What are polyunsaturated fats?
Many people believe that fat consumption is bad for you. Although it is partly true, it is not quite accurate. Some fats, such as lard and other margarines, are saturated fats that can be harmful to your health. Other fats such as monounsaturated and polyunsaturated fats may actually be good for you. Polynaturated fats are those fats that have less hydrogen in their chemical structure than saturated fat.
The chemical structure of fatty acids consists of hydrogen and carbon. The saturated fatty acid has individual bonds between carbon atoms and carries the maximum amount of hydrogen capable of holding. Polynato fat has a double bond between some of his carbon atoms, which means there are fewer hydrogen atoms than atoms of saturated fat. It is this chemical characteristic that gives polyunsaturated fat its relatively low melting point. The chemical structure also means that these fats tend to move easily.
polyunsaturtuky Ated can naturally find in manyproducts. Vegetable oils and fish are two such sources. Fatty fish, such as salmon, are full of particularly important polyunsaturated fat known as omega 3 fatty acid. Although necessary for the body, this fat is not produced by the body. Instead, it must be obtained from external sources.
Scientists recommend eating polyunsaturated fats because they can help human health. These fats can increase good cholesterol when lowering bad cholesterol. In other words, polyunsaturated fats can help reduce the risk of cardiovascular disease. Many people now cook with vegetable oil instead of saturated fat, such as lard.
Not all unsaturated fats are good for you. Unsaturated fats usually remain liquid and unstable at room temperature, but there is a process that can be more stable: hydrogenation. This is the process of shaggy to make margarine. Partially hydrogenated fat, sometimes calledTrans -tuk is an unsaturated fat that has added hydrogen to it to make it more stable. These types of fat tend to remain solid at room temperature as well as saturated fat.
It has been shown that trans -uky is harmful to human health. These fats can cause a decrease in good cholesterol and increase the wrong. This process can lead to health problems such as cardiovascular disease. For this reason, some countries, including Denmark, have moved to disabling trans -uks. In other countries, including the United States, trans -uks are gradually eliminated from many fast food chains, although many states do not require them.
