What is FatFats consist of carbon, hydrogen and oxygen and belong to the group of molecules called lipids. Generally dietary fat is essential for the body to function properly. Vitamin A, vitamin D, vitamin E and vitamin K are all fat soluble vitamins, which means fat is required for their digestion, absorption and transportation. There are are also essential fatty acids which are not made by the body and must be obtained from ingested fat for example linoleic acid.Fatty acids help with body functions such as blood pressure control, blood clotting and inflammation.
Fats are broken down in the body to give glycerol and fatty acids. Glycerol can be converted into glucose in the liver and used as a source of energy. The fatty acids are also a good source of energy. Fat provides 9 kCal of energy per gram which is more than double the energy provided by carbohydrate or protein (4 kCal).
Fats are grouped into the following types saturated fats, unsaturated fats, mono-unsaturated fats, polyunsaturated fats, trans fatty acids, hydrogenated fats, partially hydrogenated fats, omega-3 fatty acids, omega-6 fatty acids.
What really matters is the type of fat in the diet. Bad fats, ie saturated and trans fats, increase the risk for certain diseases while good fats, meaning monounsaturated and polyunsaturated fats, lower the risk. For a healthy diet replace saturated and trans fats (the bad fats) with polyunsaturated and monounsaturated fats.
