+Kentucky MTM pilot provides the intervention test: directly addressing food insecurity through medically tailored meals produces -9.67 mmHg systolic BP reduction in food-insecure hypertensive adults, demonstrating the causal pathway from food access to blood pressure control. This converts the correlational SDOH finding into actionable treatment evidence.

+# 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 across urban (UK HealthCare) and rural (Appalachian Regional Healthcare) sites. The medically tailored meals arm (5 meals/week for 12 weeks) achieved -9.67 mmHg systolic BP reduction, while the grocery prescription arm ($100/month for 3 months) achieved -6.89 mmHg reduction. Both exceed the 5 mmHg clinical significance threshold. Critically, standard first-line antihypertensive medications typically produce -5 to -10 mmHg systolic reductions — meaning the MTM intervention sits at the TOP of the pharmacotherapy range. This is not a marginal effect. The mechanism appears to be structural: providing hypertension-appropriate food directly to food-insecure patients removes the behavioral/access barrier that causes the 77% treatment failure rate documented in existing KB claims. The intervention works BECAUSE it addresses the binding constraint (food access) rather than adding another prescription to a population that already has medication access but cannot afford appropriate food. This is the first quantitative evidence that food-as-medicine interventions achieve pharmacotherapy-scale outcomes in the specific population where pharmacotherapy systematically fails (food-insecure hypertensives). The preprint status requires experimental confidence, but the effect size and clinical design are robust.

 The systematic review establishes that the binding constraints are SDOH-mediated: housing instability affects treatment adherence, transportation barriers prevent care access, food insecurity directly increases hypertension prevalence, and insurance gaps reduce BP control. The review endorses CMS's HRSN screening tool (housing, food, transportation, utilities, safety) as a necessary hypertension care component.

+Kentucky pilot demonstrates that food access IS the binding constraint for food-insecure hypertensives: providing medically tailored meals achieves -9.67 mmHg reduction (comparable to adding a drug) in a population that already has medication access but cannot afford hypertension-appropriate food. This explains why 77% of treated patients fail to achieve control — the treatment exists but the dietary foundation required for it to work does not.

+# Rural food-insecure populations show 81% enrollment in food assistance programs versus 53% urban enrollment, suggesting severe access constraints increase intervention receptivity rather than creating participation barriers
+
+The Kentucky pilot enrolled participants at two sites: UK HealthCare (urban Lexington) achieved 53% enrollment (49 enrolled from 92 referrals), while Appalachian Regional Healthcare (rural) achieved 81% enrollment (26 enrolled from 32 referrals). This is a 1.5x difference in uptake. The standard assumption in health services research is that rural populations face higher barriers to program participation due to transportation, technology access, and institutional distrust. This data suggests the opposite mechanism: in regions where food access is severely constrained (Appalachia has documented food desert prevalence), food assistance interventions are MORE valued because participants directly recognize the intervention addresses their binding constraint. Urban food-insecure populations may have more alternative coping mechanisms (food banks, informal networks, geographic proximity to discount grocers) that reduce perceived intervention value. This has implications for targeting food-as-medicine programs: the populations with worst baseline access may be the most receptive, not the least. Single-study data requires experimental confidence, but the magnitude of the difference (28 percentage points) is substantial.

 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.
