Phytoestrogens are plant-based compounds that act like the hormone estrogen. There are two basic types of phytoestrogens: isoflavones and lignans.
Soy products are the most common source of isoflavones, and the controversy surrounding cancer and phytoestrogens are related to soy products.
Soy allergy can be diagnossed by a prick test or a blood test for immunoglobulin E (IgE) antibodies. Skin allergy testing is a method for medical diagnosis of allergies that attempts to provoke a small, controlled, allergic response.
IMHO, I would look for a Dr. who deals in allergies and request some testing.
I am sure others will be along to answer questions for you.
