Egan,

I think it's a matter of values.

If you have candida that is so bad that nothing can control it, yogurt can be a tremendous help. However, if you're trying to detox, milk prevents the excretion of mercury. This information comes from Dr. Boyd Haley speaking on this DVD:

We don't know why milk has this property, but it was very consistent in the testing Dr. Haley did.

Thanks.
