for those wanting something a little different than soy milk, i really like EdenBlend, which is a mix of soy milk and amazake (a brown rice milk) along with some seaweed nutrients.
all of Eden soy milk beverages seem to have seaweed nutrients, which is really good for you.
one of the dangers of soy is that too much for males will begin to turn testosterone into estrogen or something to that effect.....but you will have to completely eat a lot of soy - or maybe that is tofu!? i know one of those two has that effect on the male body if you have too much of it.
