Soy = cancer fighter?

Study followed 444 women in China who had lung cancer. Lower mortality rate associated with increased soy consumption.

Study seems pretty legitimate from the article. I'm curious to read the actual publication.

Just something to think about...

  1. Just yesterday, a friend read to me out of an "expert" diet person's book saying that soy is one of the most allergenic and toxic things that should be stricken from people's diet. It makes me crazy when so many studies have such different findings.

      Definitely. Well that dietician certainly sounds like he/she is on the far end of the spectrum.

      I suppose it's like most anything else - moderation. I don't think you can go wrong that way.

    2. I'm always skeptical about studies. There are just so many variables that its hard to say that anything is definitively the case.

        And you can find a "study" to support whatever your opinion happens to be.

      2. Most of the stuff I've read about soy lately suggests that unfermented soy products (tofu, soy milk, soy protein powers, etc.) are not very good for you at all and should be avoided.
        No problem though, apparently, with fermented soy (such as tempeh, soy sauce, etc.)

          Hmm, I eat a lot of tofu, and wonder what could be bad about it. By a lot I mean we have it once every couple of weeks for dinner. I always thought I was doing something healthy for my family.

            You're probably fine. Don't quote me but I think cancer rates tend to be lower in Asian countries. And they've got much worse pollution.

              Soy is a phyto-estrogen, so it mimics the actions of estrogens. There is evidence to suggest that this can either be good or bad and effects differ for men and women. There is some thought in the scientific community that high levels of phyto-estrogens can interfere with testosterone's actions in men, but like most things, the results vary depending on the design and analysis of the study. The same goes for the effects of high amounts of phyto-estrogens in women and the correlation with cancers. The definitive answer is unknown, but I think you can rest easy if you eat soy once every couple of weeks.

                Thanks so much pollymerase. If we're talking tofu, it is no more than once a week, and even that is a busy tofu month.

                1. re: LulusMom

                  I think "a lot" of soy is every day or multiple meals per day. Your consumption sounds very moderate.

                    Thanks for the calming pat on the back Mel. I normally pooh pooh most of these kinds of studies. One day coffee is good for you, the next it is bad, but for some reason the very idea of soy being bad really caught me off guard.

          2. I remember similar studies back in the '80's indicating OJ would cure just about anything. I look at most of these headlines and think, "here we go again" and move on. If there si something to it. There will be further studies from some of the major instituions to back it up.
