Abstract
Changes in the global food economy involve both supply-side and demand-side forces. This
paper focuses on two potentially important demand-side shifters: urbanization and ageing. An
analytical problem in the literature on this subject has been separating the effects of these
shifters from the effects of income growth, which has been correlated with them. The
evidence suggests that urbanization raises the demand for energy-dense foods that are more
easily prepared than traditional foods such as staple grains. It does not seem to increase total
intake of calories per person, but to substitute one source of calories for another, with more
consumption per person of animal products, including meat and dairy products, more
consumption of vegetable oils and wheat products, and less consumption of traditional
staples, including most grains, other than processed products made from them, and pulses. In
nutritional terms, urbanization leads to more consumption of animal and vegetable fats and
less consumption of complex carbohydrates and fiber. The effects of ageing of the population
are less well studied. They seem to be qualitatively similar to, though smaller than, the effects
of urbanization: less consumption of staple grains and more consumption of wheat products,
meat, fish and fruit.
