Question: Among patients with diabetes who are food insecure, does an intensive food-as-medicine program that provides healthy groceries plus dietitian consultations, education, and health coaching improve glycemic control compared with usual care? Findings: In this randomized clinical trial of 465 adults who were provided access to a food-as-medicine program, hemoglobin A1c levels did not improve among those who had access to the program compared with a control group; however, their engagement with preventive health care increased as designed. Meaning: Because this intensive food-as-medicine program did not improve glycemic control, these results suggest that further efforts are needed to understand how programs that address food insecurity can improve health.
