It’s now illegal for manufacturers to add trans fats to any food made or imported into the Canada. Trans fats are known to increase “bad” cholesterol, in turn raising the risk of heart disease.

Canada’s ban on the main source of artificial trans fats came into effect Monday, making it illegal for manufacturers to use the additive in any food made or imported into the country, as well as in any meals prepared in restaurants.

The ban takes aim at partially hydrogenated oils, or PHOs, which are the main source of industrially produced trans fats in all foods sold in Canada. The new regulation applies only to PHOs, not naturally occurring trans fats, which can be found in some animal-based foods such as milk, cheese, beef and lamb.
