Re: Coffee and Tea
My understanding is that the estrogenic qualities of coffee are not related to caffeine. So decaf or reg would have the same issue. I saw this first in relation to promoting an existing ER+ breast cancer (at surprisingly low levels) and more recently in prostate cancer, where there is a benefit. Makes sense since prostate cancers, driven by androgens, are sometimes given estrogenic supplements to help fight it. To complicate things, there are some instances in breast cancer tha have been deprived of estrogen can become susceptible to highly estrogenic supplementation..i.e estradiol shots etc. The trick is knowing when the ER+ cells have jumped ship and become vulnerable to estrogen. Who knows. But if you are in the mode of treating the cancer by blocking or reducing circulating estrogen, probably counterproductive to drink coffee.
