The chef's caveat

Plain vs. flavored

Numbers on this page are for plain, unsweetened. Flavored versions typically add 8–18g of sugar per container — sometimes more than a scoop of ice cream. Read the panel; the difference is not small.

Nonfat vs. full-fat — which is better?

Depends on the goal. Nonfat: max protein per calorie, best for a cut. Full-fat: more satiating, some studies link it to better metabolic markers, and it tastes better. Neither is "wrong."

Is milk actually healthy, or is that marketing?

By the numbers on this page: balanced enough that "healthy" is the wrong axis. It is food.
