A pragmatic randomized clinical trial evaluated the effect of a culturally and medically tailored meal program (MUTTON-HF) incorporating traditional Navajo foods on clinical outcomes in adults with living in rural Navajo Nation.
Among 206 participants, individuals assigned to 8 weeks of locally sourced Indigenous meals had a significantly lower risk of hospitalization or emergency department visit within 90 days compared with those receiving usual dietary advice.
Secondary analyses showed reductions in heart failure hospitalizations, blood pressure, financial strain, and food insecurity, as well as improvements in quality of life and dietary intake.
These results highlight the impact of interventions designed with community input and the importance of culturally responsive, community-based strategies to address nutrition insecurity and cardiovascular health inequities in communities.
