Aren't some diseases communicable through human breast milk? I know that's how many babies get HIV from their mothers. Not sure if pasteurization of the milk would fix that or not.
I drink mainly soy milk. Use it in my coffee and when eating cereal. At first it tasted funny to me but now I actually prefer soy milk to cow milk. I still eat dairy products though, such as cheese, sour cream, and ice cream. I'm pretty sure I have the mutation.
Ideally I'd like to cut out dairy and eggs in my diet for ethical reasons.
