Support for the Soup Theory of Disease

I have long been a proponent of the notion that disease is caused by lack of soup. And I was right!

Most of the bone defects that the researchers found [in victims of the Black Death] can be caused by malnutrition, and the scientists suggest that the findings may show effects of starvation on immune function. It is known from contemporary chronicles that many survived the plague, and they, the authors write, were probably well fed and healthy enough to mount an effective immune response.

They don't call matzo ball soup "Jewish Penicillin" for nothing!
