Soy is bad for you - high amounts of estrogen.

False actually. This study states that the isoflavones in soy don’t affect serum T levels. https://www.fertstert.org/article/S0015-0282(09)00966-2/fulltext https://www.fertstert.org/article/S0015-0282(09)00966-2/full...

That's not quite accurate. Soy contains phytoestrogen, which is a plant estrogen, not a human estrogen. It's similar in many ways and does have (in a much weaker form) some of the effects of human estrogen. However, just calling it "estrogen" implies that it's the same as human estrogen. It isn't.

  From anecdotal evidence it seems for some people the phytoestrogen still activates estrogen pathways. Probably has genetic variation on the effects.

    Anecdotal evidence? How does someone anecdotally detect that their estrogen pathway has been activated?

      By growing big moobs.

        then why is that not the case for countries with a significantly higher proportion of soy in their diets such as countries in Asia? if what you said is true then once would expect to notice it

        Like I said, genetic variation.
        evanextreme 6y ago
        so you suspect that some gene (evidence for which also exists "anecdotally") triggers a genetic response only in countries where this type of food isn't regularly consumed? because then this sounds like a wild guess prompted by suspicions and pseudoscience

As soon as I heard "man boobs" and "soy protein" I was out. This may be completely false, but truth is hard to come by these days. No need to risk it here when there are plenty of other good sources of protein. https://pubmed.ncbi.nlm.nih.gov/18558591/ https://pubmed.ncbi.nlm.nih.gov/18558591/

I dont have citations on hand, but my understanding is that this claim is largely attributed to a single/small amount of studies of dubious validity funded by US Beef industry, and that when you look at populations that have much higher soy intake, their estrogen levels are not elevated/are lower than similar US populations. Grain of salt and all that, just offering a lead for those curious of the counter argument

If that were true, we'd have seen significant effects in the peoples of Asia by now, where soy consumption is high.

Did you know that cow milk contains actual estrogen and other hormones?
