Continuing with data series regarding World War II, I have found this data set (still in McNab’s fascinating book) concerning the daily intake of food derived from the ration tickets emitted. Even if I reproduce this data here, I might venture a word of warning regarding the “food intake” in this case. It concerns only “german” civilian and not the vast population of slave labourers forced to toil under the yoke of the Nazis. Let us remember that in January 1945, there were 6,691,200 individuals working in Germany as slaves (including prisoners of wars and political prisonners). This included all the “races” which the Nazis considered as inferior (Balts, Russians, Yugoslaves, Jews, Gypsies, Czechoslovaks, Ukrainians and Poles) who died in greater numbers than their French, Belgians, Dutch, English or Italians counterparts due to intentional malnourishment by the Nazis. It seems reasonable to assert that the real food intake for all individuals within the Third Reich during World War II was considerably lower than those reported in the data below.
Note also that McNab mentions that the prewar calorie intake was close to 3,000 kcals per day.
