Food pyramid

Trans fats

Hydrogenated Vegetable Oil (or trans fats)

Hydrogenated vegetable oils are created through a process in which hydrogen is added to vegetable oil to make a longer-lasting, solid fat form. Companies use hydrogenated oil in foods because they give food a desirable texture and taste and help them last a long time. As a rich source of trans fats, or trans fatty acids, hydrogenated vegetable oil can increase your LDL, or "bad," cholesterol; lower your HDL, or "good," cholesterol; and increase your risk for heart attack and stroke. The American Heart Association recommends limiting trans fats to less than 1 percent of your total daily calories or roughly 20 calories within a 2,000 calorie-per-day diet. Common sources include stick margarine, shortening and commercially prepared pastries, french fries, cakes, crackers, cookies, frosting and other foods that list hydrogenated vegetable oil as an ingredient.
