This study investigates changes in postnatal food choices among the Taiwanese-Han women in contemporary urban Taipei. The traditional ways of 'doing the month' food are rice-wine-based, and associated with food taboos. Recent changes in postnatal care in contemporary urban Taipei, as influenced by the prevailing western system of medical science, have led to a process of medicalization of 'doing the month' that not only challenges traditional food taboos by emphasizing a balanced diet but also introduces commercialized alcohol phobia. As a result, various body experiences are brought to the patient, and sometimes conflicts arise among the family members. In this study, I argue that, while the hot-cold dichotomy in traditional food classification still dominates, it is the increasing level of female self-awareness that controls what postnatal food is prepared and how. Through a variety of uses of rice wine, postnatal foods not only provide the patient with comfort and enjoyment, but also contribute to changes in self-identification.
