Medically tailored groceries lower HbA1c in type 2 diabetes

Medically tailored groceries and diabetes management: what happened

Medically tailored groceries and diabetes management were tested in a randomized controlled trial that paired monthly grocery support with recipes and telenutrition counseling.

The study, published in Circulation, enrolled 460 Medicaid-insured adults with type 2 diabetes and elevated HbA1c (≥7.5%) and assigned them to usual care or one of two medically tailored grocery (MTG) support levels for six months.

• Usual care: 153 patients
• Lower-dose MTG: 153 patients ($100 to $170 per month)
• Higher-dose MTG: 154 patients ($135 to $210 per month)
• All MTG participants also received recipes and telenutrition counseling

What the evidence shows about medically tailored groceries and diabetes management

Medically tailored groceries and diabetes management were linked to larger HbA1c drops than usual care over six months in this randomized trial.

Compared with baseline, HbA1c declined by 0.66 points in the intervention group and 0.25 points in the control group, and similar reductions were seen with both the lower-dose and higher-dose MTG arms.

• HbA1c change vs baseline: −0.66 points (MTG intervention) vs −0.25 points (usual care)
• Food security odds increased: 2.12
• Nutrition security odds increased: 3.65
• No significant changes reported in hypertension or body mass index

Who this applies to (and why the details matter)

Medically tailored groceries and diabetes management results in this report apply to Medicaid-insured adults with type 2 diabetes, elevated HbA1c (≥7.5%), and social needs who were studied for six months.

The authors reported that results were similar across prespecified subgroups, including sex, education, baseline food security, baseline nutrition security, and baseline HbA1c level, and that findings persisted after adjusting for baseline demographics, food insecurity, nutrition insecurity, self-reported health, comorbidities, and medication changes.

• Population: Medicaid-insured adults with type 2 diabetes and HbA1c ≥7.5%
• Duration: 6 months
• Subgroups tested: sex, education, baseline food security, baseline nutrition security, baseline HbA1c
• Adjusted analyses included: demographics, comorbidities, and medication changes

Practical context for metabolic health: how to interpret this finding

Medically tailored groceries and diabetes management may work through improved access to healthier foods alongside nutrition support, rather than through weight loss or blood pressure changes in this study.

In a statement included with the report, lead author Claudia Nau said the trial suggests food-based support can lower blood sugar “above and beyond the health care” patients receive and may be meaningful for those facing economic and social barriers.

• If you’re evaluating programs, note that MTG here included both groceries and ongoing nutrition support (telenutrition)
• The study did not find significant changes in body mass index or hypertension, even as HbA1c improved
• Both lower- and higher-dollar MTG ranges showed similar HbA1c reductions in this trial

Limitations and caveats to keep in view

Medically tailored groceries and diabetes management findings here are limited to what was tested: a six-month, grocery-plus-telenutrition program in Medicaid-insured adults with elevated HbA1c.

The report does not indicate significant changes in hypertension or body mass index, and it does not establish how results might differ in people without Medicaid coverage, without social needs, with lower baseline HbA1c, or over longer time periods.

• Timeframe was six months; longer-term durability is not addressed in this report
• The intervention combined groceries, recipes, and telenutrition counseling, so the effect cannot be attributed to groceries alone
• No significant hypertension or BMI changes were reported alongside HbA1c improvements
