Soy not so smart for lowering breast cancer risk





NEW YORK (Reuters Health) - At least one third of women at high risk for breast cancer regularly consume soy-based foods -- but this may not be a good idea, researchers say.



While the benefits of soy consumption for cardiovascular health have been confirmed, there is no evidence that soy foods improve breast health, particularly in non-Asian women, Dr. Carolyn Y. Fang of the Fox Chance Cancer Center in Cheltenham, Pennsylvania, and colleagues note.



In fact, they point out in an article in the Journal of the American Dietetic Association, there is some evidence that high soy consumption could actually increase breast cancer risk among US women.



Fang and her team interviewed 452 women with family histories of breast cancer about how frequently they consumed soy and why.



Forty-three percent of the women had consumed at least one soy food in the past month, while 32 percent defined themselves as soy consumers. Soy consumers ate 18 servings of soy each month, on average, most commonly vegetable burgers, tofu, soymilk, soy nuts and green soybeans.



Women characterizing themselves as soy consumers were more educated and more likely to eat five or more servings of fruits and vegetables each day. The most common reason for eating soy, they reported, was to have a healthy diet. Forty-five percent said they believed soy foods reduced cancer risk.



Among the women who did not eat soy, 7 percent said it was because the plant estrogens in soy foods could promote breast cancer, and some said a clinician had instructed them not to eat soy foods for this reason.



"Given that high levels of soy intake might increase breast cancer risk, our findings highlight the need for clear, consistent messages regarding the health benefits or risks of consuming soy foods, particularly in the context of cancer risk," Fang and her team write.



They note that women who believed soy had cancer-preventing properties were less likely to have gotten their information from health care professionals than women who didn't consume soy because of a potential cancer link.



"Thus, health professionals should take an active role in communicating and clarifying such information to patients, consumers, and public information/media channels," the researchers write.



"The message...may simply be that we do not have enough information yet to make an informed judgment. Be that as it may, consistent health messages from all sources should help to prevent further misinformation," they conclude.

One article such as this wouldn't freak me out by itself. I would need more info about this. You also need to know who payed for the study, which is always important. Also, check results with larger studies before making up your mind.

I've been to Cheltenham. It's ecosystem has been so severely sacrificed that I doubt it's a clean slate for any scientific testing.

Diana 10-07-2005 01:50 PM

Trouble with this kind of article and research, there'll be another one coming along in a year's time saying the exact opposite.



It's something to keep in mind, but more research would have to be done for it to persuade me.



Reminds me of the old saying which says that all murderers and rapists ate sugar in their childhood, therefore sugar is most likely the culprit for their bad behaviour.



But I do think that there is a lot of stuff about soy which we are not aware of and that it may not be as healthy as we think it is. I always feel a bit uneasy somehow when I eat the stuff.

If you thought that was bad .





Flaxseed oil, olive oil , nut oils stimulate cancer cells in Prostate and Breast.

I think it is also very important to look at who the study was done on.

I mean for a simple compairasin lets take milk now I know most people here do not drink it but stay with me a moment.



Milk contains a sugar called lactose basic stuff we all know this.

We also know that most adults lose the ability to digest this sugar with or without symptoms like gas, bloating, stool problems which are the indicator for most people to say "I'm lactose intolerant" the number of lactose intolerant people is much higher.



Why you might ask?



Well American Indians,Asian,Afrian, decendants are mostly lactose intolerant but people of European ancerstery often are not.

It was an evolutionary thing, were milk was a mainstay of survial adults retained the ability to digest milk properly.





Whats this got to do with soy?

Well in studies of Asian women soy shows almost nothing but good results.

But take a woman like me who is of Italian,American Indian, scottish and African American heratige, soy messes me up something bad in fact cuting it out of my diet compleatly was the only way to stop some of the unbearable pain of endo, now before you say I'm mental untra sound also showed a significant improvment.

My doctor says it is the first thing he advises women with Endo to discontinue soy from thier diet because it almost always shows an improvment once soy is gone.



Point is you can do all the studies you want on food but unless you do an extreamly in depth study seperating people little by little you can not be sure on what the risks/health perks are.

I agree..



Am I the only one who noticed they said Asian Women were fine with soy? Think long and hard about this .... Couldn't this be because they do not eat red meat? I really don't put any stock in medical studies, because they NEVER study people with my background, diet and lifestyle. Adding one good thing (soy) to your carcinegenic, toxic lifestyle (junk, no exercise and meat) is not going to take away your risk factor.



"Drink the Soy, It's good for you!!"

umm now I'm just sayin we are a military family but all the asian women I have ever met eat red meat. They eat fish more but they do eat red meat back home it seems they like all parts of it to and I do mean all parts

It's also the Asians that have a raw beef dish, right?



I try not to take these studies to heart. Everything causes cancer and/or prevents it.

I'm sure Asian women also are not eating a lot of soy meat analogues and soy isolates (like protein powders and soy in protein bars) as Americans tend to do. I think the more processed the soy, the harder it is on a body. Soy gives me and my family tons of gas so we don't eat much of it at all, and I prefer almond milk.

You are right they do not, they eat mostly fermented soy, not all the seperated and processed stuff
