Economic and Cultural Assessment of the DASH Eating Plan for Low-Income African Americans: An Integrative Review

Diet is one modifiable risk factor for hypertension. The low-sodium DASH (Dietary Approaches to Stop Hypertension) eating plan has been shown to significantly reduce the risk of hypertension and cardiovascular disease. However, there is a lack of available health information on the economic feasibility and cultural acceptability of DASH for low-income African American (AA) populations who are at the most risk for hypertension. An integrative review was conducted to summarize empirical literature on the economic feasibility and cultural acceptability of the DASH plan for low-income AAs using these databases: PubMed, EMBASE, CINAHL Complete, AGRICOLA, Web of Science Core Collection, ProQuest's Dissertations, Theses Citation Index, and Google Scholar. Study elements from articles in the final analysis were extracted. Eleven (11) published works met the study's inclusion criteria. Major themes were the availability and access of healthy foods, economic impact of obtaining healthy foods, material resources for cooking, food literacy, and the cultural acceptability of the DASH plan. These findings suggest that cost and cultural familiarity inhibit low-income AAs from benefiting from the DASH plan. Additional research is needed to develop and pilot test low-cost, culturally sensitive DASH eating plans for low-income AAs.
