We know there has been a bit of a movement away from traditional dairy milk, but trust us on this one, soy milk is not going to make things any better for you. We've already talked about how most soy products are GMOs and have been linked to cancer, but soy milk in particular carries an even bigger risk. Due to the natural estrogen in soy, it can cause breast cancer to develop and grow. It can also cause existing cancers to grow at a faster rate.
Some studies have even suggested that soy products can actually turn on genes that can cause cancer. All in all, it's a pretty dangerous prognosis and we highly recommend stepping away from the soy milk. If you're really set on giving up dairy, try a more natural nut milk, such as almond milk or cashew milk instead.
