Women with estrogen dominance as well as those who suffer from menopause problems whose diets are high in saturated fats, such as butter and dairy products (especially cheese and ice cream), often stimulate the growth of unhealthy, anaerobic bacteria in their intestinal tract. These bacteria chemically change the breakdown products of estrogen into forms that can be reabsorbed back into the body.
These bacteria split estrogen from the binding substances that inactivate it in your liver. This splitting process causes free estrogen to be reformed within your intestinal tract. As this free estrogen is reabsorbed into the circulation, it increases free estrogen levels within the blood.
To suppress the growth of these unhealthy bacteria, you should not only reduce your intake of saturated fat (which can lead to the problem in the first place), you need to increase your intake of probiotic-rich, fermented foods so you can recolonize your intestinal tract with healthy bacteria. These include yogurt (preferably goat- or coconut-based), kim chee, pickles, and sauerkraut.
