Saturated Fatty Acids Saturated fat is solid at room temperature. This can be clearly seen in the marbling effect of beef or the firm consistency of butter. Saturated fats raise levels of blood cholesterol (total cholesterol, LDL cholesterol and HDL cholesterol) and triglycerides, (fatty materials) in the bloodstream, which can dramatically increase an individual’s risk for heart disease. 4.

Trans fatty acids Trans fatty acids Trans unsaturated fatty acids, or “trans fats,” are created when hydrogen atoms are added to unsaturated fats through hydrogenation of vegetable oils, a manufacturing process invented in early 20th Century. In trans fats the double bonds are in the trans configuration instead of the cis configuration. 5.

Trans Fatty Acids The major contributor of trans fat in the American diet is processed foods containing partially hydrogenated vegetable oils. These oils are used in everything from potato chips and other snack foods, margarine and shortening, to deep fried and fast foods. In addition, small amounts of trans fats can be found naturally occurring in meats and dairy products. 5.

Trans Fatty Acids Trans fats or “partially hydrogenated” oils (those oils that have gone through the hydrogenation process) acquire many of the properties of saturated fats and are less prone to spoilage. Solids at room temperature, they are also a very costeffective substitute for butter since they are derived from a plant source rather than an animal source. 5.

Trans Fatty Acids In the body, trans fat has been shown to be a greater hazardous risk factor for heart disease than saturated fat. Studies have shown that dietary trans fats can increase levels of “bad” LDL cholesterol and decrease levels of “good” HDL cholesterol. Studies have also shown that dietary trans fats can increase triglyceride levels and lipoprotein-a levels, both risk factors for coraonary heart disease. 5.

Trans Fatty Acids Most fatty acids can be produced in adequate amounts by the body, with the exception of the two unsaturated essentialfatty acids (EFAs), which must be consumed through the diet. Unfortunately, these EFAs are removed during hydrogenation because they tend to spoil relatively quickly. Therefore, even though trans fatty acids are classified as “polyunsaturated,” the intake of these oils tends to provide all the negative health consequences commonly associated with saturated fat without any of the benefits of the EFAs found in naturally occurring polyunsaturated fats. 5.
