A randomized controlled trial of 460 Medicaid-insured adults with poorly controlled type 2 diabetes in southern California tested whether medically tailored grocery (MTG) deliveries — including weekly produce, recipes, and optional telenutrition counseling — could improve glycemic control and food security over six months. Compared to usual care, MTG participants saw significantly greater reductions in HbA1c (−0.40 points) and were more than twice as likely to achieve food security and nearly four times as likely to achieve nutrition security, with consistent results across demographic subgroups and both lower- and higher-dose arms. These findings from one of the first randomized trials of MTG provide strong evidence that home-delivered medically tailored groceries can meaningfully improve blood sugar control and food and nutrition security among racially and ethnically diverse, low-income patients with diabetes.
