United States regulators have ordered the ban of trans-fat, stating that it must be banned from the food supply within 3 years.
The US Food and Drug Administration said partially hydrogenated oils (PHOs), the main source of trans-fats, are not "generally recognised as safe", and the ban would save lives by preventing fatal heart attacks.
According to FDA's Acting Commissioner Stephen Ostroff,
"This action is expected to reduce coronary heart disease and prevent thousands of fatal heart attacks every year."
Trans-fat is made by pumping vegetable oils with hydrogen which makes them solids or semi-solids and popular foods that may have trans-fats include french fries, fried meats and frosting.
The World Health Organization calls them 'toxic' even as the UK has been calling for a ban on trans-fats for several years.
