If you like to cook and you want your food to last until the end of days, then go get yourself a big ole' vat of trans-fat. Trans-fat, or trans fatty acids, is made via the industrial process of adding hydrogen to liquid vegetable oils.
Trans-fat is not natural, but, it's cost effective! Trans-fat helps extend the shelf-life of processed foods, like snack cakes.
Fast food chains use a lot of trans-fat - or at least they used to. Following bans on trans-fat in places like New York, a new report says fast food joints Wendy's, Burger King, and McDonald's have reduced how much trans-fat they use.
Presented at last week's National Nutrient Database Conference, researchers claim popular fast food chains have substantially cut down the use of trans-fat in their cooking oils. Foods like french fries are often cooked in trans-fat.
Even still, health advocates have been pressuring global health authorities to regulate that only trace amounts of trans-fat be allowed in food.
Comparing data on five different fast food restaurants - McDonald's, Burger King, Wendy's, Jack in the Box, and Dairy Queen - researchers found between 1997 and 2008, McDonald's, Burger King, and Wendy's significantly reduced trans-fat usage, but Jack in the Box and Dairy Queen did not.
Started in 2006, trans-fat content is required on all Nutrition Facts labels.
Since trans-fat is an unnatural compound it wreaks havoc in the body; lowering HDL, or “good” cholesterol, and raising LDL, or “bad” cholesterol.
