Human food consumption
Svennilson (1954) gives estimates for consumption of cereals (wheat and rye) for all European countries during 1909-13, 1924-28 and 1934-38.
Tuve (1976) listed the upper and lower 20% of the countries with their food supply in calories per capita, and the percentage animal origin. The most affluent countries had in 1970 between 37-45% of their food supply provided by animals, with the exception of the USSR with 20%. The poorest countries had a minimum of 2-3% (Indonesia, Rwanda, Ghana) and a maximum of 13-21% (Philippines, Bolivia, Somalia). Gray (1990) presents a table of the historic development of food consumption in de USSR.
In IMAGE the human food consumption is expressed as daily caloric intake per capita. The intake is divided into 12 categories; temperate and tropical cereals, maize, rice, pulses, roots and tubers, oilcrops, meat and bovine, milk (excl. butter), pigmeat, meat of sheep and goats, and poultry. The daily caloric intake is derived from the FAO (1990), they used a region specific conversion factor for each food category.
