The bad wrap is based on bad science, plain and simple. Full fat dairy is preferable in almost all cases, when it comes to health (if not calories). Lower fat and skim products tend to either be skimmed of fat AND fat soluble nutrients, or replaced with sugar and starch.
I don't do a lot of dairy in the way of milk and icecream, because it doesn't digest well and I watch sugar, but butter, sour cream, cheese, full fat plain yogurt, kefir, and heavy cream are all excellent additions to my diet as condiments to the main courses of meat, veggies, and fruit
