flour, consumption increases as income increases – the curves trend upward, illustrating high
income elasticities. 99 in contrast, the consumption of cassava is highest in poorer households.
if incomes were rising over time, an increase in the consumption of the goods with high income
elasticities would be expected, the consumption lines in 2007 would shift upward from 2000/01.
figure 55 illustrates that consumption of soft drinks and rice rose, as did animal products slightly.
Consumption of sugar remained stable between 2000/01 and 2007, while the consumption of
beef declined.
