I've been buying 2 percent milk at the grocery for decades. In recent years, as I've noted before, the amount of cooler space devoted to milk of different fat levels has decreased. When I picked up milk the other day I realized the amount of space devoted to 2 percent milk was down, and the proportion devoted to whole milk was up.
I'm vaguely aware of some research supporting the consumption of whole milk. Googling found this piece, along with others with titles pointing both ways.
Meanwhile I see this post. showing the dairy industry pushing for whole milk in schools.
