Interesting for those of us using soy products. Scroll down to ‘conclusions’ for the bottom line…

While estrogen can be a problem if you have BRCA2, If you don’t, then it is actually a benefit if used in high doses. If you are to take estradiol instead of ADT for Reducing testosterone levels the estradiol at least keeps some of your sexual desire active unlike ADT. It also has many fewer side effects than ADT.

Dual Action: Estrogen can have a dual role, acting as a potential promoter of early cancer development, but in some clinical scenarios, high-dose estrogen has been used to treat advanced prostate cancer by lowering androgen levels.

A search AI says this
Soybean products do not produce high levels of human estrogen in the body. Due to their weak nature, they often have a protective, anti-estrogenic effect rather than a boosting

I’m wondering, where are you found that estrogen creation is a problem with soy?

@jeffmarc It’s a long perpetuated myth, Jeff, and even the science does not support these long held beliefs.
I posted an article to Bobgolf on this topic.

@jeffmarc it sounds like I was caught up in some negative hype about soy products from years ago. Thanks for the new more current views!

Bob, check out this article; plain speak and very supportive of soy if you enjoy it.

@heavyphil thanks! it sounds like I was still listening to some old theories from the past. I'm really not a big fan of the taste of soy, but its good to know I don't need to stay away from products that do contain soy.

My radiation oncologist suggested I take soy isoflavones to help with my hot flashes. I still get them but I don’t think they are as bad as before. I’ve been on Lupron since December of 2024 and have 10 months left.

The type of estrogen in soy is a plant based one, so I have read from NutritionFacts.org, so cancers are not enhanced by its use.
I use soy and almond milks, sometimes oat in my cereal, find the Silk brands to be the best tasting.
The big takeaway from using soy products is what we are not consuming regularly- that we can replace the potentially dangerous cows milk and dairy products for just about all things we like to eat-cream cheese on bagels, sub. parmesan and gouda for sandwiches, etc. The only cheese that I cannot find to successfully trade out is mozzarella for our occasional pizzas.
Study out of the Scandinavian countries found that for every 8 oz. glass of milk consumed by middle aged to senior citizens, the fracture percentage climbed about 10%!

That was an extra glass of milk per day.
