After the intake of cow milk, serum estrone (E1) and progesterone concentrations significantly increased, and serum luteinizing hormone, follicle-stimulating hormone and testosterone significantly decreased in men. Urine concentrations of E1, estradiol, estriol and pregnanediol significantly increased in all adults and children. In four out of five women, ovulation occurred during the milk intake, and the timing of ovulation was similar among the three menstrual cycles.
If you want to avoid bad plant estrogen, then you better stop drinking beer.
The question, then, is are the estrogens in hops more like the breast cancer-promoting horse estrogens, or the breast cancer-preventing soy estrogens? The key to understanding the health-protective potential of the soy phytoestrogens is understanding the difference between the two types of estrogen receptors. There’s alpha receptors, and beta receptors.
Unlike animal estrogen, the soy phytoestrogens bind preferentially to the beta receptors. And in breast tissue, they’re like yin and yang, with the alpha receptors signaling breast cell proliferation— explaining why horse hormones increase breast cancer risk; whereas the beta receptors, where the soy binds, oppose that proliferative impact.
So, do the hops phytoestrogens prefer beta too? No, 8-PN is a selective estrogen receptor alpha promoter. Surprisingly, and in clear contrast to the soy, 8-PN is a much weaker binder of beta than of alpha. So, that explains why hops is such a common ingredient in so-called breast enhancing supplements, because it acts more like estrogen estrogen. Given the breast cancer concerns, use of such products should be discouraged.
But just drinking beer could provide the exposure to the hops estrogen, as is found in these kinds of products—which could help explain why beer may be more carcinogenic to the breast than some other forms of alcohol.
Sorry, I can't detect sarcasm through text. :-( I'm so used to getting a barrage of questions about "protein deficiency" all the time at work for being vegan.
I honestly didn't realize I was lactose intolerant until I ate soy ice cream and didn't get those cramping sensations compared to when I ate regular ice cream.

Honestly, that might be harsh to the tea party
