The surge in malnutrition prevalence of underweight children under five from 17.9% to 19.6% in the 2007-2013 period, indicates that Indonesia is facing problems in terms of public health. Previous studies showed that the nutritional status and the health of children are concerned with the social practices of their food choices. The purpose of this study is to identify the forms of social structure and analyze the structures that play a role as inhibitors or activators social practices of food choice for children. This study involved 200 people of the main organizer of family food from the two communities in West Java province. Communities chosen have characterized the local community of highland and lowland agriculture. The results show that the structures that play a role as inhibitors or activators social practices of food choice in the highland community are the selection of food supplied from outside the community (structure of domination), income (structure of domination), and access to means of transportation (structure of domination). Meanwhile , at the community of lowland , structural inhibitors and activators social practices of food choice were identified as the food regulation for children who suffer from pain (structure of legitimacy), norms of parenting (structure of legitimacy ), a selection of food supplied from outside the community (structure of domination) and family support (structure of domination).
