I just came across this report and thought I'd share it out here.  Personally I've no position on soy, but thought it was a relative subject for HW:

I am not surprised at this finding, this has been in the news before, thanks for posting it

Good info, although it sounds like this study was a little flawed. I have tried to like soy, but just can't bring myself to tolerate it other than edemame in a salad.

Yep Purg, I figured there had been other studies out there, wasn't sure though and thought I'd throw this one out as another piece of information.

Mike, I didn't do a deep-dive on the study but it wouldn't surprise me if there were some flaws in it - it seems awfully tough to find a study that's bullet - proof! Like I stated earlier, I've got no position on it, and quite frankly the very few times I tried soy products, yuck!

While I don't like or use soy milk or soy products, I do like the Almond Milk with cereal. Only in the past 6 months, it seems like I am becoming lactose intolerant. Never was an issue before. Now anytime I eat ice-cream, or use real milk, it makes me sick as a dog, with severe stomach cramps and diarrhea.

So I now avoid all milk products.

When I gave up cow juice I started with the Silk milk. Pretty nasty stuff, but I persevered and managed to tolerate it with my morning cereal. My wife found chocolate Silk one day and bought a half gallon for me. I wasn't sure about that and it stayed in the fridg for a couple of weeks before I broke down and poured it on the corn flakes. Say, that's not half bad.....so now that's all I use.

Don't get me wrong,....it's not as good as good old chocolate milk, but its a passable substitute.

I eat a lot of tofu and the rare times I do eat cereal I prefer fat free milk or soy or rice milk. I also use egg beaters and drink diet drinks.  do they taste better?  I say eventually they do.  try drinking a regular coke after drinking diet coke for years.  terrible right?

After my RRP I needed to lose a lot of weight so I used the Medifast program which uses Soy based protein. I have had little other protein since last October. Just glad study did not show adverse effect with soy protein.

I don't know if many use soy to halt PSA rise. I simply use it as a substitute for red meat and dairy products which some research indicates should be limited by those with prostate cancer.

I've found some fairly good soy based products for burgers or hot dogs. I've found that once you load them with all the accessories such as fried onions, mushrooms, tomatoes, mustard, etc. they make pretty good substitutes. There are some that mimic Italian and other types of sausages. In fact, my youngest daughter who is not a vegetarian, started eating the veggie-dogs just because she likes them better than regular hot dogs.

Soy milk isn't great straight, but not bad blended with a frozen banana, a few frozen cherries and a teaspoon of cocoa. In fact if you make a fairly thick blend of this and a little whey protein, you can get a pretty good ice cream substitute. I also usually drink soy milk in my coffee, but I have to admit that it doesn't beat real milk.

Dreamerboy,

Excellent point!

For me, it was a switch from obtaining protein from red meat to obtaining protein from soy and vegetables. Based on my readings, I saw red meat and dairy as the problems. I did not see soy as a supplement that would treat PCa ... I saw it as a perferable protein source.

It would appear that this study administered the soy as a supplement that was somehow supposed to treat the PCa ... without decreasing the consumption of red meat.

I'm still not sure the soy has helped me with regards to PCa but my weight and cholesterol are down and I am still in the zero club, so I continue it's use.

Gotta try your frozen banana smoothie with cherries and cocoa. I've been making breakfast smoothies with soy milk, bannanas, strawberries and soy powder (thickener) ... but cherries and cocoa really sounds good.

My wife and I have used whey protein in the past, but I'm going to avoid dairy now, with the exception of pizza once in a while.

I've stayed away from red meat for over 35 years, so that's not a problem for me. We both like black bean burgers and Boca burgers. The tofu sausages we get aren't bad, either.

I've been wondering about the soy protein and I may go ahead and start that for protein supplementation. It doesn't matter to me if it treats PCa, as long as it doesn't make it worse.

Highly recommended, unsweetened almond milk, it's a very good milk substitute w/o animal growth hormones, antibiotics and whatever else the cows are pumped with to get them to produce more milk, faster, for less.

Since avoiding red meat is generally a good habit for all including non-cancer folks, I do a lot of tofu and fish. Tofu as a source of protein works quite well in stir-fry and soups as it acquires the flavor of whatever you are cooking. Not a big fan of vegi-burgers. Might I also suggest quinoa (grain) as another protein source. Its not the easiest thing to eat prepared just by itself (resembles cream-of-wheat) but I imagine it could be added to other recipes.

Yooper,
The study is interesting. It focuses on high risk cases of PCa but not on low or intermediate risk cases. This does not make soy substitution for Omega 6 fats a bad option at all. I am a proponent of healthy life style changes for one huge reason pointed out to me by Mark Moyad, a renowned integrative oncologist. It likely to help a man with what is more likely to kill him.

I am not surprised by these findings at all. Since most high risk cases will not die of prostate cancer, the soy diet is probably not hurting a patient and helping elsewhere.

Thank you for this post.

Tony

Thanks Tony - yeah, I hesitated to put this thread out here as the study could indeed be 'flawed' depending on how you consider the data. It also doesn't say soy is "bad" for PCa but rather challenges whether it can put the brakes on PSA increase or not.

At the end of the day I decided to put it out here as kind of a "FYI" - and, as you mention, soy is still a good option for protecting the ticker!
