No, Soy is not dairy b/c it comes from soy beans, not a cow. Now soy milk is very good for you, but be careful b/c some people do have an allergy to soy. I also read that too much soy in your diet can mess with your thyroid...(it could just be one of those BS studies like cell phones giving you cancer) but you never know. Make sure if you buy soy milk that it isn't loaded with sugar b/c sometimes they add sugar b/c plain ol soy milk tastes like crap. If it tastes real good, there is probably a lot of sugar in it.
