There have been numerous reports that the nutritional intake of many hospitalized patients is sub-optimal, but there is little published information about patients' diets in Australian hospitals. In this study, the nutritional intake of patients in general medical wards of an Australian acute care hospital was assessed. Although the hospital diet can provide adequate energy and nutrients, many patients may not consume sufficient food to meet their needs. The estimated energy intake of about one-third of patients was very low, and vitamin C, calcium and zinc intakes were also of concern. The implications are discussed and recommendations for improved nutritional care are suggested.
