Data based on FDA’s economic analysis for the final trans fatty acid labeling rule, "Trans Fatty Acids in Nutrition Labeling, Nutrient Content Claims, and Health Claims" (July 11, 2003)
Basically, trans fat is made when manufacturers add hydrogen to vegetable oil--a process called hydrogenation. Hydrogenation increases the shelf life and flavor stability of foods containing these fats.
Trans fat can be found in vegetable shortenings, some margarines, crackers, cookies, snack foods, and other foods made with or fried in partially hydrogenated oils. Unlike other fats, the majority of trans fat is formed when food manufacturers turn liquid oils into solid fats like shortening and hard margarine. A small amount of trans fat is found naturally, primarily in some animal-based foods.
Trans fat, like saturated fat and dietary cholesterol, raises the LDL cholesterol that increases your risk for CHD. Americans consume on average 4 to 5 times as much saturated fat as trans fat in their diets.
Although saturated fat is the main dietary culprit that raises LDL, trans fat and dietary cholesterol also contribute significantly.

Scientific evidence shows that consumption of saturated fat, trans fat, and dietary cholesterol raises low-density lipoprotein (LDL), or "bad cholesterol," levels, which increases the risk of coronary heart disease (CHD). According to the National Heart, Lung, and Blood Institute of the National Institutes of Health, more than 12.5 million Americans have CHD, and more than 500,000 die each year. That makes CHD one of the leading causes of death in the United States.
The Food and Drug Administration has required that saturated fat and dietary cholesterol be listed on food labels since 1993. Starting Jan.1, 2006, listing of trans fat will be required as well. With trans fat added to the Nutrition Facts panel, required by Jan. 1, 2006, you will know for the first time how much of all three--saturated fat, trans fat, and cholesterol--are in the foods you choose. Identifying saturated fat, trans fat, and cholesterol on the food label gives you information you need to make food choices that help reduce the risk of CHD. This revised label will be of particular interest to people concerned about high blood cholesterol and heart disease.
However, everyone should be aware of the risk posed by consuming too much saturated fat, trans fat, and cholesterol. But what is trans fat, and how can you limit the amount of this fat in your diet?
