The American Heart Association has published a scientific review of popular diets. The study evaluated and scored ten known dietary patterns based on criteria agreed by scientific evidence that define heart-healthy diets.

DASH style, Mediterranean, pescetarian and vegetarine (scores above 85) are the highest scoring patterns. The DASH-style eating pattern received a score of 85. The Mediterranean diet is also perfect for meeting all Association guidelines. The 'Viking diet', the new rival for the Mediterranean diet, is not heart- healthy.
