A lot of us integrate soy in our diets with soy milk, soy sauce, tofu, etc. Did you know that soy isn't great for you? It is something I have most people avoid.
Soy is a phytoestrogen meaning it mimics the estrogen in our bodies. Since there are SO many phytoestrogens and xenoestrogens (these mimic estrogen too- things like pesticides, plastics, etc.) out there that our bodies are constantly getting bombarded by, it is best to be aware and limit your exposure. There are some great alternatives to your favorite products that contain soy. If you are drinking soy milk please ditch it and try something like almond milk or coconut milk. Also, never give any infants formula with soy or soy milk!
For soy sauce there is this great thing called coconut aminos! We love it at my house. It's a great soy sauce alternative and, honestly, I think it tastes better.
