Appendix A: Agricultural Production During 1990


The following table translates the inventory of agricultural production published by the FAO into calories and protein. The products are presented in five classes. Crops such as wheat that generally are eaten by people comprise Class 1. Within the class the products are sorted from the most consumed, wheat, to the least. I show the quantity in thousands of metric tons. I show the energy or calories per 100 g and protein as percentage of the edible portion of food as purchased. In many cases, I estimate calories and protein; e.g., I used the composition of walnuts for tree nuts and of soybeans for safflower. The final columns are the trillions of calories and thousand metric tons of protein calculated from the preceding quantities and compositions.

Animal products milk, meat, and eggs make up Class 2.

Coarse or feed grains make up Class 3.

Other products not commonly eaten or fed make up Class 4.

Calories and protein consumed by draft animals make up Class 5.
