Relieving Yourself of Excess Estrogen – Dietary Habits For Breast Cancer Prevention


Vegetarian Diet Helps Prevent Breast Cancer By: Michael Greger, M.D., a physician, author, and internationally recognized professional speaker.

Earlier this year a study was published comparing the hormonal levels of women with and without breast cancer. If estrogen makes most breast cancers grow, then one would expect that the levels of both estrogen would be higher in women who have breast cancer compared to women who don’t, or at least who don’t yet.

And indeed, no surprise, that’s what they found, significantly more estradiol freely circulating through their bloodstream of those with breast cancer. But the study also looked at diets and hormonal levels. These were all omnivores. The women eating vegetarian did even better.

This may help explain why, in a study of the “relative risks for breast cancer by levels of animal product consumption”, there appears to be a trend between lower breast cancer risk the more vegetarian someone eats. And it was researchers at my medical alma mater Tufts that figured out why, in a landmark article published in the New England Journal of Medicine.

See, the way your body gets rid of excess cholesterol is to dump it into the digestive tract knowing full well that there will be lots of fiber in there to grab it, hold onto it, and flush it out the body. (hopefully you chew a little better than that).

We did, after all, evolve quite a long time before Twinkies and Wonder Bread, and royal institutions such as Burger King and Dairy queen. So our body just expects it. It just assumes our intestines are going to be packed with fiber all day long—7 times more than we’re getting now. We certainly did evolve eating some meat, but plants don’t tend to run as fast and so the bulk of our diets was made up, of a lot of bulk.

And that’s how our body gets rid of excess estrogen. Vegetarian women have increased fiber input, which leads to “vegetarian women having an increase fecal output, which leads to increased excretion of estrogen and a decreased blood concentration of estrogen.”

And this just wasn’t in theory, they measured it. “Subjects were provided with plastic bags and insulated boxes filled with dry ice for thee 24 hour fecal collections.” You’ve hear of popsicles, well they had them make more like, poopsicles.

And here you go: In any one 24 hour period, the vegetarians were fecally excreting more than twice as much estrogen as the omnivores.

And, measuring the estrogen excretion versus the size of the fecal output, you can see, the bigger the better. See heavyweight V’s versus the welterweight Os? No wonder vegetarian women in the United States have been found to have such lower rates of breast cancer.

It’s great that many women stopped HRT, stopped taking extra estrogens. Well, another way to rid yourself of excess estrogens is in the way nature intended.
