If the links between food and religion have weakened in a secularized world, feeding practices are still a marker of identity and attachment to "God". With this in mind, we are interested in the emergence of a consumption of halal products by Berber Moroccan migrants and their descendants living in Moselle.Our project is a desire to use this consumption through a legacy of both family, cultural and political trajectory that is specific for each actor. Eating Halal is discussed here in terms of a religious fact with multiple dimensions, both collective, material, symbolic and significant. If eating halal refers to dietary laws specific to Islam religious system, this practice does not explain why an individual meets a requirement, a prohibition. Drawing on the approaches of Michel de Certeau, Jean-Noël Ferrié and Saba Mahmood, we show how an individual, through the incorporation, embodies faith and built its membership. Far from appearing as an essentialization of feeding practices, eating halal produces new types of eaters for whom the believe is a technique designed to create for the actor a capability of agency and reflexivity.
