However, none of these foods are high in energy, and the typical English farmer was accustomed to a diet that gave him almost six thousand calories a day. To get these calories, he ate a normal daily diet of one pound of meal or peas cooked up in a porridge, pudding, or bread, over a pound of butter and cheese, and a full gallon of strong, dark ale. Some dried or corned meat and fish were also eaten but usually only in small amounts—quarter pound a day. The Englishmen in the 1620s certainly did not live on flesh alone. William Bradford, for example, described a season of semistarvation, when “the best they could present their friends with was a lobster or a piece of fish without bread or anything else but a cup of fair spring water.” Simply to meet his daily caloric needs, a Pilgrim would have to eat a twenty-pound lobster at breakfast, lunch and supper. As they lacked dairy cows in 1621 and their peas and barley were insufficient, their survival hinged on the Indian corn. If this crop failed, so would the pilgrimage.
