According to Auschwitz.org, prisoners were given three (measly) meals a day. For breakfast, they had a half liter of what they called coffee but was actually just water with a grain-based coffee substitute. Of course, it was not sweetened. For lunch, they would get a liter of soup that contained potatoes, rutabagas, groats, rye flour, and/or Avo food extract. This was usually so unappetizing that newly arrived prisoners struggled to eat it due to disgust. For supper, they received 300 grams of black bread, 25 grams of sausage, marmalade or margarine. Due to the lack of full nutrition or sufficient calories, they would lose a lot of fat, muscle, and even their organs began to suffer.
