The purpose of this article is to analyse the influence of social class on nutrition knowledge and food preferences among Chinese urban adults with an emphasis on the middle class. The empirical investigations conducted as part of this research are based on data from the China Health and Nutrition Survey for 2009. First, we propose a multidimensional definition of social class that combines income, occupation and education to highlight the heterogeneity of the Chinese middle class. We identify four distinct groups: the elderly and inactive middle class, the old middle class, the lower middle class and the new middle class. In a second step, we assess the influence of social class on nutrition knowledge and food preference indices. Our results show that adults belonging to the elderly and inactive middle class and to the new middle class have better nutrition knowledge and healthier food preferences than their poorer counterparts.
