Partially Hydrogenated Fats and Trans-Fats
by Shereen Jegtvig
When you look on the ingredients lists of your packaged foods, you may see ‘partially hydrogenated oil’ lurking there. Hydrogenation involves forcing hydrogen molecules into the polyunsaturated fat molecules of liquid oil. The addition of the hydrogen molecules changes the chemical structure of the fats and turns the liquid oil into a more solid shape (think about stick margarine). These fats are called trans-fats.
That’s a bad thing because partially trans-fats are worse for you than saturated fats. Trans fats raise LDL cholesterol (the bad kind), which is a risk factor for cardiovascular disease. Eating too many of these artificially created trans-fats clogs your arteries and increases inflammation.
It’s so bad, that food manufacturers are required by the United States Food and Drug Administration to indicate how many grams of trans-fat are contained in each serving of their products. And New York City has banned the use of trans-fats in local restaurants. Read more
