone can point me to any study which says whole soy (not the supplements and vegi burgers) has negative effects I would be most grateful.

    Thanks,

    Joanne

    Joanne- I would have to hunt around the house but there was an issue of the Utne Reader (last summer? I think) that focused on the "dark side of soy," particularly the potential problems with highly concentrated and processed soy products. You might also check the Dr. Mercola website which has some good info sometimes. I will see if I can find that issue of the Utne Reader.

    Robin- thanks for sharing re: the LBBC info-I don't think it muddies the waters further (they're already so muddy anyhow) - it's interesting to hear different opinions on this topic.

    I've been peaking into this topic since last summer. It seems there is no conclusive thought or study (of course), but it seems to me that ingesting soy will not pose any danger of aiding bc growth. I eat tofu at least once/week. It's a great source of protein fro me. I figure that moderation will be the key when there's uncertainty. I have read studies that illustrate lower bc rates for asian women who eat a lot more soy that we do. When they move to the U.S., their incidences of bc rise.

    I eat seaweed salads, brown rice & take supplements of COQ10, (great antioxidant propeller) Reish Gano and Cordyceps (mushroom extracts) & juice my greens daily. Fish, clean (friends raise it) meat, tofu & beans are my protein sources.

    It seems to me that cancer danger comes from multiple sources, diet being one of them.

    The best book on diet & cancer that I have found is Patrick Quillen's, How to Beat Cancer with Nutrition.

    happy spring!

    OH,

    I am with you. I hedge my bets. I eat some soy, not every day not every week, tofu, tempeh, yogurt. I drink almond milk and sometimes organic yogurt.  If only we knew. I do know the head of the cancer institute told me soy is okay and everything I have read says it is the fractionated soy (the junk they put in everything) that is to be avoided.

    I love your saying - "Why did the patient go thru treatment ?"  That is exactly how I used to think of the many surgeries, etc. Tomorrow I will be on the other side of whatever it was I was facing at the time.

    When we see those research papers they don't say how long the test ran for.  That's a large problem.  Genistein can and does reduce the size of a tumor.  In other research papers, after 13 weeks, the tumor came back with a vengence.  Unless they start telling us about the length of time they tested genistein and tamox together, we are still on our own.

    Hi,

    I was wondering if anyone had any information, about the Energy drinks like, Ensure or Prosure, I was reading the contents, and it does say, soy oil, soy  protein.  How much is not good.

    I appreciate any feedback on this.

    Thanks

    In my opinion any is not good. I avoid these products, especially the soy protein which is generally a highly processed form of soy. Same with energy bars, although I have found that Larabars and Clif Nectar Bars contain wholefoods ingredients only- fruits and nuts (also taste great!). I'm sure others will be along to comment soon and may be more specific regarding the "whys" of the processed soy protein being particularly a problem.

    Mem Sloan Kettering dietitian and my (pretty open-minded) chemo oncologist told me 2 servings of soy or flax is okay/week for ER+ women. But to be careful, in particular, of protein bars many of which have soy as their source of protein. 

    Btw, I had been guzzling soymilk the two years before my cancer developed. I have switched to a whey protein drink. 

    Sorry this isn't scientific or evidence-based! Just my two cents.

    I thought fermented soy a few times a week was okay - tofu, tempeh, miso.  I also thought flax meal every day was protective???

    Joanne 

    Here is one study I found cited on these boards.   Does anyone have any idea what is the best thing for us to eat?  If not, I wonder why is this so difficult to figure out.

    Hi there. I'm agreeing that it is NOT good to drink those soy protein drinks. Personally, I drink some milk, I eat yougurt and once in a while some cottage cheese. I try to eat & drink things with as few and identifiable ingredients as possible. I eat some junk sometimes, but try to eat as much broccoli as I can stand. I think sardines, salmon, tuna sometimes, tofu. tempeh, clean meat in small amounts are all ok; flax, broccoli cauliflower, cabbage, brussel sprouts, all veggies ( I avoid potatoes except sweet ones), berries are good, gren tea, white tea, water w/lemon. I've been enjoying moki for my sweet tooth. I get it at a large health food store & prepare & eat it with jams or honey or nuts - best nuts are: pumpkin, sunflower, walnuts. I also eat almonds. macadamia. I just started drinking citrus after being off it.

    Again, I can't say enough about Patrick Quillen's book, How To Beat Cancer with Nutrition.

    Most importantly for me, I feed my lions - and allow myself Ben & Jerry's once in a while, or some good dark chocolate or whatever junk my kids are eating that entices me. I try to feed my lions lest they consume me (and I would pig out royally).

    joanne-elizabeth, thanks for the appreciation about getting to the other side. I was feeling like I would never get there recently. But I met for a pre op with the Plastic surgeon today. I have to trust that his skills surpass his manner. I'm getting ready for the BIG mast w/DIEP surgery May 28, and as nervous as I am, I can't wait to get through it! After that, all I'll have is rads & then the bulk of treatments should be behind me - oh be still my heart!

    Allyson, yum to those compressed seed/nut bars. I love the ones with sesame, honey & flax. I can't stay away from those.

    These conversations about getting/being/staying healthy are so positively helpful.

    Thank you all!

    I agree with Mamnop based on what my naturopath told me.  I also do not eat flaxseed.  However, as mentioned by geebung above, I avoid soy but drink wine.  It would be nice to see the percentage of risk increase in all of these things.  If you read everything about what causes BC, you might go a little nutty.

    I missed this - what did Mamnop say about soy?

    I do read that a drink a day increases your risk however so I avoid alcohol. It is too bad they don't fund retrospective studies to put the soy/flaxseed controvery to rest.  Today I read they think black cohosh may be beneficial.  Ugh, every day a different theory.

    I just have to add my 2cents here. I am a thyroid patient with partial removal and I have been told by my endo to avoid soy because its a thyroid supressent and let me say that when I stopped eating soy I lost thirty pounds.

    Yes, this topic does get kicked around quite a bit. I think even the docs are confused. Some say soy is okay and others say to stay away from it. From my very own personal research, this is what I learned:

    Soy is a weak plant estrogen. When you eat soy, the weak soy estrogen "jumps" onto the estrogen receptor that your normal body estrogen would have taken. This knocks your normal estrogen out of its place, which, to me, is a good thing. This weak estrogen keeps the stronger estrogen from being able to access its "home". I would rather my body have the weaker plant estrogen than the stronger one produced by my body. I eat soy. My daughter, also a cancer survivor, eats soy. I eat raw soy beans for the genestine provides...which is a cancer fighter. I even create a handmade soy milk soap that I love. I am on the side of the docs who say it won't harm you, but we all have to make the decision we are most comfortable with.

    Hey cin!  Where've you been?  I haven't seen you in ages.  Was thinking about you just this week.  Love that serendipity. 

    <> I subscribe to the same theory you describe about the receptors and the plant esters being weaker than that of our own bodies.  ...but how does anyone know that the plant estrogens glom onto the receptors first? 

    <> 
    <>I really hope it's a provable theory that is correct.  I've found a soy butter substitute that I really like taste-wise and baking-wise.  I've avoided soy products for the most part, but now that I'm trying to get away from dairy products, soy is the dominant substitute.

    That is a good question. I think it comes from studying Asian populations who have very low bc rates.  I keep reading it is the fractionated soy that they put into everything from supplements to cereal to ketchup which is harmful to you, not whole soy which is in tofu, edaname  and tempeh.  A cancer nutritionist also said the Asians eat fermented soy such as miso and tempeh.
