Cardiovascular disease is the leading cause of death globally, accounting for one in every three deaths, with nearly half of deaths in lower-income countries among people younger than 70 years. WHO has identified the elimination of industrially produced trans fat (an artificial product contained in partially hydrogenated oils) from the food supply as an effective and cost-effective intervention to prevent cardiovascular disease.3 Industrially produced trans fat causes an estimated 540 000 deaths each year worldwide. This chemical is toxic to people even at low levels of intake: trans fat clogs arteries and increases the risk of myocardial infarction and death. There is some evidence that it might also increase the risk of other health problems, including type 2 diabetes. (Comment)
