A Canadian government task force on trans fats is recommending that all vegetable oils and spreadable margarines have the trans fat content limited to 2% of the total fat content and all other foods be limited to a maximum of 5% of total fat content. These new regulations would decrease the average trans fat intake by at least 55%.
What are trans fats? Fatty acids in foods are made up of polyunsaturated (like safflower oil, sunflower oil and corn oil), monounsaturated (like olive oil, peanuts, and avocados), saturated (like coconut oil, palm oil, butter and cheese) and trans fats (like margarine and shortening). Saturated and trans fats are linked to coronary heart disease. The majority of trans fats are produced by the food industry when it uses a process called hydrogenation to turn liquid vegetable oils into semi-solid products. This process hardens and stabilizes the oils, enhances the flavor and extends the shelf life of food products. These trans fats also break down less easily which makes them more suitable for frying. The majority of trans fats are found in foods made with shortening,...
