Jasenovac concentration camp
Like at all Nazi death camps, the food given to prisoners at Jasenovac was not enough to keep them alive.  The kind of food they were given changed over time.  In camp Brocice, inmates were given a "soup" made of hot water with starch for breakfast, and beans for lunch and dinner.  (These "meals" were served at 6:00, 12:00 and 21:00.)  Food in Camp No. III was better at first, with potatoes instead of beans.  However, in January, prisoners started getting only one daily serving of thin "turnip soup".  By the end of the year, the diet had been changed again, to three daily portions of thin gruel made of water and starch.  More changes were made, but prisoners never got enough food to keep them from starving.
