I don't see them going away either, but I think that it's important that the public realizes that they are completely optional for good health.

But there is this perception that they are absolutely essential due to decades of dairy industry advertising and lobbying, and it's simply not true.

They're not absolutely essential, but they are very nutritious, which is why the lactose tolerance gene has been so heavily selected for.
