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 by perishable products. A low income economy may have its food imports dominantly related to grains, while a high income economy may import a wide variety of perishable products to satisfy a complex demand, including a large share of the income spent on eating outside the residence. Thus, the higher the income the more reliant an economy is on cold chain logistics.
