Be careful with soy milk if you are on thyroid medication !!!Estrogen adheres to the same kind of protein that carries thyroid hormone and can compete for the site and thus make less of your med absorbed and available !!!! Since Soy has phyto-estrogens it possibly can work the same way !
Soy milk is not a healthy product anyway, unlike toffu and such since soy-milk is industrial byproduct of soy preparation. You might want to do some reading on the net before you become regular consumer of it - I know I would not drink it ... so just wanted to share :roll:
