Mold poisoning and population growth in England and France, 1750-1850.

Abstract

Climatic and dietary changes may have reduced the incidence of mold poisoning in England and France, 1750–1850, thereby stimulating fertility and reducing mortality. Because mold poisons developed in cereals, the staff of life was often the scepter of death. When people ate less rye and more wheat or less wheat and more potatoes, even without increasing their caloric intake or improving their nutrient balance, their chances of survival improved.
