Does the provision of free medically tailored groceries high in fibre or healthy fats impact sodium and potassium intakes? Secondary data analysis of a randomised controlled trial with extended follow-up

Top Things to Know

Providing heart-healthy groceries through healthcare systems or food delivery programs can help patients reduce sodium intake without requiring resource-heavy interventions.

Including potassium-rich foods like fruits, vegetables, and legumes in MTG packages can help patients meet potassium recommendations.

Programs that integrate grocery delivery into clinical care can overcome socioeconomic barriers to healthy eating, making nutrition therapy practical and sustainable for large populations.

Summary of Conclusion/Findings

This randomized controlled trial examined whether providing free medically tailored groceries (MTG) high in dietary fiber or healthy fats to adults recovering from an acute coronary event influenced sodium and potassium intake. Over 12 weeks, participants received either usual care, groceries high in healthy fats, or groceries high in fiber, with follow-up at 3 and 12 months. The study found that both intervention groups experienced reductions in sodium intake compared to usual care, with the high-fiber group showing consistent reductions at 3 months (−257 mg) and 12 months (−358 mg), while the healthy fats group showed a reduction only at 12 months (−342 mg). Potassium intake increased significantly (+279 mg) during the intervention for the high-fiber group but was not sustained at follow-up. No adverse effects on sodium or potassium intake were observed, and the intervention required no additional nutrition counseling. These findings suggest that MTG provision can support long-term sodium reduction and short-term potassium improvement in cardiac recovery patients.
