+# Food-as-medicine interventions produce clinically significant BP and LDL improvements during active delivery but benefits fully revert to baseline when structural food environment support is removed, confirming the food environment as the proximate disease-generating mechanism rather than a modifiable behavioral choice
+
+A randomized controlled trial presented at AHA 2025 examined DASH-style grocery delivery plus dietitian support versus cash stipends in food-insecure Black adults in Boston. During the 12-week active intervention, the groceries + dietitian arm showed statistically significant BP improvement and LDL cholesterol reduction compared to stipend-only control. This confirms the causal pathway: dietary change → BP improvement works when the food environment is controlled.
+
+The critical finding is durability failure: Six months after grocery deliveries and stipends stopped, both blood pressure AND LDL cholesterol had returned completely to baseline levels. Not partial reversion—full return to pre-intervention values. As lead researcher Stephen Juraschek stated: 'We did not build grocery stores in the communities that our participants were living in. We did not make the groceries cheaper for people after they were free during the intervention.'
+
+This is mechanistic confirmation that the food environment doesn't just generate disease initially—it continuously regenerates it. When participants returned to the same food-insecure neighborhoods with unchanged food access, the disease pathway reactivated completely. The intervention proved the causal mechanism works, but also proved that episodic food assistance is insufficient without structural food environment change. The food environment is the system that overrides individual interventions when support is removed.

+AHA 2025 RCT showed that eliminating food insecurity through DASH grocery delivery + dietitian support produced significant BP and LDL improvements during 12-week intervention, but both reverted completely to baseline 6 months after program ended. This extends the observational food insecurity → CVD pathway with experimental evidence showing the mechanism is reversible during active intervention but requires continuous structural support.

 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.

+Boston food-as-medicine RCT achieved BP improvement during active 12-week intervention but complete reversion to baseline 6 months post-program, confirming that the binding constraint is structural food environment, not medication availability or patient knowledge. Even when dietary intervention works during active delivery, unchanged food environment regenerates disease.

 WHY ARCHIVED: Provides experimental confirmation (RCT level) that dietary intervention works during active delivery but fails structurally when the program ends. This is the evidence that bridges mechanism (food environment causes BP) to policy prescription (structural change required, not episodic programs).
 
 EXTRACTION HINT: The key claim is in the DURABILITY FAILURE, not the positive result. The positive result (BP improved during program) is expected and not novel. The reversion to baseline is the surprising, claim-worthy finding. Extract: "active food-as-medicine programs improve BP but don't create durable change without structural food environment transformation." Connect to the continuous inflammation mechanism.
