Abstract

China is undergoing a marked transition in its diet and nutritional status patterns. This study determines the structural change in the impact of income on food consumption in China during 1989-93. Utilizing data from a longitudinal study of 3800 households in China evidence points to a shift in the relationship between income dietary structure and total nutrient intake at the macrolevel. Overall it is noted that the increase in income over time in the country coincided with a shift in the demand for inferior and normal food groups. In addition there was a pronounced increase in the income elasticity for more luxury foods during the specified period while less superior goods became more inferior over this 4-year span. Such an increase in income elasticities for total energy and for energy from fat suggest a worsening of the composition of the diet in ways that are linked to obesity and obesity-related diseases as incomes continue to rise. In view of this several implications for the formulation of future nutrition policies in China are cited.
