Social capital and empowerment are increasingly used as key concepts integrated into methods of building healthy communities and as means of explaining inequities in health status within the field of Health Promotion. Although applying these concepts in a public health context offers a more holistic and socially oriented approach to health, problems arise when they are used in an imprecise and inconsistent manner. Health Promotion ideology tends to be transformed into politico-ideological complexes of power that enforce either a republican or a neoliberal perception of what the good life consist of. This may lead health professionals to participate in political projects dressed as pure health promotion that risk neglecting the various ways people may become empowered or socially engaged in their communities. We use two examples to illustrate these tendencies. Both examples arise from community building projects that demonstrate intertwined use of empowerment and social capital as part of political discourse. However, it is our primary aim to account for the different origins of the concepts in order to clarify their differences and similarities and to discuss their potentials in the context of Health Promotion. We draw on a range of theories such as those suggested by Bourdieu, Coleman, Putnam, Mayo, Rappaport and Eklund.
