Serious question:

We hear a lot about how phytoestrogens can skew our hormones and how we should probably avoid them.

But meat and dairy contain hormones, too, even if the animals haven’t been injected with extra hormones β€” just because all animals naturally have hormones, including estrogens.

Why are these animal hormones present in our diet, which are even more similar to our own hormones, not considered as much of a problem as phytoestrogens? Does anyone know how they affect us?

The only winning move is not to eat

I am unsure, my only real reference is a former coworker with an estrogen sensitive breast cancer tumor. If she ate/used products with any kind of soy or ate peanuts (those were the two big ones, she had lists and lists of foods) her tumor markers would shoot up. πŸ€·β€β™€οΈ

She didn’t have the same issue with dairy or meat?

I can't say 100% this was 20-ish years ago, I just remember soy was the biggest offender with peanuts coming in second.

I've generally heard that phytoestrogens are protective/less harmful than hormones found in animal products. Higher lignan exposure may reduce breast cancer mortality between 33 and 70 percent.

Interesting. I’ve never heard of lignan being a phytoestrogen. Gonna read this later

Also not all phytoestrogens have the same effect on the body. Phytoestrogens from hops, like animal estrogens seem to preferentially bind to alpa receptors, which can lead to increased chances of breast cancer and man boobs. While phytoestrogens from soy seem to preferentially bind to beta receptors which can have a protective effect, at least at low to moderate doses.

Interesting. This sounds worth looking into

We do? This literally the first time I've heard anyone mention phytoestrogens.
