Restrictions on the use of trans-fatty acids in restaurants and cafes in 11 New York states was associated with a drop in heart attacks and strokes.

Between 2007 and 2011, 11 New York state counties restricted the use of trans-fatty (PDF) acids in public restaurants and cafes. 25 New York states that did not implement restrictions were included in the analysis. Hospital admission for cardiovascular events (myocardial infarction and stroke) were measured three or more years after the restriction was first implemented.              

Three years after the restriction was implemented there was 6.2% drop in hospital admissions for cardiovascular events compared to the counties which did not implement the restriction. There was a 7.8% reduction in hospital admissions for heart attacks and a 3.6% reduction in admissions for strokes.
