H.A.
Greetings ~ It's not the freezing that removes the nutrients, it's the processing of the foods prior or the cooking after. Freezing does affect the structure of foods and will sometimes affect the way it feels in your mouth (mainly cream based items, most people can not tell the difference between fresh or frozen meats). If you are purchasing pre-frozen raw foods, look for minimally processed foods, especially with meat as they like to inject them with a sodium mixture. If you are freezing your own fresh meats, yes, just wash, dry and wrap securely. When fresh chicken or meat go on sale, I buy up a bunch and pre-prep it in different ways (pound chicken cutlets, cut up stew meat, cut up fajita strips, etc.), then freeze. And I often over cook meals and then portion them out and freeze them. And remember, if you are cooking vegetables in water, and then use that water for your soup or stew, you are still getting all the nutrients that were 'cooked out'.
