People living in areas that restrict trans fats in foods had fewer hospitalizations for heart attack and stroke compared to residents in areas without restrictions, according to a study led by a Yale researcher. This finding suggests the benefit of limiting trans fats could have widespread impact as trans fat restrictions are set to expand nationwide.
The study was published April 12 in JAMA Cardiology.
Minimal amounts of trans fat intake are linked to greater risk of cardiovascular disease, the leading cause of death worldwide.

To study the impact of restricting trans fats, Dr. Eric Brandt and his co-authors compared outcomes for people living in New York counties with and without the restrictions. Using data from the state department of health and census estimates between 2002 and 2013, the researchers focused on hospital admissions for heart attack and stroke.
They found that three or more years after the restrictions were implemented, people living in areas with restrictions had significantly fewer hospitalizations for heart attack and stroke based on trends in similarly urban areas without the restrictions. The decline for the combined conditions was 6.2%.
