This preliminary study characterized the adequacy of planned diets in two community-based, supported-living arrangements for adults with intellectual/developmental disabilities in Montana. The goals were to clarify the residents’nutritional risks and to identify appropriate areas and means for intervention. Observations, interviews, and analyses of menus, shopping lists, and grocery receipts led to conclusions about the residents’dietary adequacy. We conclude that the food systems, with their strong (and unhealthful) food traditions, lend themselves to systematic environmental changes, including targeted practice guidelines and support materials, to improve the diets and food habits.
