Soy products have shown to cause soy allergic reactions in some people. Soy has long been known to cause increased phlem production so if u r using soy milk and other products and have more congestion, it may be an allergic reacton.
If you take thyroid medication, soy products may block this medication, thus requiring you to use more meds.
So in a nut shell don't just take soy without these considerations
