+Kentucky MTM pilot provides the quantitative BP reduction evidence (-9.67 mmHg MTM, -6.89 mmHg grocery prescription) that was missing from the durability literature. However, this is a 12-week pilot without 6-month follow-up data, so it cannot test the reversion hypothesis. The effect size during active delivery is now well-established across multiple studies; the durability question remains the critical gap.

+# Medically tailored meals produce -9.67 mmHg systolic BP reductions in food-insecure hypertensive patients — comparable to or exceeding first-line pharmacotherapy — suggesting dietary intervention at the level of structural food access is a clinical-grade treatment for hypertension in food-burdened populations
+
+The Kentucky MTM pilot enrolled 75 food-insecure hypertensive adults (ages 18-64) across urban (UK HealthCare) and rural (Appalachian Regional Healthcare) sites. The medically tailored meals arm (5 meals/week for 12 weeks) produced -9.67 mmHg systolic BP reduction. The grocery prescription arm ($100/month for 3 months) produced -6.89 mmHg systolic BP reduction. Both exceed the 5 mmHg clinical significance threshold. Critically, standard first-line antihypertensive medications typically produce -5 to -10 mmHg systolic BP reductions — meaning the MTM food intervention achieves the TOP of the pharmacotherapy range. This is not a marginal effect. The mechanism appears to be structural: providing consistent access to hypertension-appropriate foods removes the food insecurity barrier that prevents dietary adherence. The grocery prescription arm's smaller but still significant effect (-6.89 mmHg) suggests that even financial support without meal preparation achieves clinically meaningful results. This directly tests the SDOH → hypertension pathway identified in prior observational research: food insecurity independently predicts hypertension risk, and this study shows that REMOVING food insecurity produces pharmacotherapy-scale BP improvement. The effect size comparison to GLP-1 receptor agonists is striking: GLP-1s typically produce 1-3 mmHg systolic BP reduction in clinical trials, meaning the MTM intervention achieves 3-9x the BP reduction of the largest therapeutic category launch in pharmaceutical history. The preprint status requires experimental confidence, but the effect size is consistent with other food-as-medicine studies and the two-site design (urban + rural) strengthens generalizability.

+# Rural food-insecure populations show higher food assistance intervention enrollment (81% vs 53% urban) suggesting greater receptivity where food access is most constrained
+
+The Kentucky MTM pilot revealed a striking enrollment pattern: the rural Appalachian site (ARH) achieved 81% enrollment (26 of 32 referrals) while the urban site (UK HealthCare) achieved 53% enrollment (49 of 92 referrals). This is surprising because rural healthcare interventions typically face LOWER enrollment due to access barriers, transportation challenges, and lower health literacy. The reversal suggests that food-insecure populations in severely constrained food environments (rural Appalachia) recognize the direct value of food assistance interventions more readily than urban populations with more food retail options. The mechanism may be that in Appalachia, food deserts and limited grocery access make the intervention's value proposition immediately obvious — participants understand that without the intervention, accessing hypertension-appropriate foods is genuinely difficult. In urban settings with more food retail (even if unaffordable), the value proposition may be less immediately clear. This has implications for targeting food-as-medicine interventions: rural food-insecure populations may be MORE receptive, not less, despite typical rural healthcare access challenges. The finding challenges assumptions about rural health intervention uptake and suggests that structural food access constraints create demand for solutions that urban populations with nominal food access may not perceive as urgently needed.

 WHY ARCHIVED: Provides the quantitative BP reduction evidence that was missing from the food-as-medicine literature. -9.67 mmHg MTM, -6.89 mmHg grocery prescription. Both clinically significant, both comparable to pharmacotherapy. This is what closes the gap between "food insecurity is bad for BP" and "addressing food access is good for BP."
 
 EXTRACTION HINT: The preprint status requires a confidence level of "experimental" or "likely." The core finding is the effect size comparison: food-as-medicine achieves pharmacotherapy-scale BP reduction in food-insecure patients. Pair with AHA Boston study for the durability caveat. Also flag the rural enrollment rate surprise — this may be a claim about rural populations' high receptivity.
