A: Because of the complexity of your case, I would highly recommend you meet individually with a registered dietitian who can help outline a personalized nutritional plan to best meet your needs while taking into account some of your limitations. The data regarding phytoestrogen intake with hormone-sensitive cancers such as yours continues to evolve. What seems clear at this point is that dietary supplements containing phytoestrogens should be avoided - so I would applaud your adherence to this restriction. More study is needed to determine to what degree naturally-ocurring dietary phytoestrogens (such as those found in soy foods/beverages) affect the cancer. It sounds like you're currently consuming at least 3 servings of soy foods per day. Most conservative recommendations would suggest limiting consumption to 1-2 servings daily until more is known about this controversial topic. Beans/lentils/nuts may be a healthy alternative to some of your soy products as these provide protein similar to soy and they should not interfere with your food intolerance.
