I just got finished reading your post on the Ask Cathe forum about soy isolates and concentrates. First off I want to say that my mom had breast cancer related to her estrogen levels and she was big into soy. She ate the veggie burgers, drank soy all to avoid the chances of her getting cancer. As I was reading that post to her we were completely taken back by the fact that she thought she was doing the right thing but in essence she was eating mostly isolates and concentrates. I'm sure there were other factors regarding the cancer. I'm not saying that is the only thing, but I for one avoided soy all together. So I thought until tonight. I have been eating the morningstar burgers and such now for a month thinking I'm doing somthing good for myself. She was doing the same thing. I never realized the differnce in the soy ( tofu) and soy isolates. I just want to thank you for pointing this out to me. I have heard so many mixed issues in the media concerning soy and now I can see I don't have to elimate the soy milk that I enjoy just the soy isolates and concentrates. I just wanted you to know how much you helped me. Here I am thinking I'm doing the right things by eating veggie burgers when in essence I'm repeating history instead of helping my chances. You are completely right when you say people think they are eating clean when they truly are not. I just got finished throwing out all my burgers and such. Can I ask you that when looking at a food lable, will it just say soy protein and that is it? That is what I should be looking for. Am i correct. I have been eating a vegetarian lifestyle for about two months. I realize now I should avoid the burgers. Anyway I just want to say thanks. From my mother and I. Karen

Karen, not Kathryn here, but I just wanted to say that I looked at your picture trail and WOW!!! You look amazing! Congratulations on your weight loss. You're an inspiration to us all!

Thanks so much to the both of you. Being overweight for so long and then losing it you feel like a different person. It really is so much about being healty for me. Breast cancer is so in my genetic make up I had to do somthing to decrese my odds. Not that weight would give me cancer, but you know what I mean. I had to help myself. Thanks for the compliments ladies. It's snowing here in Maryland and I'm checking email and you both made my night. karen
 
You know, there are studies that show that women who workout are less likely to get certain kinds of cancer (breast and ovarian included). But also if they get cancer are more likely to survive than those who don't workout. So keep up the good work!!

Glad I could help!
I, also was confused about the mixed messages about soy: populations eating it showing benefits vs. studies showing increased risks of some cancers, until I figured out most of these studies used, not soy FOODS, but isolates or concentrates (I'm not sure which, but avoid both most of the time).

I've give up soy protein powders for this reason (and instead use pea or pea/rice or brazil nut protein or hemp--hemp being my prefered, because it is a whole food with a very assimilable form of protein).

As for labels, they will say "soy protein isolate" or "soy protein concentrate" or "isolated soy protein."

I'm not sure where TVP sits here, because it's made from defatted soy flour (so just some fat removed, which seems better to me).

A company called www.dixiediner.com has meat analogs made from soy flour (powdered soy), and their web site has information about soy's health benefits (they might even have info on some of the studies showing soy is 'bad').
 
Karen,
I also did not know there was a difference until I read a post by Kathryn on soy a while back. Her information was invaluable to me as well:)

Just a belated "Thank you," Kathryn.......

Would one of you ladies mind posting the link for the original post you're referring to? I looked a little bit, but can't find it.

I've recently switched to fat free soy milk and I also eat the Boca brand burgers, chicken patties, sausage links, and chili (not too often, just when I make my kids hamburgers, hot dogs, etc). I've always been hesitant to go this route...I have always thought that they take out the 'bad' stuff and put in something 'not as bad, but not all that good for you either'. Does that make sense? LOL

Anyway, I'm VERY interested in what you guys are talking about and would love to check out the info on the isolates and concentrates, etc.

THANKS!

Gayle I don't know how to post a link but I can tell you where to go. It's in the Ask Cathe forum under the heading Eating "Clean" Splenda. Karen
 
Here is one study that shows that shows that it has no different effect than beef protein. Just found this to interesting. Once again I think everyone should research this for themselves and come up with their own determination and not go on what just one person has to say about it. I know that I am researching it myself before I come to the decision to discontinue the use of it. :)

The picture is also unclear when tumors rather than ACFs are used as the end point. In an early study, soybean protein did not differ from beef protein in terms of relative numbers of colon tumors in DMH-treated rats [19]. Defatted soybean meal was not protective in the same model [20]. However, we previously reported the protection afforded by lifetime-feeding of a soy protein isolate, against colon carcinoma in AOM-treated male Sprague Dawley rats [21]. Dietary genistein, on the other hand, had no effect on colon adenocarcinoma incidence or multiplicity of invasive colon carcinoma, yet actually increased noninvasive and total adenocarcinoma multiplicity [22]. In contrast, soy protein isolates with two levels of total isoflavones did not elicit differences in colon tumorigenesis in the Min mouse model of intestinal cancer [23]. However, feeding of a high molecular weight insoluble fraction from proteinase-treated soybean protein isolate suppressed colon tumor numbers in rats [24,25].
