The 3 main types of fat in our diet are saturated fat, monounsaturated fat and polyunsaturated fat. Saturated fatty acids do not contain any carbon double bonds, as the fatty acid is fully saturated with hydrogens. Monounsaturated fatty acids, as the name suggests contain fatty acids with one carbon double bond (i.e. mono meaning one) and likewise polyunsaturated fatty acids contain two or more carbon double bonds.
