Careful with soy- it's not as beneficial as everyone thinks it is...

-soy is rated the second most allergenic food , the first being peanuts
-the soybean has a higher phytate content than any other grain or legume that has been studied. This is an acid that blocks the uptake of essential minerals in the intestinal tract. Furthermore, soy seems to be highly resistant to many phytate reducing techniques such as long, slow cooking.
-Currently the FDA is examining health concerns related to the levels of the toxin furan found in soy protein isolate. It is toxic and thought to be carcinogenic (meaning it can cause cancer).

I would suggest rice milk over soy milk.
