Lipoproteins are fat/protein composition, which contain triglycerides, phospholipids, cholesterol and protein. In general the higher the percentage of lipid in lipoprotein, the lower its density. Chylomicrons, which transport absorbed lipids from GI tract have the lowest density of all.
There are VLDL, which are very low density lipoproteins,
LDL's, low density lipoproteins,
HDL's , high density lipoproteins.
Healthy oils that have been hardened by hydrogenation to make them more solid are called Trans Fats. These cause serum changes, worse than those by saturated fats. trans fatty acids spark a greater increase in LDL's and a greater reduction in HDL's, producing the unhealthiest ratio of total cholesterol to HDL. It is preferable to have higher blood levels of HDL's, they have a greater protein level.
Saturated fatty acids stimulate liver synthesis of cholesterol and inhibit its excretion from the body.
Unsaturated (mono & poly) fatty acids enhance secretion of cholesterol and its catabolism to bile salts, thereby reducing total cholesterol levels.
Cholesterol is lost from the body when it is catabolised, and secreted in bile salts, eventually excreted in feces.
Cholesterol serves as the structural basis of bile salts, steroid hormones and Vitamin D, and is a major component of plasma membranes.
So cholesterol is needed but in very small quantities and only from good oils or lipids.
15% blood cholesterol comes from the diet.
85% made from acetyl CoA, by the liver and intestinal cells. In other words the body can make what it needs.
Some articles claim that our desire for fats comes from the bodies need for good oils, its craving the essential oils, such as Omega 3's.
We really should be throwing away our frying pans, only boil, poach, steam, bake, and take Omega 3's, found in cold water fish, cod liver oil, linseed oil.
