CIA report on USSR calorie consumption, not quite as nice as commies make it sound.

The Soviet people ate mostly potatoes and bread, and only had 8% of their diet was meat. Low quality meat I might add. Basically, old cows, hotdogs, and trash fish like carp. The USA on the other hand was mostly a meat and potatoes diet, with over 20% consumption being meat, and the quality of the meat is much higher.
