The Food and Drug Administration, FDA, of the USA took a major step to ban trans-fat from the U.S. food supply. The agency estimates that this decision could reduce coronary heart disease and prevent thousands of heart attack deaths every year. Companies will have three years to remove partially hydrogenated oils from their products. 
Products with trans-fat derived from partially hydrogenated oils have increasingly vanished from grocery stores and restaurant menus in recent years amid widespread agreement on the risks they pose to public health.
