I stopped drinking Blue Diamond Almond milk a few months ago when I learned of this carcinogenic additive they put in their almond milk: Carrageenan.
I may even start making my own nut milk because it is so easy and you can sweeten it anyway you want! With stevia, dates, vanilla, chocolate--the possibilities are endless! Max Goldberg from one of my favorite blogs, Living Maxwell, has a video showing you how to make it
While we are on the subject of dairy alternatives, I recommend staying away from soy milk all together. Even if it is organic (therefore, non-GMO), studies have shown that soy raises estrogen levels in the body which has been linked to breast cancer in women and in some cases causes men to grow breasts!
NOTE: Silk Pure Almond Milk also does not contain Carrageenan, but I personally refuse to support them because they are one of the many companies paying money to attempt to keep GMOs from being labeled. (You can read more about it here)
