Here's what we actually know. In the U.S., more dairy in the diet -- of whatever variety -- is generally associated with better health and weight outcomes.

In global context, some of the world's healthiest diets and most convincing intervention trials have de-emphasized, or even excluded dairy.
There is a point at which invoking personal responsibility to deal with a contrived array of obstacles is both benighted and callous. Yes, everyone should try to eat well -- but they should not have to overcome the ingenious manipulations of highly paid mercenaries conspiring against them to make it so.

So far, I have kept the faith that eventually enough data would rally us to common understanding and common cause.
