Some ``Lite'' cheeses are becoming available. Cottage cheese Huttenkäse like most products here is made with no additives or preservatives. Milk comes in whole milk (Vollmilch) with 3.8% or 3.5% fat which tastes very rich. They don't have 2% milk but they do have 1.5% milk (Fettarm) and it, too, tastes richer than our 2%. Skim milk has about 0.3% fat and is called Fettfrei or Magermilch. You can buy H-milch that is unrefrigerated but must be refrigerated after opening. This is milk that has been ultra-high heated (UHT, for ultra-high-temperature) to kill off bacteria. It keeps for up to three months. It can be good in a pinch but it tastes a bit different - not bad, just different. At a Reformhaus you can find powdered milk, fat free and low fat items as well as special foods for diabetics or people on fat/cholesterol reduced diets. If you use Benecol (cholesterol reduced margarine) in the U.S., look for Becel Pro Active here.
Quark is a German milk product that might be new to you: It's roughly like a cross between cream cheese and sour cream or yogurt cheese. It's one of the few milk products other than yoghurt which is available in skim (0.02 percent fat) as well as being available in Halbfett and Rahmstufe. You can use it for dips, or add some milk and use it as a substitution for sour cream, or add some fruit and maybe a bit of sugar for a yummy treat.
