In February 2019 researchers from China published their review of the medical scientific literature to assess the association between the Dietary Approach to Stop Hypertension (DASH) diet and risk of coronary artery disease. Seven studies were identified, involving a total of 377,725 individuals and 15,074 diagnoses of coronary artery disease. Results showed that a higher adherence to the DASH diet was associated with a decreased risk of coronary artery disease when compared to a low adherence. A further analysis revealed that each 4-point increase in the DASH diet score appeared to reduce the risk of coronary artery disease by 5%. No indication of publication bias was identified.
