Wrong consumption may develop risk of developing food borne disease for you as well as your unborn child.

Consuming soy milk during pregnancy may provide folic acid, vitamins, proteins, and other nutrients. These nutrients boost your energy levels and help better develop the fetus. However, it is important to consume soy milk in moderation because excess of it may elevate the estrogen in the body, increase the risk of defects in babies, and trigger migraine headaches. Therefore, it is recommended to consult a doctor before consuming soy milk during pregnancy, especially if you have never consumed it before and want to introduce it while you are pregnant.
