The quality of meal-oriented support for people with intellectual disabilities is important for their health. The aim of the present study was to explore the experiences of meal-oriented support and diet counselling for adults with intellectual disabilities living in supported housing, from the perspective of housing staff and mothers. Five focus group interviews, including nine supporting staff members and nine mothers, were conducted. The interviews were analyzed using systematic text condensation. Five themes appeared; Extensive needs of the individual, Staff skills determine the food intake, Informal caregivers make up for shortage of support, Effective collaboration with a registered dietitian is needed and Responsibility of the organization state that professionalization of staff is needed. Lacking resources, such as time and nutritional knowledge, insufficient considerations of individual needs, and high staff turnover influence the meal-orientated services negatively. This study brings to the fore, staff working practices and the complexity of providing meal-oriented support for people with intellectual disabilities. Staff need skills to perform individually tailored support. This is best accomplished through effective collaboration between housing staff and relatives underpinned by knowledge from a registered dietitian. The working practices must be structured at the organizational level of the services.
