Trans fat (also known as trans fatty acid) is formed when liquid vegetable oils go through the chemical process of hydrogenation to make the oils more solid. This gives food a longer shelf-life and can improve taste, shape and texture. Some trans fat also is found naturally in small amounts in certain meat and dairy products.
Partial hydrogenation, the process used to increase shelf-life of polyunsaturated fatty acids (PUFAs) / vegetable oils creates trans fatty acids. Many studies have demonstrated that trans fatty acids increase the clot forming tendency much more than saturated fats, by not only increasing LDL cholestrol to similar levels but also by decreasing the high density lipoprotein (HDL) cholesterol, (which is the good cholesterol). Several studies have found that intake of non natural trans fatty acids increases the risk of coronory heart disease. Most trans fatty acids are contributed by industrially hardened oils. Even though trans fatty acids have been reduced or eliminated from retail fats and spreads in many parts of the world, generally available deep-fried foods and baked goods are a major and increasing source.
These are then substituted by Palm oil , Palmolien , Fully hydrogenated vegetable oil.
