Rising incomes per capita are associated with a diversification of the diet, including a higher consumption level of fruits, vegetables, and meats. Higher-income economies thus have a greater share of their food imports accounted for by perishable products. A low-income economy may have its food imports dominated by grains, while a high-income economy may import a wide variety of perishable products to satisfy complex demand, including a large share of income spent on eating outside the home. Thus, the higher the income, the more reliant an economy is on cold chain logistics.
