Trans fats are dangerous for your heart, because they raise low-density lipoprotein (LDL, or “bad”) cholesterol and triglyceride levels. The chief culprit you’ll see on product labels is partially hydrogenated oil. Trans fats are the result of adding hydrogen to liquid vegetable oils to increase shelf life. This may make some baked and fried foods taste better, but trans fats are very unhealthy, particularly for people with high triglycerides. In fact, trans fats should make up less than 1 percent of your total calories, according to the World Health Organization. Check your food labels: If a food contains trans fats or hydrogenated oils, leave it on the shelf.
