Results of Search • Initial search retrieved 2,367 research papers. • Only six studies met inclusion criteria. – Three studies from the United States – Two studies from Sweden – One study from Italy

Key Findings • Results demonstrate a DASH-style diet can significantly reduce risk of heart disease. – Cardiovascular disease risk reduced by 20% – Coronary heart disease risk reduced by 21% – Stroke risk reduced by 19% – Heart failure risk reduced by 29%
