Research suggests the common table mushroom has anti- aromatase  properties and therefore possible anti-estrogen activity. In 2009, a case-control study of the eating habits of 2,018 women in southeast China revealed that women who consumed greater than 10 grams of fresh mushrooms or greater than 4 grams of dried mushrooms per day had an approximately 50% lower incidence of breast cancer. Chinese women who consumed mushrooms and green tea had a 90% lower incidence of breast cancer.  However the study was relatively small (2,018 patients participating) and limited to Chinese women of southeast China.
We already discussed what happens in your body while you sleep. The good news is, you can help to prevent the muscle breakdown that normally occurs with the help of the slow-digesting protein casein. Just be sure the casein you choose lists micellar casein first on the ingredients list. This is the slowest digesting protein you can get; it takes a good 7-8 hours, providing your body a slow and steady stream of amino acids all night long. Your body will use these amino acids for fuel instead of breaking down the aminos from your muscle fibers. Also, get in one final dose of fish oil at this time. Fat will help to further slow down digestion rate, and the omega-3s will provide a host of other health benefits.
Aromatase inhibitors tend to cause fewer serious side effects than tamoxifen, such as blood clots, stroke, and endometrial cancer. But aromatase inhibitors can cause more heart problems , more bone loss ( osteoporosis ), and more broken bones than tamoxifen, at least for the first few years of treatment. If you and your doctor are considering an aromatase inhibitor as part of your treatment plan, you may want to ask your doctor about having a bone density test to see if a bone strengthening medicine might be necessary while you're taking the aromatase inhibitor.
