AbstractThis study was conducted as a preliminary investigation of Ready Foods versus Institutional Food in a state residential facility serving approximately 500 mentally retarded residents. One administrative unit of the facility serving approximately 160 residents was used as the setting for the study. Along with residents in this unit, a variety of staff, client advocates, and volunteer workers participated in the investigation. Results were: (1) staff, client advocate, and volunteer worker responses significantly favored Ready Foods; (2) residents selected Ready Foods significantly more than Institutional Food; (3) residents displayed greater overall food waste with the Institutional Food as compared to the Ready Foods; (4) some residents displayed less choking or gagging with ready foods than with Institutional Food; and (5) out of 6 residents who were chronically overweight displayed statistically significant weight gain within one week after beginning Ready Foods and significant weight loss after the return to Institutional Food. Advantages of a Ready Foods System are discussed.
