Trans fatTrans fat raises your LDL bad cholesterol and lowers your good cholesterol. Find out more about trans fat and how to avoid it.

Trans fat is considered by many doctors to be the worst type of fat you can eat. Unlike other dietary fats, trans fat — also called trans-fatty acids — both raises your LDL (“bad”) cholesterol and lowers your HDL (“good”) cholesterol.

A high LDL cholesterol level in combination with a low HDL cholesterol level increases your risk of heart disease, the leading killer of men and women. Here’s some information about trans fat and how to avoid it.

Some meat and dairy products contain small amounts of naturally occurring trans fat. But most trans fat is formed through an industrial process that adds hydrogen to vegetable oil, which causes the oil to become solid at room temperature.

This partially hydrogenated oil is less likely to spoil, so foods made with it have a longer shelf life. Some restaurants use partially hydrogenated vegetable oil in their deep fryers, because it doesn’t have to be changed as often as do other oils.

The manufactured form of trans fat, known as partially hydrogenated oil, is found in a variety of food products, including:

Baked goods. Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil. Ready-made frosting is another source of trans fat.Snacks. Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavor the popcorn. Fried food. Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process. Refrigerator dough. Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts. Creamer and margarine. Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils.

In the United States if a food has less than 0.5 grams of trans fat in a serving, the food label can read 0 grams trans fat. This hidden trans fat can add up quickly, especially if you eat several servings of multiple foods containing less than 0.5 grams a serving.

When you check the food label for trans fat, also check the food’s ingredient list for partially hydrogenated vegetable oil — which indicates that the food contains some trans fat, even if the amount is below 0.5 grams.
