1. For some people is does. I don't think the answer to this is clear, different sites say different things.
   
   It is a food known as a goitrogen. There are more foods in this group such as broccoli. I think it is up for debate whether this effects healthy people with proper iodine consumption.
   
   I am going by memory, I'll give a link.

   Goitrogens work by interfering with the thyroidal uptake of iodine.

3. According to several articles, soy products contain isoflavones and researchers have identified that the isoflavones act as potent anti-thyroid agents, and are capable of suppressing thyroid function, and causing or worsening hypothyroidism.
   
   This article in particular was very interesting and has links to other articles and books:
