I have realized that even if you don't vaccinate your kids, feed them all organic food, cloth diaper, and breast feed, there are still many ways that they are exposed to chemicals and toxins outside of your control. It is easy to become so caught up in the natural and organic world that it becomes an unhealthy obsession. For example, if you can't go to someones house for dinner because you are worried they won't cook a healthy meal, you might have a problem. If you can't go out to dinner once in a while because all the ingredients on the menu are not certified organic, gluten, soy, and dairy free, you might have a problem. You laugh, but I actually know people like this! This is a life of fear, and while we do our absolute best at home, we are not going to let our health choices prevent us from enjoying life.
With that said, I am still astonished how willfully ignorant many people still are about nutrition. Food decides whether you are healthy or not. Disease and cancer feed off sugar, processed foods and GMOs. The science is there to prove it!
God gave you one body. Just one. Be responsible, not fearful.
