Coffee and estrogen

I just read the study as well and I think this is good news all round for all coffee lovers!

gary null has said many times that coffee is extremely acidic. I've had three cups of it in almost 10 years. still crave it sometimes but never get around to making or getting any lately. a cup of st dalfour's organic darjeeling tea occasionally satisfies too.

wiki is notorious for castigating anything alternative, at age 71 Gary Null runs marathons.

he never says anything without studies to mention, he reads the medical journals and reports on them pretty much exclusively

so listen. the health stuff these days is very short fifteen minutes about, the rest politics, sometimes interesting. progressive radio network m - f noon est

Interesting topic, Claire. The abstract lists so many benefits of benefits of coffee. I notice that the women in the study were all Swedish, and I wonder if the results would hold true for other women of European descent. You mentioned Asian women -- is that from another study? The literature seems to be mixed and I wonder if there are different genotypes that respond differently to coffee. (It could be the case with soy as well. My former onc showed me a study that said soy is safe, but the study population was all Chinese women.)

In my case, all my adult life until bc treatment, coffee and chocolate caused my cyclical (hormonal) breast tenderness to worsen. I have fibrocystic breasts, and was told to avoid caffeine and chocolate. Sometimes I did and sometimes I didn't. On tamoxifen I did not experience the soreness, presumably because the drug was blocking estrogen in the breast tissue. (No soreness now either with permanent chemopause/menopause). Therefore, I think that maybe caffeine and chocolate are not good for me because they might stimulate the breast cancer cells, which are after all, my breast cells gone awry. I asked the oncology nutritionist about my idea and she had not thought of it, but said it was an interesting question. Any thoughts? That said, I do have coffee, caffeinated green tea, or chocolate occasionally, because darn it, I want them!

I'm not arguing any particular position here, just interested in the discussion.

The site http://foodforbreastcancer.com/foods/coffee

has a long list of studies regarding breast cancer and coffee. The article discusses genotype, fibrocystic breast condition, and other factors and concludes:

The Bottom Line

Based on the available evidence, women with benign breast disease should avoid coffee consumption. Moderate coffee consumption appears to be safe for most postmenopausal women, including breast cancer survivors. Drinking coffee may be beneficial for those undergoing treatment with tamoxifen. The potential risks of heavy coffee consumption appear to outweigh the potential benefits for most premenopausal women and it would appear prudent for them to limit coffee consumption. Coffee should not be consumed during chemotherapy.

We present these tentative conclusions for the many coffee drinkers who cannot wait until more definitive studies are published to decide whether to drink coffee. However, more research is needed to clarify the association between coffee drinking and breast cancer risk and prognosis.

Additional comments

Organic coffee is a better choice than non-organic coffee since coffee is often grown using high levels of pesticides.

I don't care. I've given up sugar and dairy and gluten and all prepared foods with artificial ingredients. I use only organic and safe beauty, personal care and cleaning products. I take a drug that gives me hot flashes and makes me constipated and rather miserable in a general kind of way. I am so NOT giving up my java. They can pry my coffee cup out of my cold dead hands!

Ok I found my answer here, I think it's from a separate study not related to breast cancer, but about coffee and estrogen levels.

Sadly...it does say that 2 cups of coffee a day for Asians increases their estrogen levels, and I am highly estrogen positive. With 3 young kids at home, I feel like I need to do all I can to rid estrogen from my body...I will do some more research about this to see if I can find out more, but for now bye bye coffee 🙁.

Have an extra cup for me ladies 🙂, and thanks again Claire for bringing this to my attention!

It is just one study...small sample 250, with young participants 18-44. So keep that in mind...

That being said...for me I'm choosing to give up coffee for now...until I can find out whether it is beneficial or harmful to me.
