A study has found, people living in areas that restrict trans fats are less prone to heart attacks compared to residents in areas without restrictions.
Trans fats are a type of unsaturated fat that, if consumed regularly, increase the risk of coronary heart disease.
Trans fatty acids, or trans fats, are commonly found in fried foods, chips, crackers and baked goods.
The study highlights the use of public policy to improve the cardiovascular health of a population.
Some communities in the US, most notably New York City, have eliminated the use of trans fats in restaurants and eateries in recent years.
To study the impact of restricting trans fats, researchers 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 the bans had significantly fewer hospitalizations for heart attack and stroke when compared to similar urban areas where no limits existed.
The decline for the combined conditions was 6.2 per cent, said the study published in the journal JAMA Cardiology.
