Trans fats are found in two forms - natural, which occur in some animal products and aren’t considered harmful, and artificial, which are hydrogenated vegetable oils and have serious health consequences. These fats occur when vegetable oils are chemically altered to stay solid at room temperature, which gives them a much longer shelf life ( 4). However, artificial trans fats - otherwise known as industrial trans fats or partially hydrogenated fats - are hazardous to your health. However, there is growing disagreement on whether CLA is actually beneficial, and more definitive studies are needed ( 2. It is believed to be beneficial and is marketed as a dietary supplement. The best-known ruminant trans fat is conjugated linoleic acid (CLA), which is found in dairy fat. Several reviews have concluded that a moderate intake of these fats does not appear harmful ( 1). However, dairy and meat eaters needn’t be concerned. They form naturally when bacteria in these animals’ stomachs digest grass. Natural, or ruminant, trans fats occur in the meat and dairy from ruminant animals, such as cattle, sheep, and goats. They come in both natural and artificial forms. The production of trans fats is a result of partial hydrogenation. Trans fats may be monounsaturated or polyunsaturated. A trans bond creates a straight chain, whereas a cis bond results in a chain that is bent. The type of bond affects the shape of the fatty acid chain. Trans fats, or trans-fatty acids, are a form of unsaturated fat. Trans fats are unsaturated fats with trans double bonds instead of cis bonds.
